NEW YORK, AUG. 22 -- The stock market took another drubbing today, faced with relentless pressure from worries over soaring oil prices and rising interest rates.

The Dow Jones industrial average fell 43.81 points to 2560.15, extending its loss since July 17 to 439.60 points, or 14.65 percent of its value.

The last time the average recorded a lower close was on Jan. 30, when it hit its 1990 low of 2543.24.

Declining issues outnumbered advances by more than 3 to 1 in nationwide trading of New York Stock Exchange-listed stocks.

In morning trading Thursday in Japan, the key index on the Tokyo Stock Exchange fell nearly 1,000 points in light trading as investors grew more fearful of rising oil prices, traders said. The 225-issue Nikkei stock average lost 949.96 points, or 3.77 percent, ending the morning session at 24,206.95. The index shed 1,086.93 points Wednesday, its ninth-largest daily drop.

On the New York bond market, inflation fears kept dragging prices lower. Yields on long-term government bonds topped 9 percent for the first time since early May.

Stocks have attracted a few sporadic buyers in recent days, apparently spurred by hopes that the market has gone to extremes in its appraisal of the potential ripple effects of Iraq's invasion of Kuwait. But a good many analysts questioned whether the market has fully adjusted to the increased recession risks arising from the situation in the Middle East.

Stock markets in other financial centers around the world remain on the defensive amid fears of increased inflationary pressures and higher interest rates.
