BofA Raises Yen Forecast, Expects USD/JPY to Reach 149 by End of 2026
Claire Weston
Bank of America raised its year-end yen target from 152 to 149, arguing that coordinated US-Japan intervention has fundamentally changed the market landscape; a September rate hike by the BOJ would give yen strength a fundamental anchor.
Why did BofA suddenly upgrade the yen target?
BofA lifted its year-end USD/JPY target from 152 to 149 — roughly 6% stronger than the current level near 158.
The trigger: a coordinated US-Japan yen-buying intervention, the first since 1998. Both governments said they would act jointly again if needed.
This means → the market is no longer watching Japan defend the yen alone. The US is on the same side, and the ceiling on intervention firepower has been raised dramatically.
Why has the "reserves will run out" thesis collapsed?
Bears had bet that Japan's finite FX reserves capped how long it could prop up the yen solo — eventually the ammunition runs out and the yen falls back.
BofA analysts wrote that with US participation, "the ultimate constraint on intervention has effectively been removed." In plain terms = Japan used to spend its own money buying yen, and the pot had a bottom. Now the US is spending alongside it — the ammunition depot has no lid.
This reflects a need to rewrite market pricing logic — the "safety cushion" for shorting the yen is gone.
How has the yen moved since the intervention?
The yen had weakened to near 164, a roughly four-decade low, driven mainly by a widening US-Japan rate gap.
Coordinated intervention pushed it back to about 155, sparking a four-session rally — though some of those gains have since faded.
This means → intervention worked in the short term, but staying power depends on fundamentals — specifically, whether the rate gap narrows.
Why is a September rate hike the key test?
BofA's report explicitly flagged the date: acting in September rather than waiting until October would let the BOJ show "its resolve to pre-empt upside inflation risks."
The Fed's target range currently sits at 3.5%–3.75%; the BOJ's policy rate is around 1%. That gap still powers the carry trade — borrowing cheap yen to buy higher-yielding dollar assets.
Put simply = without a narrower rate gap, intervention alone cannot hold. A September hike is the litmus test for whether this yen rally can stick.
What is BofA's longer-term yen call?
The analysts believe the coordinated stance points toward a shared goal: long-term yen stability, not a one-off rescue.
They see Japan as having "stronger reasons to deliver a broader policy response beyond FX intervention" — including a faster pace of rate hikes.
This reflects BofA's underlying logic: intervention is the signal flare; the real support comes from a monetary-policy pivot. The yen-strength story, in their view, is just getting started.
