Banks may be unable to refinance short-term liabilities in case of solvency concerns. To manage this risk, banks can accumulate a buffer of liquid assets, or strengthen transparency to communicate solvency. While a liquidity buffer provides complete insurance against small shocks, transparency covers also large shocks but imperfectly. Due to leverage, an unregulated bank may choose insufficient liquidity buffers and transparency. The regulatory response is constained: while liquidity buffers can be imposed, transparency is not verifiable. Moreover, liquidity requirements can compromise banks' transparency choices, and increase refinancing risk. To be effective, liquidity requirements should be complemented by measures that increase bank incentives to adopt transparency.

There is much confusion about what shadow banking is. Some equate it with securitization, others with non-traditional bank activities, and yet others with non-bank lending. Regardless, most think of shadow banking as activities that can create systemic risk. This paper proposes to describe shadow banking as ?all financial activities, except traditional banking, which require a private or public backstop to operate?. Backstops can come in the form of franchise value of a bank or insurance company, or in the form of a government guarantee. The need for a backstop is in our view a crucial feature

This paper explores factors behind Canadian banks' relative resilience in the ongoing credit turmoil. We identify two main causes: a higher share of depository funding (vs. wholesale funding) in liabilities, and a number of regulatory and structural factors in the Canadian market that reduced banks' incentives to take excessive risks. The robust predictive power of the depository funding ratio is confirmed in a multivariate analysis of the performance of 72 largest commercial banks in OECD countries during the turmoil

We study the effects of a bank's engagement in trading. Traditional banking is relationship-based: not scalable, long-term oriented, with high implicit capital, and low risk (thanks to the law of large numbers). Trading is transactions-based: scalable, short-term, capital constrained, and with the ability to generate risk fromconcentrated positions. When a bank engages in trading, it can use its 'spare' capital to profitably expand the scale of trading. However there are two inefficiencies.A bank may allocate too much capital to trading ex-post, compromising the incentives to build relationships ex-ante. And a bank may use trading for risk-shifting.Financial development augments the scalability of trading, which initially benefits conglomeration, but beyond some point inefficiencies dominate. The deepening of financial markets in recent decades leads trading in banks to become increasingly risky, so that problems in managing and regulating trading in banks will persist for the foreseeable future. The analysis has implications for capital regulation, subsidiarization, and scope and scale restrictions in banking.
