BOJ Rate Hike Fails to Boost Dollar as Currency Markets Remain Volatile

The Bloomberg Dollar Index remained stable at 1,203.15 on September 18, 2026, following reports that the Bank of Japan (BOJ) was probing market participants on exchange rates.

The dollar-yen pair rose by 0.5% to 156.75, despite the BOJ's recent interest rate hike announcement that disappointed traders seeking clearer guidance on future borrowing costs.
