Our baseline projection could change sharply depending on developments in the Middle East
In Tokyo, the Bank of Japan finds itself at the intersection of domestic ambition and global uncertainty — a central bank that spent a decade escaping deflation now must decide how quickly to tighten its grip on inflation while a distant conflict reshapes the very conditions it is trying to manage. Deputy Governor Ryozo Himino's careful words to parliament this week were less a policy announcement than a philosophical admission: that the pace of monetary healing depends not only on Japan's own recovery, but on the volatile rhythms of a world it cannot control. The BOJ presses forward, but with its eyes fixed far beyond its own borders.
- Rising Middle East tensions are driving energy prices higher, forcing Japan — a nation almost entirely dependent on imported oil — into a painful bind where the cure for inflation risks becoming a poison for growth.
- Markets have already made their bet: an 80% probability of a rate hike at the June 15-16 meeting, with three of nine board members having pushed for one in April, signals that internal pressure inside the BOJ is building fast.
- Japan's 10-year government bond yield hit 2.8% last week — its highest since 1996 — a tremor reflecting global anxiety that Middle East turmoil will accelerate inflation and force central banks into uncomfortable corners.
- Himino's repeated use of 'appropriate pace' is the BOJ's public signal that it will neither be stampeded by markets nor paralyzed by geopolitics — but the room for maneuver is narrowing with each barrel of oil.
The Bank of Japan is navigating one of its most complicated moments in decades. Deputy Governor Ryozo Himino told parliament this week that the central bank cannot simply follow its planned trajectory of rate increases — it must first reckon with what is happening in the Middle East, where conflict is reshaping the global energy landscape in ways that could fundamentally alter Japan's economic outlook.
The bind is structural. Japan imports nearly all of its oil, meaning that when Middle East tensions push energy prices higher, inflation rises — precisely what the BOJ is trying to contain. But those same rising costs drain household budgets and business margins, threatening the growth the BOJ is equally obligated to protect. Raising rates fights inflation but risks deepening the economic squeeze. Holding steady risks letting inflation run. Himino acknowledged the dilemma plainly: the BOJ's baseline projections, he said, could change sharply depending on how events unfold abroad.
Markets are not waiting for clarity. Traders now price in roughly an 80% chance of a rate hike at the June 15-16 meeting, and three of the BOJ's nine board members already voted for one in April. Japan's benchmark 10-year bond yield reached 2.8% last week — a level unseen since 1996 — reflecting broader global anxiety about fuel costs and inflation. The BOJ only ended its decade-long stimulus era in 2024, and the confidence that underpinned that exit is beginning to look more fragile.
Himino's message was one of deliberate steadiness: the BOJ will move, but at an 'appropriate pace' — a phrase he used twice, signaling that timing is as consequential as direction. What that pace ultimately looks like depends less on decisions made in Tokyo than on developments unfolding far beyond Japan's shores.
The Bank of Japan faces an unusually complicated moment. On Tuesday, Deputy Governor Ryozo Himino told parliament that the central bank cannot simply follow its planned path of raising interest rates. Instead, it must watch the Middle East conflict closely, because what happens there could fundamentally reshape Japan's economic outlook and force the BOJ to change course.
The tension is real. Japan's economy depends heavily on imported oil. When conflict in the Middle East drives energy prices higher, it pushes inflation up—exactly what the BOJ is trying to control. But those same rising energy costs also squeeze household and business spending, threatening economic growth. It is a trap: the medicine for inflation (rate hikes) could worsen the disease (slowing growth). Himino acknowledged this directly. "Our baseline projection could change sharply depending on developments in the Middle East," he said. The BOJ will continue raising rates, he insisted, but only at what he called an "appropriate pace"—a careful phrase that signals flexibility.
The market has already begun pricing in what it expects. After recent hawkish comments from other BOJ officials, traders are now betting there is roughly an 80 percent chance the central bank will raise rates at its next meeting on June 15 and 16. Three of the BOJ's nine board members already voted for a hike in April, signaling growing alarm about inflation. Himino himself voted to hold steady then, but his comments this week suggest the board is genuinely divided and watching events unfold.
The numbers tell part of the story. The benchmark 10-year Japanese government bond yield hit 2.8 percent last week—a level not seen since October 1996. That spike reflects global concern that Middle East turmoil will push fuel costs higher and accelerate inflation worldwide. Japan's own price forecasts have been sharply revised upward. The BOJ ended a decade of massive stimulus in 2024 and has already raised rates several times, including in December, based on confidence that Japan was finally achieving its long-sought 2 percent inflation target durably. That confidence now looks fragile.
Himino's message to the market was essentially: we understand the stakes, and we will move carefully. "It's important to maintain market confidence that inflation will be properly controlled," he said, "by adjusting the degree of monetary easing at an appropriate pace in line with economic, price and financial conditions going forward." The phrase "appropriate pace" appears twice in his remarks—a signal that speed matters as much as direction. The BOJ will not be rushed, but it will not hesitate either.
What comes next depends almost entirely on forces outside Tokyo. If Middle East tensions ease and energy prices stabilize, the BOJ can probably proceed with gradual rate increases as planned. If conflict escalates and oil prices spike, the central bank will face genuine pressure to either accelerate hikes to control inflation or pause them to protect growth. Himino's remarks amount to a public acknowledgment that the BOJ's next moves are no longer entirely its own to make.

The Hearth Conversation Another angle on the story
Why does the Middle East matter so much to Japan's central bank? It's thousands of miles away.
Japan imports nearly all its oil. When conflict there drives prices up, Japanese companies and households pay more for energy. That pushes inflation higher, which is what the BOJ is trying to control. But it also squeezes spending and growth.
So the BOJ is caught between two bad options.
Exactly. Raise rates to fight inflation, and you risk slowing an economy that's already fragile. Hold rates steady, and inflation could spiral. There's no clean answer.
The market is already betting on a rate hike in June. Does Himino's speech change that?
It signals the BOJ will move carefully, not automatically. The 80 percent probability reflects what traders think will happen if things stay roughly as they are now. But Himino is essentially saying: watch the Middle East. If things get worse, we might move faster or slower than you expect.
Three board members already voted for a hike in April. Is the BOJ fracturing?
Not fracturing, but genuinely divided. Some see inflation as the bigger threat. Others worry about growth. Himino's careful language suggests the board is trying to hold together while staying flexible enough to respond to whatever comes next.
