A warning sign from Japan is flashing again. The USD/JPY exchange rate has climbed back above 160, a level that previously triggered a market crash last year. With the Bank of Japan meeting nearing, some traders fear another crypto sell-off.
Their concern comes from a similar event that previously led to a 25% drop in Bitcoin’s price.
The concern centers around the USD/JPY exchange rate, which has climbed back above 160.
For global investors, that level is more than just a currency milestone. It is widely viewed as a “line in the sand” for Japanese authorities. This level has become a major warning sign for markets because it previously triggered intervention from Japanese authorities.
In the past, Japanese authorities stepped in when the yen became this weak by selling dollars and buying yen. Japan recently spent a record ¥11.73 trillion ($73 billion) to support its currency, showing how seriously officials take a weak yen.
As the Bank of Japan approaches its June 15-16 policy meeting, markets are pricing in a roughly 97% probability of a 25-basis-point rate hike.
At the same time, officials are evaluating how and when to use their remaining intervention tools if pressure on the yen continues to build.
Meanwhile, a stronger yen isn’t just a problem for the dollar or US stock market; it is even threatening Bitcoin and the overall crypto market.
As borrowed yen become more expensive to repay, leveraged investors are often forced to reduce risk and close positions. That process can trigger selling across multiple markets at once.
Crypto traders, Crypto Rover point to the Bank of Japan’s March 2024 rate hike, Bitcoin fell roughly 23%. After the July 2024 hike, Bitcoin corrected between 25% and 30%.
The January 2025 hike was followed by a 31% decline, while the December 2025 move preceded another drop of more than 25%.
Those declines were not caused solely by Japan, but they highlight how sensitive Bitcoin can be when global liquidity conditions tighten.
The key question is whether Japanese policymakers will intervene again if the yen remains weak.
If authorities defend the currency and the Bank of Japan tightens policy further, pressure on the carry trade could intensify. That would reduce liquidity across global markets at a time when risk assets are already struggling.
As of now, Bitcoin price is already trading well below its April high, down by 15% since the beginning of this month, and currently trading around $62,900.
