JPY Gains May Need More Than Rate Hikes

The Japanese Yen has already benefited from aggressive market pricing for a Bank of Japan (BoJ) tightening, but further gains may require additional policy tools beyond rate increases. According to OCBC FX Strategist Sim Moh Siong and Christopher Wong, the BoJ faces constraints on how far and fast it can raise rates.

The market is already pricing an 85% chance of a September hike, alongside a faster pace of tightening thereafter. The current pricing implies the policy rate rising from 1.00% to 1.75% by July 2027. This would break from the BoJ's pattern in the current tightening cycle, where rate increases have typically come about every six months.

Given these constraints, additional measures may still be needed to counter more persistent JPY depreciation pressures. One option could be policies aimed at encouraging the repatriation of overseas assets.
