The market may revert to dip buying in USD/JPY as central bank risks loom and intervention odds remain high.

Fresh FX warnings pushed the pair toward its 159.37 Tenkan-sen, but large option-related gamma is limiting downside and helping anchor spot just below 160, supported by higher oil and Treasury yields.

While heavy short yen positioning, a flattening JGB curve, and softer technicals -- including a thinning daily cloud -- leave room for a pullback, a clear catalyst is lacking. Moreover, BOJ Governor Kazuo Ueda struck a cautious, mildly hawkish tone that offers limited support for sustained yen strength. While highlighting risks of inflation overshooting and falling behind the curve, he stressed the need to carefully weigh further tightening with policy still highly accommodative. This balanced stance echoes past messaging and aligns with government growth priorities, providing little conviction for a durable yen rally unless higher yields undercut risk sentiment. An extended move above 160 might invite MOF intervention, particularly if the yen weakens after an expected June BOJ hike. The options market is already pricing both that risk and a potential shift into a sustained 160+ range once expiries and key events pass. A close below 158 may be needed to arrest bullish sentiment.
