Measuring financial stress in transition economies

Journal of Financial Stability 2013 9(4), 597-611 open access
This study constructs a financial stress index for Bulgaria, the Czech Republic, Hungary, Poland, and Russia and examines the relationship between financial stress and economic activity. The financial stress index incorporates banking sector fragility, time varying stock market return volatility, sovereign debt spreads, an exchange market pressure index, and trade credit. These variables seem to capture key aspects of financial stress in sample countries as the index peaks at known financial crises in these countries. We then examine the relationship between financial stress and economic activity. Impulse response functions based on bivariate VARs show a significant relationship between financial stress and some measures of economic activity. Overall, the constructed financial stress index provides valuable information on the state of the economy and economic activity.

How do IMF announcements affect financial markets in crises?

Journal of Financial Stability 2008 4(2), 121-134
We employ a theoretical model to interpret the liquidity and moral hazard effects of IMF support during a financial crisis. We then estimate the response of forward exchange markets to IMF-related announcements, using data on the 3-, 9-, and 12-month forward exchange rates. Our results indicate that the announcement of IMF negotiations is associated with a premium on the baht and the rupiah, where the premium is much larger on the latter. This result is largely consistent with the responses of stock and bond markets, especially when country-specific data are employed.

IMF programs, financial and real sector performance, and the Asian crisis

Journal of Banking & Finance 2012 36(1), 164-182
This paper has three objectives. First, using a richer and more comprehensive set of IMF-related news than previous studies, we examine the impact of IMF-related news on both financial and real stock sector returns in Indonesia during the Asian crisis. Second, we draw lessons about financial and real sectoral patterns of adjustment in crisis countries, including whether and how IMF programs facilitate this adjustment. Third, we explore the interplay between IMF actions in crisis countries and the actions and responses of local authorities. To do so, not only do we account for the impact of news regarding IMF policy actions but also the government’s reaction to them and willingness to implement such policies, and the public sentiment about the implemented IMF programs and government policies. We discuss the policy implications of the findings.

Is the evidence for PPP reliable? A sustainability examination of the stationarity of real exchange rates

Journal of Banking & Finance 2011 35(9), 2479-2490
Some recent time series studies testing the stationarity of real exchange rates (RERs) produce conflicting results. Using nonlinear unit root tests and recursive analysis, this paper tests whether the evidence on the stationarity of RERs is sensitive to different numeraire currencies, different sample periods covering regional and global crises, and the inclusion of countries with different levels of economic or regional integration. The results indicate that evidence for a stationary RER could be substantially sensitive to sample period changes, but not so for the currencies of the countries involved in forming the euro area. We also find that financial crises have a notable impact on testing the stationarity of RERs, depending on the numeraire currency used. We discuss the policy implications of the findings.

Financial stress transmission between the U.S. and the Euro Area

Journal of Financial Stability 2022 60, 101004
This paper examines financial stress transmission between the U.S. and the Euro Area. To better understand the linkages between financial stress in the two regions, we construct a financial stress index for the U.S. similar to the Composite Indicators of Systemic Stress (CISS) that has been developed for the Euro Area with a focus on systemic risk. Using weekly data from 2000 to 2021 and Granger predictability in distribution test, we analyze stress transmission in “normal” times as well as under unusually high and low stress episodes. While we document unilateral transmission from the U.S. to the Euro Area under normal conditions based on the center of the distribution, tail dependence tests and impulse response analysis show significant bilateral transmission, particularly in unusually high financial stress episodes. This holds true for aggregate indices as well as the subindicators of financial stress in various financial markets. As such, there must be global efforts to contain financial crises and ensure a strong and resilient financial system.

