The United States intervenes in the yen for the first time in 28 years—are your BTC positions ready for the "carry trade mass liquidation"?
Brothers, do you really understand what happened on Friday?
The U.S. Treasury stepped in. Through Goldman Sachs and Morgan Stanley, they sold euros and bought yen.
The last time the U.S. acted alone for the yen? 1998. 28 years ago.
The last U.S.-Japan joint intervention? 2011. 15 years ago.
This is not news. This is history. And historic-level moves never affect just one market.
Here’s what happened:
On July 31, the New York Fed, representing the U.S. Treasury, sold euros and bought yen through Goldman Sachs and Morgan Stanley. Earlier that same day, the Treasury had already notified several banks to "prepare for follow-up operations."
Even more outrageous—Treasury Secretary Janet Yellen, at the Camp David cabinet meeting, with reporters behind her, directly wrote in her notebook: "To-do: Buy yen, $5-10 billion."
Then it was photographed and spread worldwide.
Once the news broke, the USD/JPY dropped from 158.9 to around 157.6.
A Treasury Secretary’s notebook became the trigger for the global forex market.
But the real issue is here—
This is not just a forex story. It’s a signal of loosening in the world’s largest financing trade chain.
The yen’s annual interest rate is only 1%. In recent years, global traders have borrowed nearly zero-cost yen, converted it into dollars and euros, to buy U.S. Treasuries, U.S. stocks, and Bitcoin.
This is the yen carry trade—the hidden leverage source for global risk assets.
Now the U.S. personally intervenes to pull the yen, combined with the Bank of Japan’s $52.8 billion intervention on July 30, totaling nearly $60 billion in two days.
The yen surges—carry trades are forced to liquidate—those who borrowed yen to buy Bitcoin must sell coins to repay.
This is not speculation. The data is out.
Bitcoin fell below $63,000 after the intervention report, dropping 4.5% in the past 12 hours, wiping out $56.5 billion in market value. Ethereum dropped 4.6%, losing $10.3 billion. $240 million in positions were liquidated in the same period.
You’re not shorting. You’re just closing positions. The difference is—others are closing, you’re losing.
But isn’t a weaker dollar supposed to be good for BTC?
Textbooks do say that: weaker dollar, BTC rises.
But this time it’s different.
A weaker dollar benefits BTC in the long term. Carry trade liquidation crashing the market is the short-term reality.
When long-term logic and short-term reality collide—the short term always kills you first.
In May, Japan sold $66.75 billion in U.S. Treasuries to intervene in the yen, but the effect lasted only one month; by early June, the yen depreciated again.
This time? The U.S. personally stepped in. But the interest rate gap remains—the Fed’s rate hike expectations haven’t disappeared, and Japan’s rate is only 1%. $5-10 billion intervention in a forex market with daily trading volume in the trillions is just a drop in the bucket.
Can the U.S. and Japan’s coordinated action withstand the interest rate pressure? That’s the biggest question for next week.
My judgment:
First, short-term volatility is not over. Carry trade liquidation is a process, not instantaneous. $60 billion intervention crushed some yen shorts, but the interest rate gap remains, new shorts will come in.
Second, BTC’s "digital gold" narrative didn’t work this time. When risk aversion rose, BTC fell with risk assets. What does this mean? Facing liquidity contraction, BTC is still a risk asset, not a safe haven.
Third, watch two signals: Japanese Finance Minister Shunichi Suzuki will officially announce intervention on Monday—that’s expected. The real key is what the Fed does next. If rate hike expectations cool and the dollar continues to weaken, that’s the real long-term positive for BTC. But if it’s just intervention without solving the interest rate gap—the yen will return, and BTC will shake again.
The U.S. buying yen for the first time in 28 years—this event itself is more important than the result.
It tells the world one thing: the dollar system is loosening. The U.S. needs to pull the yen to support U.S. Treasuries because the yen depreciated too much → Japan sells U.S. Treasuries to intervene → U.S. Treasuries are sold off → Treasury yields rise → U.S. stocks and BTC collapse.
A chain reaction from Tokyo to Washington, from forex to bonds to crypto.
You think you’re trading crypto. Actually, you’re working for global macro liquidity.
