The Bank of Japan raises interest rates to 1%, hitting a 31-year high. How will yen carry trade unwinding impact the crypto market?

On June 16, 2026, the Bank of Japan decided at its monetary policy meeting to raise the policy interest rate by 25 basis points from 0.75% to 1.00%. This is Japan’s first return to the 1% interest rate era since 1995, after a gap of thirty-one years. The policy committee approved the decision with 7 votes in favor and 1 vote against. Because BOJ Governor Ueda Kazuo was hospitalized for treatment of a liver cyst infection, the meeting was chaired by Deputy Governor Shinichi Uchida.

For the crypto market, the real shockwave from the BOJ’s rate hike is not the interest-rate figure itself, but a covert yet massive transmission chain—yen carry trades—amplifying into the pricing system of global risk assets.

Rate Hike Takes Effect: Meets Expectations but Sends a Hawkish Signal

This rate hike is the BOJ’s first adjustment since December 2025, and a key step in its ongoing monetary policy normalization after it exited negative interest rate policy in March 2024. The market had already largely digested this expectation: a Reuters survey showed 66 out of 70 economists expected a hike to 1.0%, and Polymarket order-book odds also implied an approximately 98.3% probability of a 25 basis point increase.

However, “in line with expectations” does not mean “limited impact.” The BOJ also released a hawkish signal, indicating it will continue to raise policy rates depending on developments in economic activity, inflation, and financial conditions. Multiple institutions believe the rate-hike process will still continue, with the next hike possibly occurring by the end of 2026. This suggests Japan is accelerating its turn away from decades of ultra-loose monetary policy.

Yen Carry Trades: The Invisible Link Connecting Japanese Rates and the Crypto Market

To understand the impact of Japan’s rate hike on the crypto market, the key lies in understanding how yen carry trades operate.

Over the past several decades, the BOJ has kept interest rates at levels near zero or even negative for a long time. In this environment, global investors borrow yen at extremely low costs, convert it into U.S. dollars or other high-yield currencies, and then put it into higher-yield assets—U.S. Treasuries, global equities, emerging market bonds, and cryptocurrencies. The essence of this mechanism is using Japan’s role as a global “low-cost funding pool” to provide cheap leverage for risk assets worldwide.

The scale of yen carry trades is enormous. The Bank for International Settlements estimates that the size is roughly between $1.3 trillion and $1.7 trillion. Japan is the largest overseas buyer of U.S. Treasuries; over the past 14 months, it has had 13 months of continuous net purchases, with a total amount of $1.24 trillion—much of which is supported by low-cost yen financing. Cross-border arbitrage using yen as the funding leg extends risk budgets from foreign exchange and credit markets all the way into equity and crypto assets.

Closing Carry Trades: Why High-Beta Assets Get Hit First

When the BOJ raises rates, the cost of carry rises as well. Investors borrowing yen face higher financing costs and potential local-currency appreciation risk, forcing them to unwind positions—that is, selling the assets bought with yen financing and buying back yen to repay the loans. This process triggers a chain of sell-offs, and as a high-beta asset, cryptocurrencies are often the first to be hit.

As of June 9, leveraged funds held more than 115,000 yen short contracts, the highest level since November 2017. Such crowded short positions mean that if the yen strengthens due to the rate hike, coordinated short covering could amplify market volatility. For the crypto market, what truly needs attention is not only the rate hike itself, but also the potential chain reaction from hawkish policy language after yen short positions have already built up to elevated levels.

History has provided clear reference points. On July 31, 2024, an unexpected BOJ rate hike triggered a yen short squeeze, and Bitcoin fell from about $65,000 to $50,000 within a week. After the January 2025 hike to 0.50%, Bitcoin dropped 25% within 20 days; after the December 2025 hike to 0.75%, Bitcoin fell 3% following the announcement. Each tightening move by the BOJ leaves quantifiable traces in the crypto market.

Market Response After the Hike: Expectations Priced In and Structural Divergence

The market reaction after this rate hike shows characteristics different from past episodes.

Overall, the yen against the U.S. dollar moved only modestly, trading around 160.20. The Nikkei 225 index broke through the 70,000-point level for the first time in history during the session. After the decision was announced, Bitcoin rose from around $65,600 to near $66,000. As of June 16, according to Gate market data, Bitcoin was $66,184, up 1.0% over 24 hours; Ethereum was $1,788, up 3.9% over 24 hours.

