Introduction
The fiscal policy at the state level interacts with people and seeks to maximize people’s
welfare. Indian states today share a larger responsibility in the implementation of govern
ment programmes and in influencing all social and economic parameters necessary to
achieve at least three-fourths of the Sustainable Development Goals (SDGs) by 2030.
Reflecting on these growing responsibilities, state budgets in India have ballooned in size
during the current decade. In terms of total receipts and expenditures together, the size of
the state governments is about three times that of the Central government, highlighting
the importance of state finances in the overall public finances of the country. The share of
state governments in general government expenditure (Centre plus states), usually
termed decentralization ratio in international parlance, hovers around 60% compared
with the global average (advanced and emerging market economies) of around 30% (IMF,
2014). While the focus of the states has been to meet the growing demand for public
services through higher capital and developmental expenditure, they have had to operate
within the available budgetary space and manage trade-offs leading to higher
borrowings1 and an increase in debt, thus underscoring the need to focus on states’
finances for medium-term macroeconomic stability and orderly financial market
conditions.
At an aggregate level, fiscal deficits of states taken together have broadly remained in
line with states’ Fiscal Responsibility Legislation (FRL) targets, except during the Ujwal
DISCOM Assurance Yojana (UDAY) years (2015–16 and 2016–17). There is, however,
a tendency in the post-FRL period, on the part of the states, to meet deficit targets by
cutting down expenditure, with developmental expenditure being the usual soft com
promise, thus raising questions on the quality of fiscal consolidation with implications for
long-term sustainability (Chakraborty and Dash 2017). States have also had to adjust to
various fiscal shocks at periodic intervals in the form of schemes like farm loan waivers, the
Financial Restructuring Plan (FRP), and UDAY, which in turn exacerbate expenditure
pressures and increase debt. Tax reforms such as the Goods and Services Tax (GST),
though expected to benefit the economy, have also limited the revenue-raising auton
omy of states. In the medium term, the state governments may have to further increase
their spending to meet the need for growing urbanization. It is, therefore, important to
analyse and understand states’ finances from a sustainability perspective and then assess
their capabilities to meet evolving demands.
Analysing the debt sustainability of state governments in India is important for three
reasons: first, unlike the Centre, states’ debt shows an upward trend despite consolidation
in terms of conventional gross fiscal deficit to gross domestic product (GFD-GDP) ratio
thus hinting at the increasing influence of off-budget borrowings on which available data
are limited. Second, most state public sector enterprises (SPSEs) are running in losses with
weak cost recovery mechanisms. Guarantees given by state governments, which repre
sent off-budget borrowings for the states, have been on a rising trend. The majority of
these guarantees are given to the power sector, with the precedence of these liabilities
falling on states’ budgets, as has happened thrice in the 13 years from 2002 to 2015, under
One Time Settlement (OTS), FRP and UDAY.2 Third, no holistic analysis of states’ debt,
incorporating both conventional debt and off-budget debt, has been attempted,
although the existing literature suggests the need to do so.
Looking at the literature on the subject in the Indian context, the latest attempt to
analyse states’ debt was made by Kaur, Mukherjee, and Ekka (2018), a study which
concludes that while conventional debt may be sustainable for states, a comprehensive
debt sustainability analysis incorporating off-budget items/guarantees into states’ debt is
needed. Accordingly, this paper incorporates contingent liabilities like state government
guarantees in the analysis to assess the debt sustainability of states. The existing literature
across the globe has also started focusing on this aspect. Large debt spikes globally over
the last decade have been more due to stock-flow adjustments via contingent liabilities
realizations, under-reporting of deficits, valuation effects, etc., rather than large primary
deficits (Jaramillo, Mulas-Granados, and Kimani 2017). Studies also emphasize the need to
improve fiscal transparency regarding off-budget operations which have become
a conduit to circumvent the fiscal rules (Von Hagen and Wolff 2006). The paper also
adds to the literature in terms of improved temporal and spatial coverage. This is the first
state-level study to use post-UDAY period data up to 2017–18.3 Also, it covers all the
states, marking an improvement over earlier studies which covered select states.4 It may
be noted, however, that the empirical analysis in the paper is for period, 2004–05 to 2017–
18, thus excluding the current COVID-19 pandemic period.
