Bettors on Polymarket now put 81% odds on a Bank of Japan rate hike in September. Two weeks ago, that same bet sat at just 22%.
The shift comes as Japan’s currency intervention loses its grip on the yen. The currency is on track for its biggest weekly loss in three months, unwinding much of its recent rebound.
Intervention’s Fading Boost
The yen fell about 1% this week to 159.43 per dollar. That puts it on track for its worst week since May.
The currency has given back roughly half the gains from Japan’s coordinated yen intervention in late July and early August. It was trading near 164 per dollar before that support began.
This is not the first time the boost has faded. Japan’s April intervention followed a similar path, and the yen drifted back toward 40-year lows over the following months.
Tokyo’s former top currency diplomat, Mitsuhiro Furusawa, told Reuters Japan could tap its yen war chest again at any time. He said officials could also signal faster rate hikes to defend the currency.
Bettors Pivot to a BOJ Hike
That link between intervention and rate hikes is why traders are shifting their bets. A quarter-point Bank of Japan hike is now priced at over 80% on Polymarket.
OCBC strategist Sim Moh Siong said intervention alone cannot shift the yen’s trend.
“It’s not much of a surprise that the yen has retraced.”
He said the currency needs a genuinely hawkish Bank of Japan behind it. That lines up with growing talk of faster BOJ rate hikes as inflation nears its target.
The bet carries risk. A hold instead of a hike could disappoint traders quickly. That kind of surprise has previously sent the yen sliding back toward 160. For now, markets are betting on the Bank of Japan, not further intervention, to hold the line.
