Abstract
We use micro–level data to analyze emerging markets’ privatesector access to international
debt markets during s overeign debt crises. Using fixed effect analysis, we find that these crises
are systematically accompanied by a decline in foreign credit domestic private firms, both during
debt renegotiations and for over two years after the restructuring agreements are reached. This
decline is large (over 20 percent), statistically significant, and robust when we control for a
host of fundamentals. We find that this effect is concentrated in the nonfinancial sectorand is
different for exporters and for firms in the non–exporting sector. We also find that the magnitude
of the effect depends on the type of debt restructuring agreement.

1 Introduction
In the last two decades of the 20th century, emerging markets experienced a lending boom. Not
surprisingly, this boom was accompanied by a number of sovereigndebt restructuring episodes,
many of which were followe d by economic crises of varying severity in the affected countries. One
channel through which economic activity can be affected by sovereigndebt restructuring is the
tightening of external financial constraints for theprivate firms. This may be an important channel,
because international capital market has become an important source of funds for the emerging
markets’ private sector. Throughout the lending boom, privatesector borrowing accounted for
over 30% of total net capital inflows to emerging markets.
1
Now about 25% of emerging markets’
corporate bonds and bank credit are external, and this number is much larger for Latin American
emerging economies.
2
To our knowledge, this paper presents the first systematic analysis of the effects of sovereign
debt crises on the foreign credittotheprivate sector. Recent empirical work has found various
changes in privatesectorcredit patterns in the aftermath of financial crises (Blalock, Gertler,
and Levine, 2004; Desai, Foley, and Forbes, 2004; Eichengreen, Hale, and Mody, 2001; Tomz and
Wright, 2005) as well as changes in stock market behavior (Kallbe rg, Liu, and Pasquariello, 2002;
Pasquariello, 2005). The empirical literature regarding the effects of sovereigndebtcrises has
focused on the impact on sovereign borrowing.

We focus on the short- and medium–run effects of
sovereign debtcrises on private firms’ access to foreign credit. In our exercise, we do not estimate
the probability of sovereigndebt crises; instead, we take these events as given and analyze their ex

Eichengreen and Lindert (1989) find that sovereign default does not seem to influence future access of sovereigns
to the capital market. This finding is confirmed in a recent study by Gelos, Sahay, and Sandleris (2004) — they find
that the probability of the sovereign’s market access is not strongly influenced by thesovereign default. On the other
side of the debate, Ozler (1993) claims that the countries can only reenter thecredit market after settling old debts,
and Tomz and Wright (2005) find that over the last 200 years “about half of all defaults led to exclusion from capital
markets for a period of more than 12 years.”

post effects.
Debt restructuring is not a discrete event, but rather a proce ss that in many cases involves
a substantial period of time. Because it is possible that the response of both borrowing firms
and foreign investors is different during debt renegotiations than it is after the final restructuring
agreement, we construct data on the onset of debt renegotiations and consider separately the effects
of the renegotiations andthe effects of reaching the restructuring agreement. We also analyze the
effects of different types of debt restructuring agreements.
Sovereign debt crisis can lead to reduced foreign credittoprivate domestic firms via the
decline in supply, as lenders’ perceptions of country risk worsen (Drudi and Giordano, 2000), via
the decline in aggregate demand that is triggered by a sovereigndebt crisis and its resolution
(Dooley and Verma, 2003; Tomz and Wright, 2005), and via exogenous shocks that affect both
the probability of sovereigndebt crisis andthe amount of foreign credittotheprivate sector. We
provide an intuitive discussion of these channels. While our empirical methodology does not allow
us to distinguish between the demand andthe supply effects, we address the possibility of a common
shock.
Our micro–level data on foreign bond issuance and foreign syndicated bank loan contracts come
from Bondware and Loanware and cover 30 emerging markets between 1984 and 2004.
4
We group
privately owned firms into financial and nonfinancial sectors and split the latter into exporting and
non–exporting sectors using information on the export structure of the country.
5
For each sector,
we calculate the total amount that firms borrowed in the bond market or from bank syndicates
in each month. We also construct a number of indicators that describe various aspects of each
country’s economy as well as factors that affect the world supply of capital to emerging markets,
4
Hale (2007) shows that sovereigndebt restructuring has a large impact on the instrument composition of private
borrowers’ external debt. Thus, we are combining bond and bank financing to account for possible substitution
between the instruments.
5
We attempted to split our sample according to an industry’s financial dependence (Rajan and Zingales, 1998).
Unfortunately, financial dependence data are available only for the manufacturing sector, which will make us lose
more than a half of our sample.