The rest of the paper is organized as follows: Section II examines in depth the trends in
subnational debt,5 with a focus on guarantees. Section III outlines a review of the select

literature. Data and methodology adopted for the analysis are provided in Section IV.
Results, based on both indicator-based approach and empirical approach, are presented
in Section V. Section VI sets out the concluding observations.

During the past decade, in order to meet fiscal targets amidst the rise in revenue
expenditures states very often took recourse to curtail capital expenditure. There are also
instances of pushing the capital expenditures to SPSEs by giving them guarantees with
a concomitant rise in off-balance-sheet expenditures (CAG, 2019). Accordingly, while
budgetary support to the SPSEs to meet their capital requirements saw a gradual decline,
issuance of guarantees by state governments helped these entities to borrow from the
market.7 There were thus, several positive gains from these guarantees. First, it has helped
states to undertake capital expenditure in key infrastructure sectors like utilities, trans
portation, housing, urban development and other welfare projects of state governments
(RBI, 2002). Second, operating through SPSEs helps states achieve some of their macro
economic goals, particularly in sectors characterized by market failures. Third, it helps
states get over their hard budget constraint. However, conducting capital expenditure
through SPSEs with the use of guarantees, while desirable, has been fraught with
6 S. MISRA ET AL.
challenges for state entities. The weak cost recovery mechanisms very often make them
a source of fiscal risk for state budgets (ECB, 2011; FC XII, 2005; FC XIV, 2015), either
implicitly through repayments or explicitly through the takeover of outstanding debt. The
poor financial performance and weak balance sheets of the SPSEs increase the vulner
ability of state governments towards the invocation of guarantees, a frequent occurrence
in the past under schemes like OTS, FRP, and UDAY. Also, given the lack of transparency
with regard to guarantees, concerns have been raised on its usage and quality of
expenditure.
Certain institutional mechanisms are put in place to safeguard against the excessive
reliance of SPSEs on guarantees and any likely invocations. States impose a guarantee fee,
which varies from 0.5% to 2.0% of guarantees issued, depending upon the quality of the
borrower and states’ fiscal stance, though very often these are waived off. The optimal or
sustainable level of such guarantees is based on annual incremental guarantees as a ratio to
GSDP or total revenue receipts specified in the various states’ Government Guarantees Acts or
fiscal responsibility legislations (FRLs) of states; otherwise administrative limits are fixed, albeit
not all states have such caps/limits. States are required to set up the Guarantee Redemption
Fund (GRF) with the Reserve Bank using the guarantee fees. It is supposed to be used to make
payments emanating from guarantees issued on behalf of state-level bodies as per the
Twelfth Finance Commission (FC-XII) recommendation (RBI, 2019). As of 1 May 2018, this
rule is adhered to only by 12 states, which have established their GRF. Moreover, some states
have inadequate funds. On an aggregate basis, corpus in GRF hovers at less than 1.5% of
outstanding guarantees indicating small buffers if crystallization of guarantees takes place.
Needless to say, there are differences amongst states in terms of awareness about fiscal risk
associated with the issuance of these guarantees and putting an appropriate mechanism in
place to minimize the spill over effect onto state budgets from guarantees.
Nevertheless, the information base on state governments’ guarantees is very weak as
data on guarantees are generally not reported explicitly by state governments in their
budget documents. The Comptroller and Auditor General (CAG) of India, through its state-
wise report of state government finances, releases data on guarantees, though there is
a lag of two years in the reporting of the same. Against this backdrop, the following
analysis relies on historical data from these reports and is supplemented with data
obtained from RBI’s annual publication of state finances.8
The outstanding guarantees of states witnessed a declining trend in the post-FRBM
period, plummeting from 5.4% of GDP at end-March 2006 to 2.0% of GDP at end-March
2017 (Table 2). The decline in guarantees is primarily driven by the guarantees of the
power sector being subsumed in state government liabilities under UDAY, which is
typically reflected in the corresponding rise in debt levels of state governments.
