New experience for Europe

Motivation
• Strong impact of sovereign debt crisis on European financial system and real economy
• Consequences reach far beyond Europe’s borders
• “Sovereign debt crisis […] most immediate threat to global growth.” (IMF 2012)
• Real consequences through at least two channels
• trade linkages (consolidation of public finances weakening demand for imports)
• financial linkages (portfolio rebalancing by banks holding impaired sovereign bonds)
• Focus on latter
• effect of balance sheet exposure to impaired debt on domestic and foreign bank lending

This paper
• Study the impact of exposure to impaired foreign (GIIPS) sovereign debt on lending
• focus on banks active in the syndicated loan market
• 34 banks domiciled in 11 non-GIIPS European countries
• Specifically we study
• impact on total amount of loans extended
• change in composition of loan portfolios (domestic vs. foreign)
• interaction with banks’ “carry trade”-type behavior from first stage of the crisis
• Effect of ECB’s asset purchase program (SMP)
• Make sure results are not affected by:
• other types of shocks to banks’ balance sheets
• unobservable time-invariant bank characteristics
• Identification: heterogeneity in bank exposures, common borrower
• 1 affected and 1 non-affected bank lending to the same borrower at the same time

Why the syndicated loan market?
• Syndicated loan: a loan jointly extended by a syndicate of banks
• very large (median loan 150 mln. EUR)
• borrower can be a corporate, a bank, or a government entity
• World syndicated loan market important source of external finance for corporates
• 3.5 trillion EUR in 2007
• 250+ active banks
• 190+ borrower countries
• Accessibility and frequency
• publicly registered, covers all countries, universe of loans available (no sample selection concerns)
• available over long time period (1997 – this morning)
• Loan flows from individual banks to individual countries
• can exploit differences between banks w.r.t. to their exposure to impaired GIIPS debt
• can control for changes in credit demand and borrower quality

Sovereign debt on banks’ balance sheets
• Basel II / CRD gives banks incentives to hold government debt on their portfolios
• risk weight on debt issued in domestic currency allowed to be 0%
• exposure to highly rated sovereigns exempt from 25% limit on large exposures
• “By 2016, the conditions for a new systemic crisis - this time sovereign - might be in place. What is unique is that, while defaults on sovereign debt occurred before Basel I and II, this time regulatory authorities are actively encouraging banks to take refuge in government debt. So why is the Basel Committee insisting on calling local-currency-denominated sovereign debt risk-free? I don’t know.”
M. Pomerleano, Financial Times, February 3, 2010
• Euro area banks hold sizeable amounts of debt issued by foreign euro area sovereigns
• 1/3 of overall exposure
• perverse post-Lehman effect (flight to safety)
• European banking market makes for an ideal set-up
• banks hold simultaneously German Bunds and GIIPS debt
• varying degrees of exposure to safe and impaired debt
9
Link between sovereign debt and bank lending
• Exposure to foreign sovereign debt bank lending: two channels
• losses lead to weakening of the bank’s balance sheet and thus increase its riskiness
• adverse consequences for the cost and availability of funding
• sovereign debt often used as collateral
• reduced availability and eligibility of collateral, lower banks’ funding capacity
• Higher bank funding costs need to rebalance portfolio
• Increase in foreign sovereign debt risk reduction in supply of credit by banks
10
• Loan growth at “Affected” banks lower after 2010:Q3 (while higher before)
• Affected banks = banks with above-median exposure to GIIPS debt
Impact GIIPS sovereign debt exposure on bank lending
11
Preview of findings
• After 2010:Q3, affected banks increased lending less relative to non-affected banks
• by 23.5% in our preferred specification with bank and borrower-quarter fixed effects
• direct link between reduced creditworthiness of foreign sovereign debt and bank lending
• Reduction only in foreign lending (mostly US and GIIPS), domestic borrowers unaffected
• Results robust to alternating crisis period cut-offs and subsamples of host markets
• Tentative evidence that decline in lending has been arrested by:
• carry trade-type behavior by banks in 2010
• ECB’s asset purchase program in 2011

Contribution to the literature
• Transmission (domestic and cross-border) of bank funding shocks
• Kashyap and Stein (AER 2000); Peek and Rosengren (AER 2000); Jimenez et al. (AER 2010);
Cetorelli and Goldberg (IMF ER 2011); De Haas and Van Horen (AER 2012); Giannetti and
Laeven (JFE 2012); Popov and Udell (JIE 2012); Schnabl (JF 2012); Ongena et al. (2013)
• Shocks to bank balance sheets and syndicated lending
• Ivashina and Sharfstein (JFE 2010); Santos (RFS 2011); Giannetti and Laeven (JFE 2012); De
Haas and Van Horen (RFS 2013)
• we examine a novel channel of transmission (exposure to foreign sovereign debt)
• Linkages between sovereigns and banks
• Angeloni and Wolff (2012); De Bruyckere et al. (2012)
• we identify spillovers from foreign sovereign debt to credit supply
• Sovereign creditworthiness and credit availability
• Arteta and Hale (JIE 2008); Bofondi et al. (2012); Correa et al. (2012); Ivashina et al. (2012)
• we exploit differences with respect to balance sheet exposures in multi-country setting
• we study impact of foreign sovereign debt exposure on both foreign and domestic lending

