Introduction
“I sent my salary home and the amount my family received was less than before.” “I heard about forex intervention — does that mean the yen is getting stronger?” “Should I send money now or wait?”
Between late April and early May 2026, the Japanese government and the Bank of Japan carried out large-scale currency intervention. The yen, which had weakened past 160 to the dollar, briefly recovered to the 155 range — but as of May 20, it has drifted back to around 159.
This article explains what happened, what experts predict next, and how to think about timing your remittances home.
What You’ll Learn
- An estimated 10 trillion yen in forex intervention took place in April–May 2026
- The rate dropped from the 160s to the 155s, but has returned to around 159 by mid-May
- Experts are divided, but a major yen recovery within 2026 looks unlikely
- Splitting transfers over time is less risky than waiting for the “perfect” rate

What Happened: The April–May 2026 Forex Intervention
On April 30, 2026, the dollar-yen rate hit 160.72 — and then dropped sharply to the 155 range. Markets widely believe the Japanese government and Bank of Japan intervened by selling dollars and buying yen.
Additional intervention-like moves were observed on May 4 and May 6. The total estimated scale of intervention across these events is roughly 10 trillion yen.

For context, Japan spent roughly 9.2 trillion yen on intervention in 2022 and over 15 trillion in 2024. The 2026 intervention is on a similar scale.

Why the Yen Keeps Weakening
The main driver is the interest rate gap between Japan and the United States.
The U.S. federal funds rate remains at 4.75–5.00%, while the Bank of Japan’s policy rate sits at 0.50% after a modest rate hike in 2025. As long as this gap persists, investment money tends to flow toward the higher-yielding dollar, keeping pressure on the yen.
Forex intervention can temporarily push the yen stronger, but it doesn’t change the underlying rate differential. That’s why the yen tends to weaken again after each intervention.

Forex intervention means the government (Ministry of Finance) sells dollars and buys yen through the Bank of Japan. It temporarily boosts the yen’s value but doesn’t address the structural causes of yen weakness.
What’s Next: Expert Forecasts
| Institution | Forecast |
|---|---|
| Nomura Securities | Expects a moderate yen recovery to around 152–153 per dollar by the end of 2026 |
| NRI (Nomura Research Institute) | Views intervention as “buying time” — the structural weak-yen trend remains unchanged |
| MURC (Mitsubishi UFJ Research & Consulting) | Sees the rate likely staying in the 155–165 range through 2026 |

The common thread: a sharp yen recovery is unlikely. Unless the Japan-U.S. rate gap narrows significantly, expect the rate to hover in the upper 150s to lower 160s.
When to Send Money: Split Beats Wait
It’s tempting to wait for a better rate, but even experts can’t predict exchange rates reliably. The key is having a strategy that doesn’t depend on timing the market perfectly.
Practical advice:
- Split your transfers: Sending a fixed amount every month averages out the highs and lows. One bad timing call won’t hurt as much
- Set rate alerts: Apps like Wise and Revolut let you set alerts for specific rates (e.g., “notify me when it hits 155”). This way you can act quickly when the rate dips
- For large one-time transfers: If the rate drops back to the 155–156 range, that’s better than 159. But waiting too long for an even better rate often means missing the window entirely
Transfer fees matter as much as the exchange rate. Banks typically charge 4,000–7,000 yen per international transfer, while Wise charges around 600–800 yen for a 100,000 yen transfer. The fee difference can outweigh the exchange rate difference.

FAQ
Q. Will there be more forex intervention?
A. Additional intervention is possible if the yen weakens rapidly again. However, intervention tends to have only temporary effects and doesn’t reverse the underlying weak-yen trend.
Q. Should I send money home right now?
A. If you have a large transfer planned, waiting for a dip to the 155–156 range could save you money. But there’s no guarantee the rate will get there, so if the transfer is urgent, sending now at 159 is safer than waiting indefinitely.
Q. How can I reduce transfer fees?
A. Bank counter transfers tend to have the highest fees. Compare online services like Wise, Revolut, and PayPay to find the best option for your destination country and currency.
Q. Is a weak yen all bad for international residents?
A. It’s disadvantageous for sending money home, but it doesn’t affect your purchasing power within Japan. And if your family sends money to you in Japan, a weak yen actually works in their favor — they get more yen for less of their home currency.
Key Takeaways
- An estimated 10 trillion yen in forex intervention pushed rates from the 160s to the 155s, but the yen is back around 159
- The root cause of yen weakness is the Japan-U.S. interest rate gap — intervention alone can’t reverse the trend
- Rates will likely stay in the 155–165 range through 2026
- Splitting transfers over time is less risky than waiting for the perfect rate
- Compare transfer service fees — the difference between a bank and an online service can be several thousand yen per transfer