However, in 2017–18, guarantees witnessed a significant jump to 2.5% of GDP (year-on-
year growth of about 38%), indicating early signs of fiscal risks (Chart 5).9 Likewise, the
augmented debt, which is the sum of conventional debt and guarantees, has recorded
a rise and stood close to 28% at end-March 2018.
In terms of sectoral distribution, guarantees provided to power utilities remain domi
nant – greater than 60% (on average) of total outstanding guarantees. For a few states like
Rajasthan, Uttar Pradesh, Tamil Nadu, Meghalaya, Manipur, and Himachal Pradesh, guar
antees taken by the power sector account for over 80% of total guarantees followed by
the transport sector (Chart 6).

Rearranging we get,

MACROECONOMICS AND FINANCE IN EMERGING MARKET ECONOMIES 9
The condition for debt sustainability is to place the debt on a stable or declining trajectory
which specifies Δ bt ≤ 0, as per equation 4.11 Fiscal policy is thus unsustainable when gt
= rt and gt < rt as debt grow linearly in the case of the former and explosively in the case
of the latter. Debt is sustainable when gt > rt. This is considered to be one of the necessary
conditions for sustainability (in line with Domar 1944). The other condition is that the
primary balance (pb) has to be positive and large. However, Δ bt ≤ 0, this condition can be
achieved even with primary deficits (pb<0) if the same is offset by a sufficiently large
negative interest-growth differential (rt – gt). Since the government in emerging econo
mies, including India, usually run primary deficits, they are dependent on a negative
interest-growth differential to contain the debt-GDP ratio. It follows that if India were not
able to maintain its growth rate and if interest rates start rising, then the country’s debt-
GDP ratio could begin to spiral upwards.
For advanced economies, the interest-growth differential is usually close to zero;
further, this differential should not exist in the long run, as is advocated by growth
theories. Thus, if rt – gt is zero, then the primary balance must also be zero or in surplus
to satisfy the condition for debt to be sustainable. These are some of the theoretical
underpinnings which are utilized to assess debt sustainability in the following standard
frameworks.
cointegration approach. In the Indian case, studies by Buiter and Patel (1992) and Pradhan
(2014) used the unit root approach, while Jha and Sharma (2004) and Tronzano (2013)
relied on the cointegration approach.
Given the limitations of the aforementioned model-based approaches, the Bohn
approach, which estimates the fiscal policy response function, emerged as an alternative
and has been extensively used to assess the sustainability of public debt policies amongst
different countries (Ostry and Abiad 2005; Adams, Ferrarini, and Park 2010; Greiner and
Kauermann 2008; Haber and Neck 2006; Kaur, Mukherjee, and Ekka 2018; Renjith and
Shanmugam 2018). The economic intuition behind the Bohn approach is If governments
run debt today, how will primary balances be impacted to assess whether public debt is
sustainable or not? Many studies have used this approach to explore the issue of debt
sustainability either in a panel framework or time series; however, results are subject to
the underlying assumptions and analytical techniques used to perform the analysis.
A panel estimation study by Adams, Ferrarini, and Park (2010), which combined countries
of Central Asia, East Asia, the Pacific, Southeast Asia, and South Asia for a relatively small
period, indicated public finances of developing Asia to be in good shape.
In the context of India, while studies have conventionally analysed debt sustainability
for the Centre and general government (Centre plus states) (Hakhu 2015; Mohanty and
Panda 2019; Rajaraman and Mukhopadhaya 2004; Rangarajan, Basu, and Jadhav 1989;
Seshan 1987) and both for domestic and external debt (Cashin and Olekalns 2000), the
existing empirical literature on states’ debt sustainability remains sparse with mixed
results. Early studies by Tiwari (2012) and Misra and Khundrakpam (2009) which cover
the initial years of the post-FRBM period when the debt was at a relatively higher level
found evidence of debt unsustainability in the long run, while studies such as Renjith and
Shanmugam (2018) and Kaur, Mukherjee, and Ekka (2018) covering the later time period
observed debt to be sustainable. Regardless of the time period, results amongst studies
vary on based on the estimation method adopted. Summary results of select empirical
studies dealing with this research question are presented in Table 3.
