Japan’s yen is under pressure again — and this time, it’s coming straight from the top. Prime Minister Sanae Takaichi has nominated two dovish academics to the Bank of Japan’s policy board, spooking markets already on edge over her $135bn spending ambitions. The yen dropped 0.5% against the dollar to 1.55 on Wednesday morning. When your own central bank picks start looking like fiscal cheerleaders, investors tend to notice.
Who Did Takaichi Pick — and Why Does It Matter?
Takaichi tapped academics Ayano Sato and Toichiro Asada for two seats on the BOJ’s nine-member policy board. Both favour economic stimulus and lower interest rates — putting them at potential odds with BOJ Governor Kazuo Ueda, who’s been pushing to normalise policy and gradually raise rates.
The market read the room fast. If dovish voices gain influence on the board, Ueda’s rate-hiking path gets bumpier.

The Bigger Picture: Takaichi’s Spending Plans Are Rattling Markets
Takaichi swept to a landslide victory last month on promises to revitalise Japan’s economy. Her LDP won a lower house majority, and the yen briefly rallied on the news. That goodwill? Mostly gone.
Over the past two weeks, the currency has been sliding steadily as analysts digest the full scale of her fiscal programme.
What’s in the Spending Plan?
- A $135bn spending plan announced in November 2025
- A proposed two-year suspension of the 8% consumption tax on food — costing roughly ¥5 trillion per year
- Promises of higher defence spending and broader pro-growth policies
In her first major parliamentary speech, Takaichi pitched this as “responsible and proactive fiscal policy”. Markets aren’t buying it — particularly if spending pushes inflation above the BOJ’s 2% target.

What Analysts Are Saying
Ipek Ozkardeskaya summed up the mood bluntly: Takaichi’s apprehension over further BOJ rate hikes — combined with nominating reflationist academics — signals the yen will stay under pressure.
Not everyone agrees the nominations will reshape policy dramatically. Some analysts argue Ueda still holds significant sway over the board, limiting how much the new picks can steer decisions his way.
Stocks Up, Yen Down — The Split Reaction
Here’s the interesting twist: while the yen slumped, the Nikkei 225 jumped 2.2% to 58,583 points. Why? Cheaper money and more stimulus tend to be good news for equities, even when they’re bad news for the currency.
It’s the classic divergence — equity investors see fuel for growth, while FX traders see a debt spiral risk.
The Bottom Line
Takaichi’s BOJ nominations are more than a personnel decision — they’re a signal about who controls Japan’s economic direction. With the yen already weakening, debt concerns mounting, and a potentially compromised rate-hiking path ahead, markets are watching every move. The next few months will show whether her fiscal vision holds together — or starts to crack under the pressure.
FAQ
Q1: Why did the yen weaken after the BOJ nominations?
A: The nominees are known for favouring stimulus and lower rates, raising concerns they could slow the BOJ’s rate-hiking path. A slower pace of rate rises typically weakens a currency.
Q2: Who are the new BOJ nominees?
A: Academics Ayano Sato and Toichiro Asada — both described as “reflationist,” meaning they support policies aimed at boosting growth and inflation, even at the cost of a weaker yen.
Q3: How does Takaichi’s spending plan affect Japan’s debt outlook?
A: Her programme includes a costly food tax suspension and higher defence spending, raising fears she can’t fund it all without triggering a debt or currency crisis. Analysts remain sceptical of her fiscal maths.
Q4: What happened to Japanese stocks during the yen’s slide?
A: The Nikkei 225 rose 2.2% — markets priced in the prospect of more stimulus and looser monetary conditions, which tend to boost equity valuations.
Q5: Can Governor Ueda hold the line on rate rises?
A: Possibly. Many analysts say Ueda retains strong control over the BOJ board, meaning the new nominations may have limited practical impact on near-term rate decisions.
