Bitcoin Crashed 20%+ After Every Bank Of Japan Rate Hike?And Another One May Be Coming

Every Bank of Japan (BOJ) rate hike since 2024 has caused a Bitcoin (CRYPTO: BTC) crash of at least 20%.

With Japanese 10-year yields hitting a 27-year high if 2.32% on Monday, fears abound that another BOJ tightening cycle could trigger the next crypto selloff.

The Four Rate Hikes That Crushed Bitcoin

The BOJ raised rates four times since March 2024, and Bitcoin fell sharply after three of them. 

On March 19, 2024, the BOJ raised rates from -0.1% to a 0-0.1% range, ending eight years of negative rates. Bitcoin fell roughly 23% in the following weeks.

The July 31, 2024 hike to 0.25% triggered the most violent episode.

The yen appreciated from 160 to below 140 against the dollar, triggering a trillion-dollar global asset selloff.

Bitcoin crashed from $65,000 to $50,000, and the crypto market lost roughly $60 billion.

On January 24, 2025, the BOJ raised rates to 0.50%, and Bitcoin declined 25-31% over 20 days?the steepest percentage drop of the series driven by continued yen carry trade unwinds and forced liquidations.

The December 19, 2025 hike to 0.75% broke the pattern. Bitcoin bounced from $86,000 to $87,500 because speculators had already priced in the widely anticipated hike.

However, Bitcoin had already dropped from $125,000 in October to $86,000 by the meeting date.

The Yen Carry Trade Mechanism

For decades, investors borrowed yen at ultra-low rates to finance positions in higher-yielding assets like stocks and crypto. 

When the BOJ raises rates, borrowing yen becomes expensive, forcing traders to sell risk assets, buy yen, and repay loans?creating a cascade of forced liquidations.

Japan holds $1.1 trillion in U.S. Treasuries, making its policy shifts ripple across global bond yields, currency markets, and risk assets. 

Japanese life insurers hold $5 trillion in foreign assets. When long-end yields rise fast, they repatriate capital, selling U.S. Treasuries, European bonds, and emerging market positions funded by cheap yen.

The Warning Signs

The Japanese 10-year yield hit 2.32% Monday, up 13.1 basis points this month. 

The 30-year sits at 3.54%, up 15.4 basis points. The 40-year reached 3.77%, up 23.9 basis points?the largest monthly move on the curve.

BOJ board member Takata dissented for the second meeting, demanding a hike to 1%.

The yen is approaching 160 against the dollar. The Ministry of Finance warned it is “fully prepared to take action.”

Japanese securities dealers dumped a record 822 billion yen in super-long bonds in a single month earlier this year. The selling reflects balance-sheet survival, not discretionary trading.