A review of the Indian literature available on public debt sustainability clearly reveals
that most studies on the subject have limited their analyses to conventional debt
sustainability and have not assessed the potential risks from contingent liability realiza
tions. Given the fact that a significant portion of the guarantees accrues to the financially
underperforming state power-sector utilities, the prospects of their crystallization are
higher and therefore the consequent financial burden may fall on states’ budgets. It
should be noted that this issue has been highlighted by other studies as a potential
research gap (European Central Bank (ECB) 2011; Kaur, Mukherjee, and Ekka 2018).12
Contingent liability realizations have been ascribed to be a more important cause than
an addition to the primary deficit behind debt spikes across countries (Jaramillo, Mulas-
Granados, and Kimani 2017).
Against this backdrop, this study attempts to address this research gap specifically in
the Indian context by including the post-UDAY period (2015–17) when debt swelled up
sizably; incorporating a larger number of states, thereby improving spatial coverage vis-à-
vis existing studies; and, lastly, by adding the contingent liabilities in the form of state
government guarantees into the conventional debt analysis.

where P is the primary balance-to-GDP in year t; D t-1 is debt stock in t-114 and X denotes
control variables, viz. real GDP gap, revenue receipts, primary expenditure, etc. ‘β’ is the
principal coefficient which measures the response of the primary balance to variations in
debt. If a rising debt-to-GDP ratio leads to a rise in primary balance, then debt tends to be
sustainable.
Equation (5) has been estimated using a fixed-effect model and/or random-effects
model. The former allows for all unobserved factors (varying across states though remain
ing constant over time) to be correlated with the explanatory variables, while the latter
assumes that they are uncorrelated with the explanatory variables and so are included in
the error term (Gupta and Ahmed 2018). The Hausman specification test has been applied
to decide upon the fixed effects/random effects model wherein the null says there is no
significant difference between these two estimations.15
In addition, regressions are carried out with Feasible Generalized Least Squares (FGLS)
to further check the robustness of empirical results (Ostry and Abiad 2005; Adams,
Ferrarini, and Park 2010). The classic OLS regression assumes independent identically
distributed (i.i.d) error and independent autocorrelation structure. But in many cross-
sectional data sets, the variance for each of the panels differs. Recognizing that this study
uses data from heterogeneous states that may have variations of scale, ruling out
heteroscedasticity could be important. This problem of heteroscedasticity can be coun
tered if the variance-covariance matrix of the error term is known. There are typically two
ways to address this issue. One can either (a) assume the structure of the variance-
covariance matrix which is known as weighted least squares (WLS) estimation or/and
(b) estimate it empirically from ordinary least squares (OLS) rather than assuming, referred
to as FGLS estimation. Furthermore, FGLS estimation has an advantage that it can also
correct for cross-sectional correlation and autocorrelation, if any occurs (Greene 2012).
Data
The study uses annual time series from 1992–92 to 2018–19 to perform the indicator-
based analysis for all states, while a panel analysis is conducted for the period 2004–05 to
2017–18 for 26 states. The choice of states and time period in the panel data has been
determined by the availability of guarantees data, though we have tried to remain as
comprehensive as possible. Since data points for the variable outstanding guarantees
were not available for two states, viz. Goa, and Jharkhand, augmented debt could not be
obtained. Also, with the Telangana region being merged with Andhra Pradesh, few data
points were available for Telangana’s guarantees data. Consequently, 26 states are
considered over a period of 14 years. As debt stock is taken with a lag of one year, the
number of observations in this analysis is 338 (26 × 13).
Data on various fiscal variables are extracted from State Finances: A Study of Budgets of
2019–20, RBI, while state-wise GSDP (real and nominal) is from the Ministry of Statistics
and Programme Implementation. We have used two specifications of the standard fiscal
policy response function, discussed below:
MACROECONOMICS AND FINANCE IN EMERGING MARKET ECONOMIES 13
Specification 1
Specification 2
where PB represents primary balance to GSDP ratio; D is debt to GSDP ratio; Output gap
signifies the difference between the real output and the potential real output; RR
represents revenue receipts to GSDP ratio; ε is error term; and AD is augmented debt to
GSDP ratio.
