Bank of Japan hike odds triple on Polymarket as yen intervention fades
Polymarket traders have repriced the probability of a Bank of Japan rate hike to over 80%, up sharply from 22%, as Japan's yen intervention loses effectiveness in controlling the currency. The move reflects fading confidence that official intervention alone can stabilize the yen without accompanying monetary policy tightening.
Why this matters?
Shows Polymarket functioning as a real-time gauge of institutional sentiment on central bank policy, competing with traditional FX forwards and swaps for macro trade expression.
The bigger picture
Second time this month Polymarket macro odds have swung more than 60 points, after the Fed-hold repricing with Kalshi three days ago, testing whether prediction markets can hold a level as institutional hedging tools.
