There is widespread agreement that government protection of banks contributed to the financial crisis, leading to proposals to require banks to finance a larger share of their portfolios with equity instead of debt – thus forcing shareholders to absorb losses instead of taxpayers. This column argues that equity ratios relative to asset risk are what matter, not equity ratios per se. Although higher equity requirements for banks may be desirable, the costs of reduced loan supply should be taken into account.
The resale-pricing aspect adopted by Apple’s agency model is highly controversial. Competition authorities fear that it raises retail prices. In the app market, resale pricing reduces prices to stimulate innovation and entrepreneurship. Prices of eBooks, though, increased when Apple entered the industry. This column analyses why this is the case.
Modern banks operate in a complex global financial ecosystem. This column argues that proper regulation requires an updating of our ideas about how they operate. Modern banks finance bond portfolios with uninsured money market instruments, and thus link cash portfolio managers and risk portfolio managers. Gone are the days when banks linked ultimate borrowers with ultimate savers via loans and deposits. The Flow of Funds should be updated to reflect the new realities.
What are the determinants of banks’ liquidity holdings and how are these reshaped by liquidity regulation? Based on a sample of 7,000 banks in 30 OECD countries, this column argues that banks’ liquidity buffers are determined by a combination of both bank- and country-specific variables. The presence of liquidity regulation substitutes for most of these determinants while complementing the role of size and institutions’ disclosure requirements. The complementary nature of disclosure and liquidity requirements provides a strong rationale for considering them jointly in the design of regulation.
Europe is set to finally approve new insurance regulation, Solvency II. This column argues that the final text should respect three fundamental principles to ensure solvency.
