Yen Slumps After Intervention Amid BOJ Policy Decision Tensions

The Japanese yen came under renewed pressure on July 31 as markets tested Tokyo's resolve following a coordinated intervention to prop up the fragile currency. The dollar rose as much as 0.8% to 160.69 in early trades, after diving 2.4% in its biggest single-day drop since January 2023 in the previous session.

The yen-buying, dollar-selling market intervention conducted by Japan was a rare coordinated move that pulled the sagging currency from four-decade lows. Speculators have amassed large bearish bets on the yen, with weekly data from a U.S. regulator showing net short positions on the currency worth $11.65 billion, near the highest in two years.

The BOJ's policy decision is now under scrutiny as markets await an eagerly anticipated decision. Most analysts polled by Reuters expect the BOJ to raise rates again to 1.25% by year-end, citing the slow pace of rate hikes as a major factor behind the yen's decline. Nick Twidale, chief market strategist at ATFX Global in Sydney, believes that 'the market will push it back higher again and we've already seen signs of it this morning.'