which we use as control variables. We analyze these data using fixed effects panel regressions.
We find systematic evidence of a decline in foreign credit in the aftermath of sovereign debt
crises.
6
All the effects are statistically significant and economically imp ortant: After controlling
for the effects of fundamentals, we find an additional decline in credit of over 20% below the
country–spec ific average during thedebt renegotiations, which persists more than two years after
the restructuring agreement is reached. In our analysis of different types of debt restructuring
agreements, we find that the decline in foreign credittotheprivatesector is smaller after agreements
with commercial creditors as opposed to agreements with official creditors and that no decline occurs
after voluntary debt swaps anddebt buybacks. Furthermore, agreements that include new lending
lead to a lower decline in credittotheprivatesector than agreements that do not.
The distribution of this decline is uneven across firms: Credittothe exporting sector is not
affected during thedebt renegotiations but declines after the agreement is reached, while credit to
the non–exporting sector declines during the renegotiations and then recovers within a year after
the agreement is reached; credittothe financial firms also declines after the agreement is reached
but by a small amount that is not statistically different from zero. Our tentative explanation for
these findings is an information story in which lenders have different amounts of information about
different types of borrowers and engage in relationship lending.
7
It is worth emphasizing that in focusing on foreign debt financing of emerging market pri-
vate firms, we do not analyze capital flows that occur in the form of trade credit, foreign direct
investment (FDI), or funds raised on the stock market.
8
We also exclude multinational and foreign–
owned companies from our sample. Thus, our results are limited to foreign borrowing by private

In order to capture country risk premium properly, we exclude from the analysis all foreign owned firms.

Glennon, and Nigro (2006) and references therein.

Auguste, Dominguez, Kamil, and Tesar (2006) show that after the most recent crisis in Argentina, firms suc-
cessfully raised funds through ADRs. In a systematic analysis Arslanalp and Henry (2005) find that when countries

domestically owned firms.
Our findings represent a step towards understanding the costs of sovereigndebt crises. Recent
models of financial crises in general anddebtcrises in particular assume that debtcrises are costly,
particularly in terms of cost of capital (Arellano, 2004; Arellano and Ramanarayanan, 2006; Yue,
2005), but there is very little empirical evidence on the nature of these costs.
9
Our paper provides
a justification for the assumption of costly debtcrises as well as and a set of observations that
might facilitate explicit modeling of such costs.
The remainder of the paper is organized as follows. In Part 2 we discuss the channels through
which sovereigndebtcrises can affect private firms’ foreign borrowing. Part 3 describes the empirical
approach andthe data. Part 4 presents the results of the empirical analysis and their relation to
the mechanism of the transmission of debt crisis effects totheprivate external borrowing. Part 5
concludes.
2 Sovereigndebtcrisesand lending totheprivate sector
In this section we provide an intuitive discussion of the channels through which sovereigndebt crises
can affect foreign creditto domestically owned private firms. We focus on the short–run effects
and do not discuss structural changes in the economy, such as entry or exit in certain sectors, or
fire–sale FDI activity.
2.1 Causal effects
When thesovereign starts debt renegotiations, whether or not it formally announces its inability to
service the debt, investors might perceive the country risk to be higher and raise the risk premium

Yue (2006).

