Dollar-yen recovered in Tokyo trading on the 13th, reaching 159.48 yen after briefly slipping in early dealings, as the drop in WTI crude oil futures eased and a relatively firm 4.67% U.S. 10-year Treasury yield reinforced the market's yen-selling, dollar-buying bias linked to the Japan-U.S. rate gap. The pair stood at 159.43 yen at noon, about 0.01 yen firmer than the New York close of 159.42 yen, with the session range at 159.25 to 159.48 yen. Euro-dollar softened alongside the dollar's modest rise against the yen, trading at $1.1522 at noon versus $1.1526 in New York and touching $1.1520 at its low within a $1.1520 to $1.1531 range. Euro-yen moved sideways and struggled for direction between the firmer dollar-yen tone and weaker euro-dollar, standing at 183.69 yen at noon compared with 183.75 yen at the New York close, after ranging between 183.62 and 183.82 yen. Market participants said the pause in oil's decline reduced downward pressure on dollar-yen, but intervention caution tends to intensify as the pair approaches the upper-159 yen area, leaving trading confined to a narrow band without clear directional conviction.
