Dollar-yen lacked direction around 154.30 in Tokyo afternoon trading on Oct. 11, holding within a 154.21-154.61 range as profit-taking and position adjustments followed the prior day's advance. NYMEX WTI crude futures rose to the $103-per-barrel range and the US 10-year Treasury yield reached the 4.9% level as Middle East stabilization expectations faded, providing support for the dollar. Exporter dollar-selling orders between the upper 154 yen range and 155 yen capped gains. Euro-dollar remained soft in the low $1.16 range, while euro-yen traded higher with other yen crosses. Markets are watching Middle East developments and US economic data for their effect on oil prices, inflation expectations and Treasury yields.
