NEW YORK, AUG. 21 -- The dollar resumed its downward slide today after a one-day pause in a weeklong battering on foreign exchange markets, receiving no help from a favorable report on inflation and renewed central bank intervention.

Gold closed higher.

In New York, the dollar sank to 142.25 yen, down from Thursday's 144.85, and the lowest level since mid-June.

James Vick, senior corporate trader at Manufacturers Hanover Corp., said the Labor Department's report showing a modest 0.2 percent rise in the Consumer Price Index in July did nothing to stem the dollar's slide.

Vick said the CPI report, along with inflation-adjusted gross national product data showing a second-quarter growth rate revised downward to 2.3 percent from 2.6 percent, received "a knee-jerk reaction that was negative for the dollar.

"With the news out of the way, people felt more comfortable selling dollars than they would have in advance of the announcements," Vick said, adding that the numbers fell in line with expectations.

Overnight in Tokyo, the dollar dropped to 143 yen, down 0.75 yen from the previous 143.75, and the lowest rate in 70 days.

When the dollar fell to 142.60 in afternoon trading in Tokyo, the Bank of Japan intervened. The size of the central bank intervention today was estimated at between $50 million and $100 million, a dealer at Daiwa Bank Ltd. said.

Prime Minister Yasuhiro Nakasone indicated that intervention would continue.

"Exchange rates are to be self-determined by the market," Nakasone told the House of Representatives. "But we will take appropriate measures, as we have done in the past, against erratic rate fluctuations."

Despite Nakasone's comment, Vick said traders paid more attention to remarks made earlier in the day by Finance Minister Kiichi Miyazawa, who said there is a time when the market should be left alone to determine the dollar-yen levels.

Against the West German mark, the dollar ended at 1.8145 marks, down from its previous close of 1.8360. Earlier in Frankfurt, the dollar fell to 1.8283, down from 1.8363 on Thursday.

"We are just seeing the continued negative sentiment toward the dollar despite the rumored presence of the central banks," Vick said. "The turning point was a week ago with the trade number {a deficit of $15.7 billion in June}. That made the market focus once again on the fundamentals that people talked about even during the dollar's rise."

In London, the pound rose to $1.6295, up from $1.6190. Later in New York, the pound climbed to $1.6320, up from $1.6165
