BofA Securities warns that a sustained move in USD/JPY above 160 without intervention could weaken confidence in Japan's commitment to supporting the yen and send the currency toward 165. The pair was trading near 160 ahead of the July US consumer price index report, placing renewed attention on whether Japanese and US authorities would intervene to curb further yen weakness. BofA said a break above 160 followed by inaction would be interpreted as evidence of limited policy resolve, with USD/JPY potentially approaching 165 during August and the Japanese government bond yield curve likely to bear-steepen. Confidence in the authorities increased after Japan and the US conducted coordinated intervention on July 31, but that credibility has since eroded after officials declined to conduct follow-up intervention when weaker-than-expected US employment data pushed USD/JPY lower on August 7. A stronger policy response could restore confidence, while a more limited response would leave credibility diminished and repeated intervention to defend 160 could prove costly, potentially shifting the burden of supporting the yen from currency intervention to monetary policy.
BofA warns USD/JPY above 160 without intervention could bear-steepen JGB yield curve, implying higher yields.
