LONDON — The dollar staged a broad and powerful advance Monday to extend its historic rally as European central banks apparently refused to intervene against the currency's surge.
It was the 15th record-setting day for the dollar out of 17 business days this month, a performance that caused an astonished trader in Frankfurt, West Germany, to exclaim: "Every morning when we come in, the previous day's closing price looks cheap."
As the dollar resumed its climb, gold prices tumbled to a 5 1/2-year low. Republic National Bank in New York said gold bullion was bid at $283 an ounce, down $12 from Friday.
In its rise to new heights, the dollar set records against the currencies of Britain, Canada, France, Italy and Spain, rocketed to 13-year highs against the West German mark and the Dutch guilder and rose to a 10-year high against the Swiss franc.
The Federal Reserve Board said in Washington that its index of the dollar against 10 other currencies, weighted for international trade, shot up to a new high of 164.50 from the previous record of 162.09 on Friday. The index stood at 100 in March, 1973, and had slipped to 85.82 as the 1980s began.
Morgan Guaranty Trust Co. in New York said the dollar jumped to a record 40.9% above its average market value for the years 1980-82 as measured by its traded-weighted index against 15 other currencies.
"Fundamentally, the strong dollar reflects the bright performance of the U.S. economy compared to the lackluster behavior of other nations," Morgan Guaranty said in a quarterly economic report. "Foreign investors see that U.S. inflation is low, that innovative American companies offer attractive profit opportunities and that the political climate is reassuringly stable."
And the bank said that over the near term "foreign capital seems likely to continue flowing in at a rapid rate, helping to assure a strong dollar."
Traders said the markets were nervous, hectic and volatile.
One currency to recover some lost ground against the dollar was the Japanese yen.
The dollar rose to 263.05 yen in Tokyo from 262.35 yen on Friday. But by the end of the trading day in the United States, the dollar had slipped to 262.50 yen from 263.14 yen late Friday. There was unconfirmed speculation among traders that the Bank of Japan had sold dollars to support the yen.
