USD/JPY Holds Near 159.80 as BoJ Eyes 160 Intervention Line

USD/JPY steadied near 159.80 on 4 June after probing the 160.00 threshold, with markets now bracing for possible Bank of Japan intervention amid renewed dollar strength. The pair had traded quietly around 159.20-159.30 on 29 May before edging higher to 159.45 on 1 June and 159.70 on 2 June. Sharp swings on 3 June took the rate from 159.37 to 159.95 as Gulf tensions lifted WTI crude to $95.70 and the US 10-year yield to 4.48%, keeping yen volatility elevated. Asian currencies steadied on 4 June after recent losses, but the dollar remains supported by robust US data and geopolitical risk.