This seemingly “bad news fully out” appearance actually confirms the logic that market expectations had been priced in sufficiently. JPMorgan noted that the current environment is clearly different from the summer of 2024—back then, the BOJ’s rate hikes and interventions were surprises, whereas this round had been partially priced in by the market. However, it bears watching that “in line with expectations” does not equal “risk is lifted.” The impact of closing carry trades on the crypto market is often lagged and structural—not a one-time sell-off triggered instantly by a single rate hike, but the slow removal of the yen carry premium embedded in asset pricing after low-cost leveraged funds gradually retreat.

Dovish Bond-Buying Plan: Liquidity Hedging Behind the Rate Hike

A detail that is easy to overlook but crucial in this decision is the BOJ’s dovish arrangement in its bond-buying policy.

The BOJ decided to keep unchanged its plan: from January to March 2027, it will reduce monthly Japanese government bond purchases by 1 trillion yen each quarter by quarter; then starting from April 2027, it will pause the reduction in bond purchases and maintain monthly purchases at about 2 trillion yen. This decision was approved with 7 votes in favor and 1 vote against.

This means that while raising rates, the BOJ deliberately slowed the pace of liquidity withdrawal. On one hand, it increases funding costs; on the other, it maintains liquidity supply in the bond market. To a certain extent, this policy combination of “rate hike + pausing balance sheet reduction” cushions the impact of tightening on financial markets. For Bitcoin, the BOJ’s unexpectedly dovish stance on bond purchases is one of the key factors supporting its steadiness after the hike.

The Global Central Bank Super Week: The Compounded Effect of Policy Divergence

This BOJ rate hike is not an isolated event; it is a key component of the “Global Central Bank Super Week.”

June 15 to 16 is when the BOJ holds its policy meeting, and June 17 is the Federal Reserve’s rate decision. With the two major central bank events arriving in less than 48 hours, and alongside the Reserve Bank of Australia’s policy developments, they form a three-part sequence of liquidity stress tests. If the BOJ hikes while the Federal Reserve keeps rates unchanged, the dollar may remain strong and the yen weak—potentially continuing to support carry trades in the short term. But if the Federal Reserve releases a hawkish signal, simultaneous tightening by both central banks could create an added effect of liquidity compression.

For the crypto market, the real risk is not just a policy adjustment by a single central bank, but the complex interplay between policy divergence among major central banks and synchronized tightening. The pressure from yen carry trade unwinds combined with elevated U.S. Treasury yields means the crypto market is facing a double squeeze on liquidity.

Summary

The BOJ’s decision to raise the policy rate to 1% marks Japan’s first return to this level since 1995, indicating that the world’s cheapest cost of financing is being systematically lifted. For the crypto market, this change is not a direct interest-rate shock transmitted straight through, but rather a gradual weakening of leverage support for high-beta assets via the implicit mechanism of yen carry trade unwinding. Historical data shows that every BOJ tightening has left volatility traces in the Bitcoin market. However, this time the reaction has been relatively mild in the short term because market expectations were fully priced in and because the dovish bond-buying plan provided hedging. Nevertheless, as the Global Central Bank Super Week plays out and carry trade costs continue to rise, the structural liquidity reshaping facing the crypto market is only just beginning.

FAQ

Q: What does the BOJ’s rate hike to 1% mean for the crypto market?

The rate hike itself does not directly determine the prices of crypto assets. But by increasing the cost of yen carry trades, it may trigger the selling of risk assets globally that were financed with yen. Cryptocurrencies are a high-beta asset, and in this transmission chain they sit at the sensitive endpoint.

Q: What is yen carry trade? How does it affect Bitcoin?

Yen carry trade refers to behavior in which investors borrow low-interest yen, exchange it into other currencies, and then invest in high-yield assets. A BOJ rate hike increases financing costs and forces investors to close positions—selling assets and buying back yen to repay loans—which can lead to risk-asset sell-offs, including Bitcoin.

Q: Why didn’t Bitcoin fall and instead rose after this rate hike?

This rate hike was widely expected (Polymarket implied a 98.3% probability), and therefore was priced in ahead of time. At the same time, the BOJ announced that it would pause the reduction in bond purchases starting from April 2027. This dovish arrangement hedged part of the tightening effect from the rate hike, leading the market to price the move under a “bad news already out” logic.

Q: What macro variables should crypto markets watch next?

Focus should be placed on the BOJ’s further rate guidance (with the market expecting a possible rise to 1.25% by year-end), the Fed’s June rate decision and its policy stance, and further changes in yen carry trade positions. The divergence of policy among major global central banks and the pace of synchronized tightening will be core variables affecting crypto market liquidity.
