Episodes of financial turmoil that are characterized by stress in commercial and investment banks are more likely to be associated with severe and protracted downturns, according to new IMF research.

Published in an analytic chapter of the October 2008 World Economic Outlook, titled “Financial Stress and Economic Downturns,” the research shows that when financial stress hits core financial intermediaries, the downturns that follow are typically more severe than slowdowns or recessions not preceded by financial stress. In particular, slowdowns or recessions preceded by banking-related stress tend to involve 2–3 times greater cumulative output losses and tend to endure 2–4 times as long.

The chapter constructs an index of financial stress in banking, securities, and foreign exchange markets in 17 advanced economies over the past 30 years and identifies 113 episodes of financial stress. Of these, about one-half are identified as banking related, while in the remainder, the stress is mainly concentrated in securities and foreign exchange markets. Based on this metric, the current financial turmoil ranks as one of the most intense for the United States and one of the most widespread, affecting virtually all countries in the sample.

The research finds that not all episodes of financial stress are followed by a slowdown or a recession, and initial conditions are crucial. The degree to which house prices and aggregate credit have risen prior to the stress episode is associated with the likelihood of a sharper downturn. Moreover, while greater reliance on borrowing by firms is associated with a sharper downturn in the aftermath of financial stress, the size of financial imbalances in the household sector is crucial in determining whether the downturn will turn into a recession.

The research finds that financial innovation and the move toward more arms-length financial systems—where a greater share of intermediation is channeled through securities markets rather than traditional relationship-based banking—has not increased the likelihood of banking-related financial stress. But activity tends to be weaker in the recessions following banking stress in more arms-length financial systems.

A potential explanation for why banking stress in arms-length systems is associated with more severe slowdowns in activity is because of the procyclicality of leverage. Although the so-called twin engines of financial intermediation—banking and securities markets—could be expected to provide alternative channels of financing, the research finds that leverage tends to be more procyclical even in banks in more arms-length financial systems.

As a result, when a shock hits the system, deleveraging among banks is more abrupt in more arms-length financial systems, which may more adversely affect the availability of credit to the rest of the economy.

The chapter places the current episode of financial turmoil in historical context by comparing it to six well-known episodes of financial stress among advanced economies during the 1990s. These episodes related to Finland, Norway, Sweden, the United Kingdom, and the United States in the early 1990s, and Japan throughout the 1990s.

This comparison confirms the finding that the rapid buildup in credit and house prices and a heavier reliance on credit by firms and households were associated with a more severe economic downturn in the aftermath of banking distress.

Relative to these episodes of financial stress, the adjustments and imbalances in initial conditions thus far appear to be tracking previous stress episodes followed by recession along a number of dimensions. The deleveraging process of households in the United States is even proceeding faster than in typical past recessions, although that for corporates seems to have proceeded somewhat more slowly and, more important, from a stronger initial position.

More generally, corporate balance sheets and firms’ reliance on external financing were on a more solid footing entering into the current crisis, which should provide some resilience. But the sheer size of the U.S. mortgage market, which is at the heart of the current crisis, and the role of residential investment suggest that household saving and consumption behavior may play a much larger role in the current downturn than is typical.

On a positive note, the policy stance in the United States has been proactive, as exemplified by the aggressive cuts in policy rates and the measures taken to shore up liquidity in both the commercial and investment banking sectors, as well as ongoing initiatives to directly support the mortgage market.

For the euro area as a whole, the adjustment in house prices and credit has thus far been milder than in the United States, although recent evidence indicates the adjustment is gathering momentum. Firms are also starting from a stronger base in terms of their reliance on external financing.

The household sector’s position in the euro area is considerably stronger, and this is a distinguishing feature of financial stress episodes that are not followed by recessions. Although true for the euro area as a whole, there are important differences among countries.