This study analyses two variants of the principal explanatory variable debt wherein
Specification 1 (equation 6) assesses the sustainability of conventional debt ‘D’, while
Specification 2 (equation 7) is beyond estimating conventional debt sustainability and so
incorporates off-budget liabilities in the form of outstanding guarantees issued to SPSEs.
This new principal variable is referred to as augmented debt ‘AD’ in this study. Further,
under Specification 2, two scenarios are considered based on how much of guarantees
could be risky. As pointed out in the 2004 RBI paper, a realistic scenario could be to take
a certain proportion. However, the lack of transparency makes assessing fiscal risk due to
guarantees extremely challenging necessitating the use of certain proportion based on
reasonable parameters (Reserve Bank of India (RBI) 2002). Accordingly, as a rule of thumb,
converting guarantees into debt using a factor of 1/3 was adopted in some earlier papers
(Thorat and Roy 2004).
The RBI committee Report (2004) clearly mentions that the highest amount of default is
in power sector, necessitating a need to monitor power-sector guarantees closely. Since
then, however, a lot of structural changes have happened. Share of power-sector guar
antees has risen from about 40% to 70%, on an average, with some states at 80%. Under
such a situation, adding the share of power-sector guarantees (70%) to conventional debt
to get the augmented debt is the most apt to highlight the fiscal risks coming from this
angle. The likelihood of power-sector guarantees getting crystallized is probable from
both precedence and performance point of view. During the last 13 years, on three
occasions, the Government has tried to support power-sector SPSEs. Under UDAY, almost
the majority of power-sector debt was added to states’ debt and the impact is still being
felt by many (Reserve Bank of India (RBI) 2019a). In terms of performance, most of them
are still running losses, with talk of another restructuring required. In such a situation, it
would be prudent to add the power-sector guarantees to conventional debt in order to
arrive at the augmented debt and to highlight fiscal risks. While this remain one scenario,
the alternate scenario which assumes the proportion at 100% represents an extreme
situation – as not all guarantees will be invoked at the same time – keeping this scenario
helps to understand the maximum fiscal risks posed by these off-budget liabilities. This is
important in the context of the global debate on adopting a public sector balance sheet
approach (International Monetary Fund (IMF) 2018) and also considering the fact that
some Latin American countries have started including state-owned enterprises in their
fiscal targets.
14 S. MISRA ET AL.
The coefficient ‘β’ is the key to estimating the response of primary balance to debt as
per Specification 1 and, likewise, augmented debt as per Specification 2. A positive
coefficient lying between zero and one depicts the sustainability of public debt. While
a negative β coefficient indicates the unsustainability of public debt. Two control vari
ables, namely the real output gap and revenue receipts (RR), are employed in line with
Ostry and Abiad (2005).
The real output gap is measured as the difference between the actual real GSDP and
the potential real GSDP wherein the latter is estimated using the Hodrick–Prescott (HP)
filter. A positive coefficient of the output gap (actual output is above the potential output)
indicates that primary balance improves when real GSDP is above the potential and
therefore surplus rises in response to cyclical effects on revenues and expenditures.
The other control variable RR allows us to distinguish fiscal structures amongst states.
Given the weak revenue-raising capacity amongst the majority of Indian states, more so
after the implementation of GST, the use of revenue receipts to GSDP can be considered
as a direct proxy for states’ surplus generating capacity, particularly considering that few
states have higher revenue-generating capacities than others. Hence, RR is illustrative of
robust fiscal capability.
Furthermore, to underpin the empirical results, we conducted a robustness check by
using the revenue receipts gap and the average of RR to GSDP ratio over the previous two
years, rather than contemporaneous revenue receipts to GSDP ratio. Further, the other
control variable – primary expenditure gap – which is the difference between the actual
primary expenditure16 and the trend primary expenditure capturing deviations in primary
expenditure from long-term trend, is also considered. Higher primary expenditure from
the trend signifies deterioration in primary balance.