they charge all the borrowers from the country (Drudi and Giordano, 2000). In fact, in many cases
credit rating agencies follow a “sovereign ceiling” practice, according to which no private borrowers
can obtain a better rating than their sovereign. Thus, credit would become m ore e xpensive for all
domestic firms and firms would decrease their borrowing.
10
The size of the decline in credit will
depend on the price elasticity of demand for credit. One would expect that financial and exporting
sectors would be more responsive tothe changes in the cost of credit: financial firms can rely
on domestic liabilities such as deposits or can reduce their lending, while e xporters can finance
themselves through trade credit.
There is, however, a possibility of an offsetting effect. When a sovereign starts renegotiations
of the debt, it is unlikely to be able to issue any new debt until the deal is settled. During this
time investors might want to lend tothe country for diversification reasons and thus might actually
increase their supply of credittotheprivate sector.
After the restructuring agreement is reached, the period of recovery from thedebt crisis starts.
Depending on the terms of the agreement, the country risk premium might fall or rise compared
to what it was during the renegotiation period: on the one hand, the uncertainty regarding the
terms of restructuring is resolved, which will always lead to a decline in the risk premium, ceteris
paribus; on the other hand, the terms of the agreement could change investors’ assessment of the
probability of future debtcrisesand of their losses in case the crisis occurs. If the “haircut” (or
the reduction in the present value of the debt) is too high, investors would expect higher losses
in the future, and if the haircut is too low, they will expect that thesovereign will again have
problems servicing its debt. In either case, the country risk premium might actually go up after
the agreement is reached,
11
and the amount of credit will decline even further.
In practice, sovereigndebtcrises are frequently accompanied by a decline in aggregate demand
10
The empirical literature shows that foreign debt restructuring by a sovereign may lead to persistent worsening of
the terms of future borrowing for all ownership sectors (Hale, 2007; Ozler, 1993; Tomz and Wright, 2005).

details of debt restructuring episodes.

(Dooley and Verma, 2003; Tomz and Wright, 2005). This could be due to a current or expected
monetary and fiscal tightening, tothe conditionality that IMF involvement in the crisis resolution
usually carries, or to an exogenous shock that leads to both sovereigndebtcrisesandto a dec line
in aggregate demand. We discuss the latter possibility in the next section.
Whatever the mechanism, the decline in aggregate demand may lead to a decline in the demand
for goods and services, especially for firms in the non–exporting sector.
12
This decline in demand
will lead to two effects: First, firms are likely to experience a decline in profits that would lead to a
decline in their net worth, which, in thecredit rationing environment, will tighten their borrowing
constraints.
13
Second, the firms are likely to ac cumulate inventory and produce less next period,
which means they will demand less credit. They will also use fewer inputs, which will push the
price of inputs down and lower the input costs, and therefore further lower their demand for credit.
Sovereign debtcrises are frequently accompanied by domestic banking crises, usually because
the government postpones debt restructuring talks and strains the banking system in order to
service thedebt until doing so is no longer feasible. This would make domestic liquidity more scarce
and would increase demand for foreign credit both from the banking system and from nonfinancial
firms that find it difficult to borrow domestically.
14
Some sovereigndebtcrises are also accompanied by currency collapses. Abstracting from the
long–run effects of these currency collapses, we focus on the accounting effect of large changes
12
Since there is no evidence of direct trade sanctions imposed in the aftermath of sovereign defaults (Martinez and
Sandleris, 2004), the decline in demand for the exports is less likely to occur. Rose (2005), on the other hand, finds
that, in the long run, debt renegotiations do lead to a decline in trade. In addition, as Helpman (2006) p oints out,
firms that export only export a small fraction of their output, and, therefore are also likely to be affected by a decline
in domestic aggregate demand.
13
Sandleris (2005) derives these effects in a context of endogenous sovereign default. See Stiglitz and Weiss (1981),
Calomiris and Hubbard (1990), and Mason (1998) for models of credit rationing and net worth. See Arellano, Bai,
and Zhang (2006), Mendoza (2006) and Schneider and Tornell (2004) for the models of borrowing constraints in the
context of financial crisis.