• Diff-in-diff model:
• Lending: total syndicated loans issued by bank i to borrowers in country j during quarter t
• Post: dummy equal to 1 on and after 2010:Q4
• Affected: dummy equal to 1 if bank i is in top half of the sample in terms GIIPS exposure
• based on 2010:Q4 exposures
• Sample period: 2009:Q3 – 2011:Q4 (equal pre- and post- periods)
• Coefficient of interest:
• Captures change in lending from pre-treatment to post-treatment period
• for the group of affected banks relative to the group of non-affected banks
• If , lending increased less (decreased more) for the group of affected banks

• Diff-in-diff model:
• Bank balance sheet variables
• size, tier 1 ratio, share impaired loans, net income (1 year lagged)
• control for other types of shocks affecting concurrently bank’s balance sheets
• Bank fixed effects
• control for time-invariant bank-specific unobservable factors
• Country x quarter fixed effects
• control for (time-varying) changes in demand and borrower quality
• OLS, cluster by bank
Empirical methodology: Controls
15
• 90 European banks participating in EBA stress tests
• 4 waves: March 2010, December 2010, December 2011, June 2012
• EBA reports total holdings of sovereign debt issued by 30+ countries
• focus on debt issued by 5 GIIPS countries + domestic exposure
• Use 2010:Q4 data to calculate exposures (in ratio to assets)
• Different exposures in robustness tests
• Exclude GIIPS banks

• Degree to which bank i is exposed to GIIPS sovereign debt
• Affected: dummy variable equal to 1 if bank i is in top half of the sample

Comparison affected and non-affected banks
18
• Intersection of EBA and syndicated loans datasets (excluding GIIPS): 34 European
banks
• Domiciled in 11 non-GIIPS countries
• 71% of syndicated lending by European banks, 34% of total lending
• Unit of observation: bank – borrower country – quarter total lending
• For each loan all members known but often not exact loan shares
• split loan equally over syndicate member (De Haas and Van Horen AER 2012; RFS 2013)
• split 8108 syndicated loans in which at least one bank in our sample was active in 35295 loan portions
• use these loan portions to calculate quarterly (new) lending by bank i to country j

Main result
• Syndicated lending increased less for banks significantly exposed to impaired government
debt • economically large: lending increased 23.5 % less for affected banks in preferred specification
21
Accounting for alternative explanations
• (1) Results may be demand-driven
• low-net worth firms may borrow from low-net worth banks
• (2) Affected banks may be exposed to sovereign debt crisis in different ways
• exposure to own government
• government support with strings attached during financial crisis
• subject to different trends
• exposure to debt securities issued by GIIPS corporates
• higher share GIIPS customers
• loans in currencies that depreciated against euro (mechanical decline in lending)
• Solution to (1): country-industry-quarter FEs, repeated borrowers
• Solution to (2): condition on all alternative factors

Robustness
25
Robustness
• Results robust to: • measuring exposure earlier, as a share of equity, or continuously
• comparing more extreme exposures
• exposure to Greece only
• alternative ways of measuring lending
• alternative sample period lengths
• alternative sub-samples of banks
26
Portfolio reallocation
27
Portfolio reallocation
• Domestic and core European lending not affected
• Largest reallocation away from marginal, GIIPS, and US markets
28
Mechanisms affecting change in lending
• Banks did not immediately get rid of toxic debt when crisis started
• a number of (affected) banks in the sample increased GIIPS exposures between March and December 2010
• carry trade-type behavior by banks, hoping to pocket the spread between long-term bonds and short-term funding costs (Acharya and Steffen, 2012)
• effect on lending?
• ECB asset purchase program in late 2010 and 2011
• all but two banks in the sample decreased GIIPS exposures between December 2010 and December 2011
• most probably due to ECB’s asset purchase program
• effect on lending?

Change in exposure and lending
30
Change in exposure and lending
• Lower decline in lending for affected banks which increased exposures between March and
December 2010 (Optimists)
• Lower decline in lending for affected banks which decreased exposures more between
December 2010 and December 2011 (Big sale)
31
• We study impact of exposure to GIIPS sovereign debt on lending by non-GIIPS banks
• Our results suggest that
• foreign sovereign stress has sizeable impact on bank lending
• effect not driven by
• changes in borrower demand/quality
• time invariant bank characteristics
• other types of shocks that concurrently affect bank’s balance sheets
• effect strongest for lending to marginal, US, and GIIPS markets
• evidence for link between lending and carry trade/asset purchases
• Aggregate effect unclear (firms can switch between lenders or types of finance)
• Result may not be general (syndicated lending: large banks & large borrowers)