Empirical results
Indicator-based approach
A quick assessment of the ability of state governments to service and repay the debt
through current sources of income is conducted using an indicator-based approach. By
dividing the entire post-reform period 1992–93 to 2018–19 into different phases based on
the fiscal performance of states and by analysing the debt sustainability indicators of all
the states together, we found that the real rate of interest is lower than the real GDP
growth rate in all phases, thus fulfiling the necessary condition for debt sustainability
(Table 4).17 However, the GDP growth-interest rate differential has narrowed down in the
last five years, necessitating the need for larger and faster corrections in primary deficits
for debt to be in a sustainable path (Chart 7). Furthermore, the primary balance has
remained consistently negative (implying primary deficits) throughout all phases (except
Phase III), consequently violating the sufficient condition of debt sustainability (Table 4).
The last phase (2015–16 to 2018–19), coinciding with the issuance of UDAY bonds,
witnessed the highest primary deficit in the post-FRBM period.
The declining (r-g) coupled with a rising primary deficit hint at the fast-shrinking
window for debt sustainability. The next indicator, i.e., interest payments to revenue
receipts ratio, is essentially a debt servicing indicator reflecting how much of the revenue
receipts go towards financing interest payments. Notwithstanding a decline in this ratio

over the phases, the ratio is still higher than the tolerable limit of 10% as prescribed by the
Fourteenth Finance Commission (FC-XIV). Lastly, while debt was growing at a rate lower
than the nominal GDP growth in the post-FRL phases, in the latest post-UDAY phase, the
rate of growth of debt stood higher than the growth rate of nominal output signalling
potential debt sustainability risks. The ambivalence in this indicator-based approach of
debt sustainability demands further investigation of the solvency of state governments.

to be a fallout of realizations of contingent liabilities under UDAY.

test assumes a common unit root across cross-sections, while the Im–Pesaran–Shin (IPS)
and Fisher–ADF assume individual unit root processes. Here, the null signifies the pre
sence of a unit root at level, while its rejection ascertains that the data series is stationary.
The results of all the panel unit root tests are presented in Table 5, and these three tests
unanimously suggest that all the variables are stationary at level.
After ensuring the stationary properties of data, the fiscal policy response function is
measured using the panel estimation methods. The Hausman specification test validates
the random-effects model. A diagnostic check revealed the presence of heteroscedasti
city, though the model did not suffer from autocorrelation and cross-section dependence
of residuals, something typical of macro panels with long time series. Consequently, the
FGLS model is also applied as it deals with heteroscedasticity. Empirical results of alternate
models described above are summarized in Table 6.18
Model 1 (that uses random effects) gives a negative and statistically significant β
coefficient at 1% level, while Model 2 (that corrects for heteroscedasticity using FGLS)
offers a statistically insignificant β coefficient, thus rejecting the null of unsustainability of
states’ debt. These results may signify weak evidence with regard to the sustainability of
states’ debt. However, with the inclusion of all guarantees (referred to as augmented debt
under Scenario 1), debt clearly moves into the unsustainable path as shown under both
Model 3 and Model 4. This suggests that the primary balances in India respond negatively
to increases in augmented debt, indicating that the debt sustainability condition for an
intertemporal budget constraint is not satisfied. We have also considered a slightly more
likely Scenario 2 (see Models 5 and 6), when a part of guarantees, particularly those in the
power sector, is invoked, which also further confirms the likely unsustainability of states’
debt. Thus, this paper supports the argument that primary fiscal balances of subnational
governments in India respond in a destabilizing manner if the debt is considered in the
augmented form (inclusive of guarantees).19
The control variable (revenue receipts) is correctly positively signed and statistically
significant at 1% level, signifying that higher revenue generation helps to improve
primary balances. This also allows to distinguish fiscal structures amongst states, as
some states have higher revenue-generating capacities compared with others. Further,
a positive and significant coefficient of output gap indicates that primary balances
improve in response to cyclical effects, particularly due to the impact on states’ own
revenues and central transfers.
