Global crisis

Following the Global Crisis, countries have significantly increased their efforts to cooperate on bank supervision, the prime example being the euro area’s Single Supervisory Mechanism. However, little is known about whether such cooperation helps improve the stability of the financial system. Using panel data for a large sample of cross-border banks, this column examines whether a higher incidence of supervisory cooperation is associated with higher bank stability. It finds that supervisory cooperation is effective, working through asset risk, but not for very large banks, which are the ones that pose the highest risk to financial stability.

The increased post-Global Crisis monitoring of house prices still lacks an effective measure for cross-country comparisons. This column outlines the creation of an integrated database covering advanced and emerging economies on the price per square metre of housing. The model shows that price-to-income ratios vary substantially at the extremes, but that the majority economies converge around the median level. Country rankings based on housing prices in euros versus PPP also vary significantly.

During the Global Crisis, international trade decreased more than overall economic activity, despite standard trade models predicting a one-to-one relationship. This ‘Great Trade Collapse’ has been investigated extensively in the literature, resulting in alternative competing explanations. This column evaluates the contribution of each story using data from the US. The results show that retail inventories have contributed the most to the collapse and the corresponding recovery, followed by protectionist policies, intermediate-input trade, and trade finance. Productivity and demand shocks have played negligible roles.

Externalities can have a powerful effect on financial stability. This column studies the amplification effect that can operate despite value at risk regulation, which suffers from the ‘fallacy of composition’. It shows that the magnitudes of booms and busts are amplified by two significant externalities triggered by aggregate shocks: the endogeneity of bank equity due to mark-to-market accounting and of bank liquidity due to 'fire-sales' of securitised assets. In addition to economic models, legal and political factors should also be considered.

Countries have significantly increased their public-sector borrowing since the Global Crisis. This column documents several potential fiscal dominance effects during 2000-17 under inflation targeting and non-inflation-targeting regimes. A higher ratio of public debt to GDP is associated with lower policy interest rates in advanced economies. In emerging economies under non-inflation-targeting regimes, composed mostly of exchange-rate targeters, the interest rate effect of higher public debt is non-linear and depends both on the ratio of foreign currency to local currency debt, and on the ratio of hard currency debt to GDP.
