Yen rallies as Ueda warns against delaying hikes; USD/JPY slides toward 155 ahead of heavy options
The Japanese yen surged on Tuesday after Bank of Japan Governor Kazuo Ueda signaled a greater willingness to raise rates if inflation risks build, knocking USD/JPY down about 0.7% toward the 155.00 handle and putting fresh two‑week lows in play.
Ueda turns up the hawkish dial
In a set of remarks that caught FX desks’ attention, Ueda cautioned that delaying rate hikes “for too long” could allow inflation to re‑accelerate, and reiterated that the BOJ would raise rates if the economy and prices evolve as forecast. He also underscored the risk that a weaker yen feeds FX‑driven inflation at a time when households are feeling the squeeze from higher prices.
The comments mark one of the clearest recent signals that policy normalization remains on the table, nudging traders to reassess the odds of a move at the BOJ’s 19 December meeting. While a hike had looked unlikely just days ago, today’s tone pushes the market toward a more balanced stance.
Market reaction: USD/JPY slips, volatility firms
USD/JPY fell to around 155.12 in afternoon trading, eyeing bids near the psychologically key 155.00 level. The pair has been capped below short‑term moving averages since last week, and today’s move accelerates that downside momentum. Intraday vols ticked higher as spot approached a cluster of large option expiries around 155.00 due Wednesday, a potential magnet for price action into the New York cut.
Broader risk sentiment remained cautious, with traders weighing the interplay between BOJ normalization risk, FX‑pass‑through to inflation, and year‑end liquidity conditions. For carry trades funded in yen, even a subtle repricing of BOJ risk can force position trimming and add to yen strength.
Technical picture: 155.00 in focus
Below 155.00, momentum accounts will eye follow‑through into recent lows, while failure to clear the figure could invite a bounce toward near‑term moving averages overhead. With spot already in a lower intraday channel, the burden of proof sits with dollar‑yen buyers to reclaim lost momentum.

Key Points
- Yen strengthens; USD/JPY down about 0.7% toward 155.00, near two‑week lows
- BOJ’s Ueda warns against delaying hikes and flags FX‑driven inflation risks
- Traders reassess odds of a December BOJ move ahead of the 19 Dec. decision
- Heavy USD/JPY option expiries around 155.00 could steer near‑term price action

Analyst view
Today’s hawkish emphasis tightens the BOJ’s narrative around inflation control and FX pass‑through. Even without an imminent hike, guidance that keeps normalization live can lift yen term premia and curb dollar‑yen upside, particularly as year‑end liquidity amplifies option‑related flows. For now, the path of least resistance points to choppy trading around 155.00 with headline risk elevated. This article was prepared by BPayNews.
FAQ
Why is the Japanese yen stronger today?
The yen rallied after BOJ Governor Ueda warned that delaying rate hikes could let inflation re‑accelerate and highlighted FX‑driven price risks. Markets interpreted the remarks as a more hawkish stance, prompting a reassessment of BOJ hike odds and pushing USD/JPY lower.
What did Ueda say that moved markets?
He said the BOJ would raise rates if prices and the economy move as forecast, cautioned against waiting too long to tighten, and flagged that yen weakness can fuel inflation that’s already pressuring households.
What are the key USD/JPY levels now?
The 155.00 handle is the near‑term pivot, with large option expiries clustered there. Below it, momentum could extend toward recent lows; above it, resistance sits near short‑term moving averages on intraday charts.
Could the BOJ hike in December?
It’s not a done deal, but today’s messaging increases the probability relative to last week. Traders will watch upcoming data and BOJ commentary closely heading into the 19 December meeting.
How do option expiries impact USD/JPY?
Large expiries can attract spot toward strike levels as dealers hedge gamma exposures, often damping directional moves near the strike before the cut and then releasing volatility afterward if positioning clears.
