Bitcoin has developed a notably strong inverse relationship with the dollar-yen exchange rate over the past year.
BTC’s price has been closely tracking movements in the yen against the U.S. dollar, tending to fall as the Japanese currency weakens. This dynamic runs counter to the widely cited carry-trade theory, which argues that yen strength typically sparks risk aversion across markets, including crypto.
According to TradingView data, the 52-week rolling correlation between bitcoin’s USD price on Coinbase and the USD/JPY pair has dropped to -0.90, marking its most negative level since late 2022.
A correlation this deep signals a tight inverse link—bitcoin generally declines when USD/JPY rises (yen weakens) and gains when the yen strengthens. In effect, about 81% of BTC’s weekly price movements mirror shifts in the currency pair.
This trend calls into question the traditional carry-trade narrative, which associates a weaker yen with stronger performance in bitcoin and other risk assets. For years, traders have borrowed in low-yielding yen to fund positions in higher-return, riskier markets.
By that logic, a strengthening yen should lead to a pullback in risk assets. That pattern was evident in mid-2024, when the Bank of Japan raised rates, driving the yen higher and triggering a broad selloff. Bitcoin fell from around $65,000 to near $50,000 in the weeks that followed.
More recently, concerns about a potential carry-trade unwind have resurfaced as the yen slid to multi-decade lows, fueling expectations of possible intervention by the Bank of Japan.
However, if the current correlation holds, any policy-driven rebound in the yen could actually help stabilize or lift bitcoin prices—contradicting conventional expectations.
It’s also important to remember that correlation does not equal causation. The relationship does not necessarily imply that bitcoin and the yen are directly influencing one another.
A more plausible explanation is that broader moves in the U.S. dollar are impacting both assets independently, creating the appearance of a strong connection.
Markets are now pricing in at least one 25-basis-point rate hike from the Federal Reserve this year. This shift toward a more hawkish stance—reversing earlier expectations for rate cuts—has strengthened the dollar against major currencies such as the euro, Australian dollar, and New Zealand dollar, as well as against commodities like gold and silver.
Given this backdrop, traders should be cautious about relying solely on BTC/USD and USD/JPY correlations when forming market views.
