BOE slashes key interest rate by 1.5%, ECB by 0.5%

Two major central banks took drastic monetary policy action Thursday to further stimulate their economies. The Bank of England unexpectedly cut it benchmark interest rate by a gargantuan 150 basis points to 3%. Meanwhile, the European Central Bank cuts its key rate, the refinance rate, by 50 basis points to 3.25%.

"There has been a very marked deterioration in the outlook for economic activity at home and abroad," the Bank of England said in a statement.

Economist Richard Felson had expected a 75-basis-point cut by the BOE. "We know that several business surveys in the U.K. are pointing to a pronounced contraction, with consumer spending showing little life. I think those facts, and the tighter credit markets, prompted the decision," Felson said. "Few expected as large a cut, but it was the correct move, and there's likely to be additional rate cuts ahead."

The BOE has now cut interest rates by 200 basis points since October 8.

The ECB also took bold action to stimulate growth, with a 50-basis point cut. Felson said continental Europe is likely to experience the effects of the downturns in consumer and business demand later, but the fact that the hawkish-leaning ECB "is in full accommodation mode" is a sign of the scope of the economic slowdown.
