Real effects of credit rating downgrades

Philippe Karam, Ouarda Merrouche, Moez Souissi, Rima Turk, 02 February 2015

In the wake of the Crisis, policymakers have introduced liquidity regulation to promote the resilience of banks and lower the social cost of crisis management. This column shows that a funding liquidity shock, manifested as lower access to wholesale sources of funding following a credit rating downgrade, translates into a significant decline in both domestic and foreign lending. Liquidity self-insurance by banks mitigates the impact of a credit rating downgrade on lending.

The two faces of cross-border banking flows

Dennis Reinhardt, Steven Riddiough, 07 May 2014

Cross-border funding between banks collapsed following the bankruptcy of Lehman Brothers, but the withdrawal of funding was not uniform across countries. This column argues that the composition of cross-border bank-to-bank funding can help to explain why. Interbank funding between unrelated banks is particularly vulnerable to global shocks, but intragroup funding between related banks can act as a stabilising force, particularly for advanced economies with a high share of global parent banks. Policymakers should look at disaggregated cross-border bank-to-bank flows, as doing otherwise could result in a misleading assessment of financial stability risks.

How bank credit-market funding helped spread the global crisis

Claudio Raddatz, 15 March 2010

How did a seemingly small shock to the US financial markets manage to spread so far, so quickly? This column argues that the heavy reliance on short-term wholesale funding is to blame. It follows that the discussions of regulatory reform should focus on the risks associated with the liability structure of banks.
