Do financial regulations change bank behaviour? Does this create new risks? Under Basel II, some banks set capital requirements based on their internal risk models; others use an off-the-shelf standardised approach. These two methodologies can produce very different capital requirements for similar assets. See Figure 1, which displays a snapshot of recent risk weights for UK mortgages. In a new working paper we show empirically that this discrepancy causes lenders to adjust their interest rates and to specialise in which borrowers they target.

What are the consequences of proprietary trading? Banks typically hold and trade a significant amount of securities, and during the financial crisis, many of these securities suffered strong price declines. How did banks react? This is precisely what we investigate for the case of Germany in a recently published paper. We find that some banks increased their investments in securities, especially for those securities that suffered price drops. This strategy delivered high returns; but at the same time, these banks pulled back on lending to the real economy, since during the financial crisis they could not easily raise new (long-term) funding. Our findings suggest that proprietary trading during a crisis can lead to less lending to the real sector.
