There is little empirical evidence that specialised banks are less stable or perform worse, as suggested by standard portfolio diversification theory. This column uses new data to argue that more specialised banks between 2002 and 2012 did not perform as theory would suggest. More specialised banks, and banks with similar sectoral exposures to their peers, suffered less volatility and had lower exposure to systemic risk. The lack of post-crisis regulatory reform in this area may, accidentally, have been a good thing.

Some economists are approaching a consensus that the Eurozone’s financial architecture is now resilient enough to withstand another shock similar to that of 2010-11. This column argues that such a view may be overly optimistic. Economic and financial instability persists in member states and the banking sector, and institutions to tackle a shock remain incomplete. While the Eurozone remains vulnerable to a bad shock, the blanket application of burden sharing without consideration of current economic and financial conditions is unwise.

In the years running up to the global crisis, the banking sector was marked by a high degree of leverage. Using US data, this column shows how, before the onset of the crisis, banks accumulated leverage both on and, especially, off their balance sheets. The latter activities saw an increase in maturity mismatch, raised the probability of bank runs, and increased both individual bank risk and systemic risk. These findings support the imposition of an explicit off-balance sheet leverage ratio in future regulatory frameworks.
