“This could shake things up across both forex and crypto,” said a currency trader closely watching the yen’s tumble. The US and Japan are gearing up for a rare joint move to stabilize the yen, a step not seen since 2011 when Bitcoin was still under $10. The yen has now hit its weakest point against the dollar since 1986, prompting swift action from both governments.
Japanese Finance Minister Satsuki Katayama has been coordinating with US officials, while the Bank of Japan quietly started buying yen during New York trading hours before any official word. Reports suggest the US Treasury may commit between $5 billion and $10 billion to this intervention, aiming to boost demand for yen by using dollar reserves. This preemptive buying signals the intervention is effectively underway, even before Monday’s expected formal confirmation.
The implications ripple far beyond traditional currency markets. The yen carry trade, where investors borrow yen at ultra-low Japanese interest rates to fund investments in higher-yielding assets, faces immediate pressure. When the yen strengthens suddenly, traders must repay more expensive yen loans, forcing them to offload assets including stocks and cryptocurrencies like Bitcoin and Ethereum. Similar dynamics were seen in 2024 after a Bank of Japan rate hike triggered a carry trade unwind, sending Bitcoin sharply down alongside global equities.
This move highlights how central bank policies and currency interventions can directly impact crypto markets. As the US and Japan prepare to act, traders will be watching closely for ripple effects on digital assets and risk-taking strategies. The scale and timing of this intervention could reshape market flows for weeks to come.
