OCBC’s Sim Moh Siong and Christopher Wong highlight that Japan’s recent FX intervention, backed by United States (US) involvement, has not fully reversed Japanese Yen (JPY) weakness, with USD/JPY near 159 after retracing much of its post-intervention drop. They keep an end‑2026 USD/JPY forecast at 163 but say a more aggressive Bank of Japan (BoJ) hiking path and domestic capital flows back into Japanese assets could drive a more sustained JPY recovery.
"Questions remain over whether Japan’s intervention, likely larger in scale and stronger in signalling power given US involvement, can reverse the JPY’s underlying weakness."
"With USD/JPY approaching 159, the pair has already retraced almost 40% of its decline from the pre-intervention high of 164 to the post-intervention low near 155.50. We suspect both Japan and the US stand ready to intervene again if needed to stabilise the JPY."
"We maintain our end-2026 USD/JPY forecast of 163. However, we could turn more constructive on the JPY if the BoJ follows through with a more aggressive rate hike path and if policies that encourage GPIF and NISA-related flows back into Japanese assets materialise."
"Coordinated intervention has also fuelled expectations of earlier or faster BoJ tightening, helping to stabilise long-end JGB yields. The key risk is that a more stable JPY reduces the urgency for the BoJ to raise rates. With markets pricing around a 60% probability of a September hike, upward pressure on both USD/JPY and long-end JGB yields could re-emerge if the BoJ keeps rates unchanged."
"Conversely, a September rate hike, combined with evidence of domestic investors reallocating capital back into Japanese assets, could drive a more sustained JPY recovery and provide longer-lasting relief for long-end JGB yields."