(2002).

in the real exchange rates.
15
First, if most of the firms’ costs are denominated in the domestic
currency, they will have to borrow less in foreign currency in order to obtain the same amount in
domestic currency. Since most foreign lending is denominated in “hard” currencies (Eichengreen
and Hausmann, 1999; Eichengreen, Hausmann, and Panizza, 2002), this would mean a decline in
demand for foreign credit. In addition, exporting firms will experience a decline in their domestic
input costs relative to their foreign sales (which are denominated in foreign currency (Goldberg
and Tille, 2005)). This decline would lead to an increase in their profits and retained earnings and
would allow them to borrow less, i.e., demand less credit. On the other hand, domestic firms that
use imported intermediate goods will experience an increase in their input costs and will therefore
demand more credit. Finally, firms with liabilities denominated in foreign currencies that sell in
domestic markets will experience balance sheet effects, which would immediately lead to a decline
in their net worth and tighten their borrowing constraints. Thus, currency depreciation would also
lead to a decline in the supply of creditto non–exporting firms.
Thus, a sovereigndebt crisis can lead to a decline in foreign credittotheprivatesector through
both a decline in the supply of creditand through a decline in the demand for credit. In this paper,
due to data limitations, we do not attempt to disentangle the demand andthe supply effects, but
rather estimate a reduced form model of the effects of sovereigndebtcrises on the amount of foreign
credit obtained by privatesector firms. However, we try to isolate some of the channels discussed
above by controlling for the state of the economy (through a set of indexes), for the presence of the
IMF agreement, for banking crises, and for changes in real exchange rate.
15
Burstein, Eichenbaum, and Rebelo (2002) and (2004) show that domestic prices adjust very slowly after a currency
collapses, and, therefore, real and nominal exchange rates move closely together in the short run.

2.2 Common shocks
A decline in foreign credittotheprivatesector could also be due to a shock that simultaneously
triggers a sovereigndebt crisis.
16
For example, an adverse aggregate demand or productivity shock
would decrease theprivate sector’s demand for credit, as described above, and at the same time
lead to a decline in government revenues and therefore to a sovereigndebt crisis.
Furthermore, both a sovereigndebt crisis and a decline in credittotheprivatesector could
result from a sudden stop in foreign capital inflows into the country (Calvo, 1998). In this case,
the decline in credittotheprivatesector would b e due to a decline in the supply of creditto the
country as a whole, rather than to a decline in a demand for credit by individual private firms.
In both cases, a common shock would create an association between debt renegotiations and
foreign credittotheprivate s ec tor. It is unlikely, however, that a common shock would lead to the
same simultaneity problem between the restructuring agreement andthe foreign creditto private
sector, since the timing of the restructuring agreement depends predominantly on the renegotiation
progress.
Since we are interested in the causal relationship between sovereigndebtcrisesand foreign
credit toprivate sector, we do our best to control for common shocks in two ways: first, including
a set of aggregate demand variables (collected into indexes) andthe indicator for systemic sudden
stops (Calvo, Izquierdo, and Talvi, 2006) as control variables in our fixed effects regressions;
17
and,
second, using treatment effects methodology, described in Section 4.4.
16
See Aguiar and Gopinath (2006), Arellano (2004), and Yue (2005) for models of sovereign default due to an
exogenous adverse shock. They also show that the same shock leads to a de cline in the country’s borrowing, although
they do not distinguish between theprivateandthe public sectors.
17
Due tothe potential endogeneity of the sudden stop variable, we do not include it in our main specification, but
analyze its effect in our robustness tests. The results of the main specification are not affected by the addition of the
systemic sudden stop control variable.

debt crises on the foreign credit to the private sector. Recent empirical work has found various
