Bank rates soar on cash dash

LONDON/NEW YORK (Reuters) - The cost of borrowing overnight dollars skyrocketed on Tuesday, prompting central banks worldwide to unleash billions into money markets to prevent them from a lockup, a day after U.S. lawmakers' rejection of a $700 billion (388 billion pound) financial industry bailout.

A flood of money from central banks seemed successful in meeting banks' quarter-end scramble for cash. It helped to drive the overnight lending rate between U.S. banks close to zero percent from its multi-year high.

"Money markets are more of a problem than stock markets. Perceived counterparty credit risk ... probably won't go away for a while," said Everett Brown, strategist at IDEAGlobal.

The hoarding of cash was especially aggressive in the euro zone, where a handful of banks have been rescued by governments since Monday due to rising losses stemming from the credit crisis.

Cash was also in demand among investors to settle trades whose values swung wildly over the past several months.

The London interbank offered rate (Libor) for overnight dollars jumped by a record 430 basis points to 6.87 percent, the highest in at least 7-1/2 years.

QUARTER-END HUMP

Reflecting the scarcity of funds in the interbank market, banks also borrowed 15.481 billion euros overnight from the ECB, the largest amount in almost six years.