The reaction of asset prices to macroeconomic announcements in new EU markets: Evidence from intraday data

Journal of Financial Stability 2009 5(2), 199-219
We estimate the impact of macroeconomic news on composite stock returns in three emerging European Union financial markets (the Budapest BUX, Prague PX-50, and Warsaw WIG-20), using intraday data and macroeconomic announcements. Our contribution is twofold. We employ a larger set of macroeconomic data releases than used in previous studies and also use intraday data, an excess impact approach, and foreign news to provide more reliable inferences. Composite stock returns are computed based on 5-min intervals (ticks) and macroeconomic news are measured based on the deviations of the actual announcement values from their expectations. Overall, we find that all three new EU stock markets are subject to significant spillovers directly via the composite index returns from the EU, the U.S. and neighboring markets; Budapest exhibits the strongest spillover effect, followed by Warsaw and Prague. The Czech and Hungarian markets are also subject to spillovers indirectly through the transmission of macroeconomic news. The impact of EU-wide announcements is evidenced more in the case of Hungary, while the Czech market is more impacted by U.S. news. The Polish market is marginally affected by EU news. In addition, after decomposing pooled announcements, we show that the impact of multiple announcements is stronger than that of single news. Our results suggest that the impact of foreign macroeconomic announcements goes beyond the impact of the foreign stock markets on Central and Eastern European indices. We also discuss the implications of the findings for financial stability in the three emerging European markets.

The real effects of capital inflows in emerging markets

Journal of Banking & Finance 2020 119, 105933
We examine the association between capital inflows and industry growth in a sample of 22 emerging market economies from 1998 to 2010. We expect more external-finance-dependent industries, in countries that host more capital inflows, to grow disproportionately faster. This is indeed the case in the pre-crisis period of 1998–2007. In a panel regression analysis using annual changes, this relationship is driven by debt, rather than equity inflows. But when we consider the long-run effects using panel cointegration tests, equity inflows are those that contribute to growth. Further, we observe a reduction in output volatility, and this association is more pronounced for equity, rather than debt inflows. These relationships, however, break down during the crisis, indicating the importance of an undisrupted global financial system for emerging markets, if they are to harness the growth benefits of capital inflows. In line with this observation, we also document that the inflows-growth nexus is stronger in countries with well-functioning banks and better institutional quality.

Implications of bank ownership for the credit channel of monetary policy transmission: Evidence from India

Journal of Banking & Finance 2011 35(9), 2418-2428
Using bank-level data from India, we examine the impact of ownership on the reaction of banks to monetary policy, and also test whether the reaction of different types of banks to monetary policy changes is different in easy and tight policy regimes. Our results suggest that there are considerable differences in the reactions of different types of banks to monetary policy initiatives of the central bank, and that the bank lending channel of monetary policy is likely to be much more effective in a tight money period than in an easy money period. We also find differences in impact of monetary policy changes on less risky short-term and more risky medium-term lending. We discuss the policy implications of the findings.

Real and monetary convergence between the European Union’s core and recent member countries: A rolling cointegration approach

Journal of Banking & Finance 2005 29(1), 249-270
We use rolling cointegration to measure the convergence of base money, M2, the CPI and industrial output between Germany and France and recent EU members and some transition countries that are now joining the EU. Countries that joined the EU previously exhibit time-varying cointegration with the core countries over the 1980–2000 sample period. Cointegration for the transition economies was comparable for M2 and prices, but not for monetary policy and industrial output. Thus a peg to the Euro soon after accession is feasible for the East European countries, but the benefits of joining the Euro zone are as yet limited.

Non-performing loans, moral hazard and regulation of the Chinese commercial banking system

Journal of Banking & Finance 2016 63, 48-60 open access
Non-performing loans (NPLs) represent a major obstacle to the development of banking sector. One of the key objectives of the banking sector reforms in China has therefore been to reduce the high level of NPLs. To do so, Chinese regulatory authorities have injected significant capital into the banking system and scrutinized NPLs since 2003. This paper examines the impact of NPLs on bank behavior in China. Using a threshold panel regression model and a dataset covering 60 city commercial banks, 16 state-owned banks and joint-stock banks, and 11 rural commercial banks during 2006–2012, we test whether lending decisions of Chinese banks exhibit moral hazard. The results support the moral hazard hypothesis, suggesting that an increase in the NPLs ratio raises riskier lending, potentially causing further deterioration of the loan quality and financial system instability. Policy implications of findings are evaluated.
