O papel do governo na crise financeira

“How Government Created the Financial Crisis” de John Taylor (WSJ)

The classic explanation of financial crises is that they are caused by excesses — frequently monetary excesses — which lead to a boom and an inevitable bust. This crisis was no different: A housing boom followed by a bust led to defaults, the implosion of mortgages and mortgage-related securities at financial institutions, and resulting financial turmoil.

Monetary excesses were the main cause of the boom. The Fed held its target interest rate, especially in 2003-2005, well below known monetary guidelines that say what good policy should be based on historical experience. Keeping interest rates on the track that worked well in the past two decades, rather than keeping rates so low, would have prevented the boom and the bust. Researchers at the Organization for Economic Cooperation and Development have provided corroborating evidence from other countries: The greater the degree of monetary excess in a country, the larger was the housing boom.(…)

Other government actions were at play: The government-sponsored enterprises Fannie Mae and Freddie Mac were encouraged to expand and buy mortgage-backed securities, including those formed with the risky subprime mortgages.

Government action also helped prolong the crisis. Consider that the financial crisis became acute on Aug. 9 and 10, 2007, when money-market interest rates rose dramatically. Interest rate spreads, such as the difference between three-month and overnight interbank loans, jumped to unprecedented levels.

Diagnosing the reason for this sudden increase was essential for determining what type of policy response was appropriate. If liquidity was the problem, then providing more liquidity by making borrowing easier at the Federal Reserve discount window, or opening new windows or facilities, would be appropriate. But if counterparty risk was behind the sudden rise in money-market interest rates, then a direct focus on the quality and transparency of the bank’s balance sheets would be appropriate.

Early on, policy makers misdiagnosed the crisis as one of liquidity, and prescribed the wrong treatment.