These empirical results are broadly robust to various alternative specifications, as
provided in Appendix Table A1. Alternate specifications are based on different control
variables such as revenue receipts gap, primary expenditure gap and average revenue
receipts with debt and augmented debt (obtained by adding only power sector out
standing guarantees, about 70% of the total, to outstanding liabilities, which is a more
likely scenario) as prime independent variables under both RE and FGLS model specifica
tions. It is observed that broadly the sign and significance of debt and augmented debt
are retained. In general, as we move from debt to augmented debt liabilities, the β
coefficient indicates that debt moves from sustainable to unsustainable ranges or, if
already unsustainable, the strength and significance of the coefficient increases. In the
case of a control variable, the output gap loses its significance. These results are robust to
the inclusion of time and fixed effects in the regression. These robustness checks further
buttress the empirical results of this study and hence reconfirm the augmented debt
unsustainability concerns of the states in the long run.
off of unpaid subsidies, if any, by the state governments; and, charging guarantee fees to
avoid any kind of moral hazard on the one hand, and also to add to revenues of the states,
on the other.
Notes
1. States’ market borrowings have more than doubled in the last 5 years.
2. Under the OTS of 2003, the outstanding dues of the State Electricity Boards to the central
public sector undertakings were taken over by the state governments through the issuance
of power bonds (with SLR status) amounting to ₹29,606 crores. The FRP 2012 restructured the
debt of 7 state power distribution companies (DISCOMs) by taking over 50% of their out
standing short-term debt obligations up to 31 March 2012. Under UDAY, the states took over
75% of the DISCOMs’ debt, through the issuance of non-SLR UDAY bonds and transferred the
proceeds to DISCOMs. A total of 16 states issued bonds under UDAY in 2015–16 and 2016–17,
leading to a sharp rise in these states’ debt, interest payments and redemption pressures.
3. Due to data constraints on guarantees, the analysis in the paper has been restricted until 2017–18.
4. Since the Fourteenth Finance Commission (FC-XIV) found the differentiation between special
category state and non-special category state redundant, we have considered all states in our
study.
5. In this study, subnational debt refers to the debt of the state governments only, local bodies’
debt is not included due to its unavailability.
6. BRICS is the acronym coined for an association of five major emerging national economies:
Brazil, Russia, India, China, and South Africa.
7. Article 293 of the Indian Constitution puts a restriction on overall borrowings by states that
are sanctioned by the Centre till the time the previous loan provided by the central govern
ment is outstanding. Additionally, SPSEs are allowed to raise off-budget borrowings along
with guarantees which are provided by states under Article 293 (1) of the Constitution.
8. A state-wise time series on guarantees outstanding can be culled out from RBI’s annual
publication State Finances: A Study of Budgets of 2019–20 (Reserve Bank of India (RBI) 2019a)
under Statement 28.
9. At end-March 2019, guarantees’ data are available for only 11 states and amounted to 0.8% of
GDP. Using the same states’ data for the previous year, outstanding guarantees amounted to
0.6% of GDP, clearly exhibiting a rise in guarantees issued in 2018–19.
10. It is clarified that once guarantees fall on states debt, to that extent guarantees get reduced.
For example, state guarantees which increased significantly prior to 2014, fell sharply there
after, primarily driven by subsuming of 75% of powers sector guarantees into state govern
ment liabilities as part of UDAY scheme. After a decline for few years, again guarantees, more
so in power sector, started rising from 2017–18 reflecting fresh net accretion of guarantees
with additional fiscal risks.
11. In practise, equation (4) can also be modified toΔ bt = bt-1(rt – gt)/ (1 + gt) – pbt + ddatwhere
ddat refers to deficit-debt adjustment as a share of GDP comprising factors that affect debt but are
not included in budget balance (Bouabdullah et al. 2017; Jaramillo, Mulas-Granados, and Kimani
2017). With ddat = 0, stability conditions as stated above remain the same.
12. It may be noted that Buiter and Patel (1992) is the only previous study that has assessed the
debt sustainability for Centre, states, and PSUs together. It finds the discounted debt series –
using various alternative measures of interest rates – to be non-stationary and hence
unsustainable. The study though remains significantly dated.
13. The current sources of revenue should not include any temporary revenues/grants or capital
receipts emanating from the sale of assets.
14. To avoid the endogeneity issue, Dt is replaced by Dt-1.
15. The P-value of chi-square statistic being greater than 5%, any deviation is due to chance
alone 5% of the time or less and hence the random effect model is appropriate.
16. Primary Expenditure = Total Expenditure – Interest Payments.
