Bank of Japan Governor Kazuo Ueda, 74, was hospitalized on June 10, 2026 to treat an infected liver cyst, according to The Wall Street Journal and Kyodo News. He is expected to remain hospitalized for about two weeks, Yahoo News reported, which means he will miss the BoJ Policy Board meeting scheduled for the following week. A Deputy Governor will run the meeting in his absence, Nippon.com confirmed.

The timing matters because the BoJ has been in the middle of a major overhaul. Ueda has been steering the central bank away from decades of ultra-loose policy — ending a system called yield curve control, moving interest rates above zero for the first time since 2016, and figuring out how fast to raise rates further. Each policy meeting in this period sends strong signals to markets about what comes next. Having the Governor absent is not just a scheduling inconvenience; it removes the person who designed this entire plan from the room when his words are doing heavy work to shape expectations.

Who Chairs and Why It Matters

The Bank of Japan's Policy Board is a nine-member body that makes decisions as a group. The Governor chairs the meetings and, in practice, builds consensus before formal votes are taken. Having a Deputy Governor take over the chair keeps the institution running smoothly — votes still happen, minutes still get published, and any decision made is legally binding.

What changes is the signal the market reads. The Governor holds press conferences after the meeting, and those press conferences are how the BoJ talks to traders between official meetings. A press conference run by a Deputy Governor will be read differently by traders and strategists — not because the actual policy decision is different, but because the Deputy Governor's tone and views are a different input. Markets listen closely to who is speaking, not just what is said.

Which Deputy Governor chairs the meeting matters here. The BoJ has two: Ryozo Himino and Shinichi Uchida. Both have made comments this year that moved currency markets noticeably. Uchida in particular has a history of statements that markets have watched as hints of policy shifts ahead. Knowing which deputy will chair and answer questions at the press conference will itself be news.

What the BoJ Is Deciding

Ueda took over in April 2023 after more than a decade of the BoJ keeping rates near zero. His time as Governor has been defined by careful, though sometimes shocking to markets, steps forward: scrapping the yield curve control system, raising rates off zero, and navigating domestic wage pressures and global trade uncertainty.

Going into this June meeting, the core question is whether the BoJ hikes rates further, and if so, when. Wages have been rising; inflation in services (things like haircuts and restaurant meals, not goods) has stuck around longer than expected; and the outside world — especially U.S. tariff threats and slowing global growth — creates risks the bank has publicly warned about.

Before the hospitalization news, the main expectation was that the BoJ would hold rates steady and keep its options open with cautious language. Ueda's absence does not automatically change that plan — all board members vote, and Deputy Governors have the same vote weight as the Governor. But without Ueda in the chair, the meeting is more likely to end with a safe, consensus outcome rather than any signal that a rate hike is coming, simply because leadership uncertainty pushes toward avoiding surprises. This has happened before at other central banks during transitions: the actual policy does not shift, but traders re-price their guess about communication risk.

Health and Leadership Continuity

Ueda's term runs through April 2028. A two-week hospital stay for a treatable infection does not raise questions about whether he stays in the job. The BoJ has shown it values leadership continuity, and there is no rule that would force a change.

That said, Ueda is 74, and the work he is doing matters. Steering a central bank through a major shift in monetary policy — the kind the BoJ is executing — depends on one person telling a consistent story across meetings, speeches, and conversations with the government. Any sign that this continuity is at risk gets priced into markets, fairly or not.

Between now and the meeting, watch what the BoJ communications team does. Speeches Ueda would normally give will either be postponed or handled by deputies — each one a small signal that traders will piece together. The BoJ's quick, transparent announcement of the hospitalization and the two-week timeline shows it knows how much visibility matters. Gaps in leadership visibility can move both government bonds and currency markets.

What to Watch

The first and most important question: which deputy chairs the meeting and holds the press conference. That is the highest-value piece of information between now and the meeting date.

Beyond that, watch the overall tone of BoJ communication during the two weeks Ueda is out. Fewer than normal speeches or statements could itself signal that the bank is being cautious.

The yen carry trade — a bet that traders make, borrowing cheap yen to invest elsewhere — is already under pressure from the BoJ's overall shift toward higher rates. Clearer guidance usually helps; murkier guidance pushes traders to widen the range of rate scenarios they expect, and that widens the range can work against carry trades.

Ueda is expected to be healthy enough to return in about two weeks, which could mean he is back for statements after the meeting and for testimony to Japanese lawmakers. Whether and how he returns will be the next chapter.
