USD/JPY Forecast: Yen shrugs off jawboning as pressure builds on BOJ

• BOJ holds rates at 0.75% with tightening bias intact
• Takata the lone dissenter, Tamura stays with majority
• JGB yields push higher on fiscal and energy concerns
• Katayama ramps up intervention rhetoric, but yen barely reacts
• USD/JPY clings to key support with downside risks building

BOJ holds with only one dissent

The Bank of Japan left rates unchanged in March, as expected, keeping its overnight rate at 0.75% with the decision passed by an 8–1 vote.

Hajime Takata dissented again, saying inflation is effectively at target and warning that rising import costs mean the Bank should already be running a higher rate.

But the bigger story may be who didn’t dissent. Back in November, both Hajime Takata and Naoki Tamura pushed for tighter policy ahead of the December hike. This time, Tamura stayed with the majority, leaving Takata on his own. For traders, that matters, it suggests the internal push for another near-term hike isn’t as strong as it was last time.

On the outlook, the Bank pointed to the Middle East and rising crude oil prices as a key risk. The message is pretty simple, if energy keeps climbing, it feeds straight into inflation in Japan, especially with a weaker yen still lifting import costs.

It also said inflation will likely dip below 2% in the near term due to government energy support, but that’s not the trend that matters. The Bank still expects underlying inflation to pick back up, helped by higher oil prices and wages continuing to firm.

Growth, in its words, is moderate. Nothing rolling over, but nothing running hot either. Consumers are still spending despite higher prices, businesses are investing, but housing is soft and global demand is patchy. Financial conditions remain easy, meaning it doesn't think policy is restrictive yet.

There wasn’t much said directly on the yen, but the signal was clear enough. The Bank said it will stay “vigilant” to financial and FX market moves and how they impact inflation. For traders, that’s the BOJ acknowledging that currency weakness and higher energy prices are part of the same story.

Importantly, the Bank didn’t shift its tightening signal. It still sees real rates, that is, nominal rates adjusted for inflation, as very low and said it will keep raising rates if the outlook holds. So the direction hasn’t changed, even if the urgency hasn’t picked up either.

A lot may now come down to the tone struck by Governor Kazuo Ueda later in the session, which should offer a clearer steer on how the broader Board is thinking about the rate outlook.

Market pricing reflects that.

A move in April is only slightly favoured at around 57%. Beyond that, markets don’t fully price the next hike until July, with roughly a three-in-four chance of another move by year-end based on swaps.

JGBs slide on fiscal risks

Even with the BOJ maintaining a tightening bias, pressure on Japanese government bonds hasn’t eased.

As flagged over the weekend, the JGB curve has been bear steepening, and that trend continued ahead of the decision, with yields rising across maturities, led by sharp moves in longer-dated tenors. Markets are still pushing for a higher rate path, even as the yen fails to respond.

The catalyst this time was another leg higher in energy prices. Crude and LNG futures rallied after attacks on energy infrastructure in the Gulf on Wednesday, first by Israel and then by Iran, adding to the pressure already building in Japan’s rates market.

For Japan, that’s a familiar problem. As a major energy importer, higher prices lift inflation expectations while also reinforcing concerns around energy security for an economy heavily reliant on external supply.

Put it together, and the same factors remain in play. Markets continue to test policymakers, leaning against both the bond market and the yen at the same time, even as the BOJ signals that further rate hikes are still on the table.

Yen reaction and intervention risk

USD/JPY had fallen earlier in the session following comments from Japan’s finance minister who said authorities were watching markets with an “extremely high level of vigilance”, were prepared to act at any time, and flagged that recent FX moves had been driven partly by speculation.

That combination from Katayama typically marks an escalation in rhetoric and is often seen just ahead of intervention, helping to lift the yen initially.

But the move didn’t last. Despite the stronger language, the yen has struggled to gain any real traction following both those remarks and the BOJ decision. That’s telling. Even with intervention-style language starting to creep in, the market isn’t biting.

After breaking beneath trend support dating back to the February lows earlier this week, USD/JPY has reclaimed the level despite the latest modest pullback, resting upon it ahead of Ueda’s presser. It remains the immediate focal point for traders, with 158.90 another support level just below, coinciding with the high set on March 9.

A clean break of those levels would open the path for a deeper flush, implying a trend change may be underway, bringing levels such as 157.88 and the intersection of the 50DMA and horizontal support at 156.53 into play. If sparked by intervention or a rate check from the MoF, a move through those levels would be likely.

On the topside, the pair remains capped beneath resistance at 160.23, a level that previously marked BOJ intervention in 2024. Less weight should be placed on them given the volatile market regime we find ourselves in, but the message from the oscillators points to gradually waning upside strength. Not a signal for bears to pile in, but an understandable shift given the threat of intervention.
