Yen’s Sudden Reversal: Real Intervention or Just Market Fear?
Last Friday, something surprising happened in the currency market.
The Japanese yen suddenly became very strong and jumped more than 3.5 yen against the US dollar in a short time. This move shocked traders and created a lot of noise in the market.
Everyone started asking the same question:
👉 Did the Bank of Japan secretly intervene again?
No Clear Proof of Intervention (For Now)
On Monday, official data was released — and it told a different story.
Japan’s current account balance is expected to decrease by 630 billion yen.
Yes, this number is bigger than expected, but when we compare it to past interventions (which were over 1 trillion yen), this amount looks very small.
Many analysts were not convinced at all:
Yuichiro Takai (Tokyo Tanshi) said the amount is too small to confirm intervention.
Tsuyoshi Ueno (NLI Research) was even more direct, saying that fluctuations of a few hundred billion yen are very common, and the government probably did nothing.
So if Japan didn’t step in…
👉 Why did the yen suddenly jump so hard?
The Real Trigger: US “Currency Check” Rumors
Here’s where things get interesting.
During the New York trading session, reports came out that US officials were doing a “currency check.”
As soon as traders heard this, the market reacted fast.
Why? Because this raised the idea of a possible US–Japan joint intervention.
📌 Important reminder:
The last time the US and Japan worked together to support the yen was back in 2011.
Why Joint Intervention Matters So Much
If the US is really supporting Japan, the message is very strong:
💬 “Stop betting against the yen.”
For yen short sellers, this would be a serious warning.
Even the possibility of joint action is enough to scare the market — and that fear alone can move prices.
Japanese Officials Keep It Mysterious
Japan’s Finance Minister Shunichi Suzuki refused to give clear answers and avoided confirming anything. This only increased uncertainty.
Meanwhile, Chief Cabinet Secretary Hirokazu Matsuno said:
“Japan and the US are in close communication and will act based on agreements.”
This statement didn’t confirm intervention — but it didn’t deny it either.
Psychological War in the Market
Right now, the market feels like a mind game.
BOJ Governor Ueda keeps saying interest rates will rise, but actions remain slow.
The yen keeps moving wildly.
Traders are nervous, wondering:
👉 “Who dares to intervene first?”
Some believe Japan hasn’t intervened since July, when USD/JPY hit 161.95.
If Japan really steps in again, it could force earlier interest rate hikes, which would be a big shift.
Final Thoughts
Until January 30, when official data is released, everything remains unclear.
But one thing is certain:
🔥 Traders are on edge.
Many fear that atof any moment, the so-called “national team” could jump in and crush aggressive yen shorts.
For now, the yen story is not over —
and the next move could surprise everyone.
