Summary: Episodes of rapid credit growth, especially credit booms, tend to end abruptly, typically in the form of financial crises. This paper presents the findings of a comprehensive event study focusing on 99 credit booms. Loose monetary policy stances seem to have contributed to the build-up of credit booms across both advanced and emerging economies. In particular, domestic policy rates were below trend during the pre-peak phase of credit booms and likely fuelled macroeconomic and financial imbalances. For emerging economies, while credit booms are associated with episodes of large capital inflows, international interest rates (a proxy for global liquidity) are virtually flat during these periods. Therefore, although external factors such as global liquidity conditions matter, and possibly increasingly so over time, domestic factors (especially monetary policy) also appear to be important drivers of real credit growth across emerging economies. 


Executive Summary

This paper is motivated by rapid credit growth across many emerging economies, particularly those in Asia. It presents the results of a comprehensive event study which identifies 99 credit booms, of which 39 and 60 originated in advanced and emerging economies, respectively. Episodes of excessive credit growth—credit booms—lead to growing financial imbalances, and tend to end abruptly, often in the form of financial crises. In particular, relative to booms in other emerging economies, credit booms in emerging Asia were associated with a higher incidence of crises historically.

Three other main conclusions include the following:
  • First, as credit booms build, they are jointly associated with deteriorating bank and corporate balance sheet soundness, and symptoms of overheating including: large capital inflows (including less stable bank flows), widening current account deficits, buoyant asset prices, and strong domestic demand.
  • Second, while credit booms are associated with episodes of large capital inflows, international interest rates (a proxy for global liquidity), are virtually flat during these periods, which suggests the important role of domestic factors in driving credit growth across emerging economies. This may reflect, in part, that capital inflows are being channeled into other asset classes including real estate, equity, and corporate bonds, for example.
  • Third, loose macroeconomic policy stances seem to have contributed to the build-up of credit booms. In particular, this seems to be the case for monetary policy across both advanced and emerging economies. For emerging economies, while international interest rates were essentially flat, domestic policy rates were below trend during the pre-peak phase of credit booms. Therefore, although external factors such as global liquidity conditions matter, and possibly increasingly so over time, domestic factors (especially monetary policy) also appear to be important drivers of real credit growth across emerging economies including those in Asia.
