NEW YORK (Reuters) -The U.S. dollar on Wednesday hit its highest level against the Japanese yen in nearly 38 years, and investor speculation was high that authorities in Japan could intervene to strengthen the country’s currency, while major U.S. stock indexes climbed.
Japan’s top currency diplomat, Masato Kanda, said authorities were “seriously concerned and on high alert” about the yen’s rapid decline.
The U.S. dollar hit its strongest level since December 1986 against the yen, and it was last up 0.7% at 160.697 yen . The euro also surged against the yen, rising to 171.79, its highest level since September 1992. It was last up 0.3% at 171.625.
“The market seems to be front-running itself with respect to BOJ (Bank of Japan) policy,” said Eugene Epstein, head of structuring for North America at Moneycorp in New Jersey.
The yen has been hammered as investors flocked to dollar-based assets to take advantage of U.S. interest rates which are 5.25% to 5.5%. That is much higher than Japanese rates, which have been raised this year to a range of zero to 0.1%.
The dollar index, which measures the greenback against a basket of currencies, gained 0.38% to 106.07, with the euro down 0.34% at $1.0677.
