The yen tumbled to the lower 144 range and hit a new 24-year low of 144.38 against the U.S. dollar on Wednesday in Tokyo, as the currency market responded to speculation that the Federal Reserve will not halt its interest rate hikes any time soon following upbeat U.S. economic data.

After topping the 143 line in New York overnight, the dollar continued to be bought in Tokyo as stronger-than-expected U.S. nonmanufacturing data from the Institute for Supply Management increased the likelihood that the Fed will continue with aggressive interest rate hikes, dealers said.

Further hikes would lead to widening U.S.-Japan interest rate differentials as the Bank of Japan sticks with its ultraloose monetary policy.

The yen continued to fall despite Japanese government officials signaling the country may intervene if the yen continues its rapid depreciation.

Tomoichiro Kubota, senior market analyst at Matsui Securities Co., said the market ignored the government's warning, saying it was "just talk" and "lacked details."

Kubota added that the market could "test the 147 level the Japanese currency hit in 1998."

The momentum of dollar-buying against other currencies may continue with the European Central Bank likely to increase interest rates on Thursday to tame rising inflation in the region, a move which would further weigh on the Eurozone's economy, dealers said.

"As investors remain deeply concerned about stagflation in Europe...they will continue to sell the euro against the dollar after (a possible) 0.75 percentage point rate hike by the ECB," pushing the dollar higher, said Yukio Ishizuki, a senior foreign exchange strategist at Daiwa Securities Co.

At 5 p.m., the dollar fetched 143.89-91 yen compared with 142.74-84 yen in New York and 141.53-55 yen in Tokyo at 5 p.m. Tuesday.The euro was quoted at $0.9923-9925 and 142.79-83 yen against $0.9902-9912 and 141.33-43 yen in New York and $0.9975-9976 and 141.18-22 yen in Tokyo late Tuesday afternoon.
