Japanese Yen Strengthens on Rising JGB Yields and Expected Rate Hike

The Japanese Yen's value has been influenced by rising long-end Japanese government bond yields, according to OCBC strategists Sim Moh Siong and Christopher Wong. These yields are causing global curves to shift, making it more likely that the Bank of Japan (BoJ) will raise interest rates in September.

The BoJ's rate hike path is uncertain, but markets now price a high probability of a September rate increase, with implied odds rising to around 80% from 50% at the start of August. This increased likelihood has contributed to the JPY's strengthening against the US Dollar.

OCBC maintains its end-2026 USD/JPY target at 163, but may become more constructive on the JPY if the BoJ signals a more aggressive rate hiking path or if Japan encourages capital repatriation. Quarterly rate hikes through 2027 would be a key catalyst for a more durable JPY appreciation.
