Take away some of the incentives for consumer lending
Anyone who lives in the US and receives ten pre-approved credit card offers each week and still, six months into a crisis, has to answer five phone calls a day offering mortgages, must know that some other forces than asset prices must be driving debt creation.
Since so many seem capable to so easily switch from praising the US for being the locomotive of world growth to “being the main culprit behind the destabilizing global imbalances” let me at least point out what I think is also responsible for the current sad state of affairs.
The securitization of consumer debt which allowed the creation of low risk financial instruments, plus the introduction of the minimum capital requirements for the banks and which are exclusively based on risks, as perceived by the credit rating agencies, constituted a massive dose of incentives for the financial system to go after the consumers, in the US and everywhere. Taking away some of the incentives to offer unreasonable consumer credits might long term be a much wiser thing to do for a nation than having the price of their assets fall from the skies.
