Bitcoin is having trouble making a convincing return to $80,000, and the latest obstacle is coming from an unlikely corner of global markets: Japan.
The cryptocurrency slipped as US stocks also weakened Wednesday, while fresh US-Iran strikes pushed oil prices higher and revived anxiety across risk assets. Bitcoin was down about 0.4% on the day as traders watched the yen strengthen against the dollar.
The move matters because the yen has become a key part of the market’s liquidity story. Japan’s currency was trading around 153 per dollar, its strongest level since February, while bets against the yen remained close to record levels.
At the same time, US Treasury Secretary Scott Bessent has signaled that further intervention in foreign exchange markets remains possible. Together, those developments are putting renewed attention on the so-called yen carry trade, a strategy that can amplify leverage across global markets when currency conditions shift quickly.
Bitcoin Is Feeling the Yen’s Pressure
Data from TradingView showed Bitcoin’s attempt to reclaim $80,000 losing steam. The move came as Wall Street opened lower, with the latest escalation involving US strikes on Iranian oil tankers adding pressure to already uneasy markets.
Oil prices responded immediately. WTI crude moved above $96 a barrel, while Brent climbed past $101 for the first time since late July. Higher energy prices can complicate the outlook for inflation and interest rates, giving investors another reason to reassess risk.
Bitcoin, meanwhile, remains sensitive to those broader macro moves. When liquidity expectations change, digital assets can quickly feel the impact, particularly when leveraged positioning is already elevated.
The yen adds another layer to the story.
Japan’s currency has gained about 6.5% since the beginning of August, trading near $0.0065. Earlier interventions by Japanese and US authorities helped accelerate the yen’s rise, while speculation has continued over whether Washington could restrict Japan’s ability to sell US Treasuries during future interventions.
Now, traders are facing a second problem: the amount of money still positioned against the yen.
Bloomberg data cited by Barchart showed that yen short positioning exceeded 5 trillion yen at the beginning of September, remaining near a record high. A stronger yen can put pressure on those positions, potentially forcing traders to unwind them as losses build.
That is where the carry trade enters the Bitcoin story.
Charu Chanana, chief investment strategist at Saxo, told Reuters that the yen’s continued strength could accelerate an unwinding of short positions. She pointed specifically to the USD/JPY pair as an important signal for liquidity conditions that can ultimately affect crypto markets.
“The carry trade is vulnerable because this unwind is happening before the BOJ has even delivered its expected hike,” Chanana said.
She added that while some yen shorts have already been reduced, positioning remains substantial enough that further yen appreciation could turn a controlled deleveraging process into something much faster.
The timing is particularly notable because the Bank of Japan is expected to deliver a 0.25% interest-rate increase at its next meeting on September 28.
Meanwhile, Bessent has made it clear that currency intervention is still on the table.
Last month, the Treasury secretary suggested Washington could support additional action in the yen market. On Tuesday, he returned to the subject at an event at Southern Methodist University in Texas, offering a pointed warning to traders betting against policymakers.
“When we intervene with the Japanese yen, I have pretty good insight into what the Bank of Japan is going to do, what Japanese policymakers are going to do. I have asymmetric information. I am the house now,” Bessent said, according to the Financial Times.
For Bitcoin, the problem is not simply that the yen is strengthening. It is that a stronger yen, heavy short positioning, potential central-bank intervention and higher oil prices are arriving at the same time.
That combination is making $80,000 a much harder level for Bitcoin to reclaim, while markets wait to see whether the yen’s latest move becomes a gradual adjustment or a more aggressive unwinding of global leverage.
