Competition among banks is healthy for all, except when banks are allowed to compete on stratospheric capital leveraged heights.

Sir, Nicholas Megaw reports on some natural concerns derived from the fact that “Britain’s banks and building societies are loosening lending standards and cutting fees to maintain growth, as competition and a weakening housing market squeeze profit margins.” “UK banks loosen mortgage standards to maintain growth” August 26.

Competition among banks is always good, what were we borrowers to do without it? If as a result, some banks fail, so be it, and in fact that is quite necessary for the long-term health of the system. 

But when competition occurs where regulators allows too much leverage, because they also perceive it as very safe, then the very high exposures to the same class of assets, by many banks, can really explode and endanger the bank system.

So in conclusion, welcome the lowering of lending standards for loans to entrepreneurs that bank competition can bring about; but the capital requirements for banks when financing residential mortgages need to be increased, in order to make competition less dangerous. 

PS. Here is the somewhat extensive aide memoire on some of the mistakes in the risk weighted capital requirements for banks.
