Household Credit Global Financial Cycle And Macroprudential Policies

We analyze the effects of macroprudential policies on local bank credit cycles and interactions with international financial conditions. For identification, we exploit the comprehensive credit register containing all bank loans to individuals in Romania, a small open economy subject to external shocks, and the period 2004-2012, which covers a full boom-bust credit cycle when a wide range of macroprudential measures were deployed. Although household leverage is known to be a key driver of financial crises, to our knowledge this is the first paper that employs a household credit register to study leverage and macroprudential policies over a full economic cycle. Our results show that tighter macroprudential conditions are associated with a significant decline in household credit, with substantially stronger effects for foreign currency (FX) loans than for local currency loans. The effects on FX loans are higher for: (i) ex-ante riskier borrowers proxied by higher debt-service-toincome ratios and (ii) banks with greater exposure to foreign funding. Moreover, tighter macroprudential policy has stronger dampening effects on FX lending when global risk appetite is high and foreign monetary policy is expansionary. Finally, quantitative effects are in general larger for borrower rather than lender macroprudential policies.

Using a recent IMF survey and expanding on previous studies, we document the use of macroprudential policies for 119 countries over the 2000-13 period, covering many instruments. Emerging economies use macroprudential policies most frequently, especially foreign exchange related ones, while advanced countries use borrower-based policies more. Usage is generally associated with lower growth in credit, notably in household credit. Effects are less in financially more developed and open economies, however, and usage comes with greater cross-border borrowing, suggesting some avoidance. And while macroprudential policies can help manage financial cycles, they work less well in busts.

Abstract In this paper we ask whether countries can influence their exposure to changes in global financial conditions. Specifically, we show that even though we can model cross-country capital flows via a global factor that closely tracks changes in global financial conditions, there is a large degree of heterogeneity in the sensitivity of each country to this same global factor. We then evaluate whether this cross-country heterogeneity can be attributed to different policy choices, including measures of capital flow management, such as capital controls and macroprudential policies. In our main results, we show that higher levels of capital controls and macroprudential policies both dampen the sensitivity to the global factor. Furthermore, we show that countries’ monetary and exchange rate policies can also be successfully deployed. Overall, our results have implications that extend beyond the surge that preceded the 2008 global financial crisis, and that closely resonate in light of the financial disruptions that followed the COVID-19 pandemic.

The countercyclical capital buffer (CCB) was proposed by the Basel committee to increase the resilience of the banking sector to negative shocks. The interactions between banking sector losses and the real economy highlight the importance of building a capital buffer in periods when systemic risks are rising. Basel III introduces a framework for a time-varying capital buffer on top of the minimum capital requirement and another time-invariant buffer (the conservation buffer). The CCB aims to make banks more resilient against imbalances in credit markets and thereby enhance medium-term prospects of the economy—in good times when system-wide risks are growing, the regulators could impose the CCB which would help the banks to withstand losses in bad times.

We study the role that changes in credit and fiscal positions play in explaining current account fluctuations. Empirically, the current account declines when credit increases, and when the fiscal balance declines. We use a two-country model with financial frictions and fiscal policy to study these facts. We estimate the model using annual data for the U.S. and “a rest of the world” aggregate that includes main advanced economies. We find that about 30 percent of U.S. current account balance fluctuations are due to domestic credit shocks, while fiscal shocks explain about 14 percent. We evaluate simple macroprudential policy rules and show that they help reduce global imbalances. By taming the financial cycle, macroprudential rules that react to domestic credit conditions or to domestic house prices would have led to a smaller and less volatile U.S. current account deficit. We also show that a countercylical fiscal policy rule that stabilizes output growth reduces the level and volatility of the U.S. current account deficit.

This paper introduces a new comprehensive database of macroprudential policies, which combines information from various sources and covers 134 countries from January 1990 to December 2016. Using these data, we first confirm that loan-targeted instruments have a significant impact on household credit, and a milder, dampening effect on consumption. Next, we exploit novel numerical information on loan-to-value (LTV) limits using a propensity-score-based method to address endogeneity concerns. The results point to economically significant and nonlinear effects, with a declining impact for larger tightening measures. Moreover, the initial LTV level appears to matter; when LTV limits are already tight, the effects of additional tightening on credit is dampened while those on consumption are strengthened.

The crisis has underscored the costs of systemic instability at both the national and the global levels and highlighted the need for dedicated macroprudential policies to achieve financial stability. Building on recent advances, this paper provides a framework to inform the IMF’s country-specific advice on macroprudential policy. It recognizes that developing macroprudential policy is a work in progress, and addresses key issues to help ensure its effectiveness.

This paper provides background material to support the Board paper on the interaction of monetary and macroprudential policies. It analyzes the scope for and evidence on interactions between monetary and macroprudential policies. It first reviews a recent conceptual literature on interactive effects that arise when both macroprudential and monetary policy are employed. It goes on to explore the “side effects” of monetary policy on financial stability and their implications for macroprudential policy. It finally addresses the strength of possible effects of macroprudential policies on output and price stability, and draws out implications for the conduct of monetary policy.
