Bitcoin remained stable over the last 24 hours, trading at approximately $63,600, even as the United States and Japan took coordinated action to bolster the yen. This rare intervention has reignited worries regarding the inexpensive Japanese funding that underpins leveraged investments across global markets.

On Friday, both nations confirmed their purchases of yen following a decline that saw the currency drop to 163.73 per dollar. According to data from the Bank of Japan, it's estimated that Tokyo may have expended around $36.6 billion, although the exact amount contributed by the U.S. remains undisclosed.

The yen bounced back to 157.57 on Friday and maintained a level close to 157 on Monday.

Cryptocurrency traders pay close attention to fluctuations in the yen due to its connection to the carry trade strategy. Investors typically borrow in Japan, where interest rates stand at 1%, and then invest those funds into assets that yield higher returns.

A swift increase in the yen's value could compel these traders to liquidate positions and sell off other investments in order to settle their loans.

However, this risk did not immediately impact Bitcoin's performance. On Monday, BTC was up roughly 1.8% over the past day and showed little movement over the week.

Alvin Kan, COO of Bitget Wallet, noted that the intervention should be interpreted more as a measure to stabilize chaotic trading rather than a sign of a sustained recovery for the yen.

The disparity in interest rates continues to favor the dollar, with the Federal Reserve’s target range set at 3.50% to 3.75%, compared to the Bank of Japan’s 1%. Unless this gap narrows or investors begin to unwind yen-funded trades voluntarily, ongoing interventions may merely delay the yen's depreciation.
