#加密市场观察 How will Japan's interest rate hike affect the crypto market, and could there be a black swan?

The likelihood of the Bank of Japan raising interest rates on December 19, 2025, is very high. The market generally expects a 25 basis point hike to 0.75%, with an over 80% probability. A former BOJ official predicts that there could be three more rate hikes after this, with the final rate reaching 1.5%.

The upcoming rate hike by the Bank of Japan (BOJ) centers around withdrawing the "cheap yen" that has supported global high-risk assets for decades, which will trigger a severe market reassessment.

To understand its power, first recognize a hidden giant — yen arbitrage trading. Over the past few decades, Japan’s near-zero interest rates made the yen the cheapest financing currency worldwide. Investors borrow almost free yen, convert it to dollars, and flood into high-yield assets like U.S. stocks, emerging markets, and cryptocurrencies. This model is massive, with some analysts estimating its total exceeding $19 trillion.

Core Impact Pathways: Reversal of Cheap Capital Flows

Once the BOJ continues to hike rates, this enormous capital chain will begin to tighten in reverse, exerting multiple pressures on the crypto market:

1. Direct Impact: Arbitrage Liquidation

· Cost Surge: Borrowing costs for yen are no longer free, squeezing arbitrage margins.
· Exchange Rate Pressure: Rate hike expectations drive the yen’s appreciation, leading investors to face exchange losses when repaying yen loans.
· Forced Liquidation: Facing dual pressures, institutions holding large leveraged positions will prioritize selling the most liquid assets to repay loans, often targeting crypto assets first. Some analyses point out that Bitcoin, which dropped from around $92,000 to $83,800 in early December 2025, was directly related to arbitrage liquidations triggered by yen strengthening.

2. Indirect Impact: Tightening Global Liquidity and Reduced Risk Appetite

· Liquidity Source Tightening: The world loses an important low-cost funding source.
· Shift in Capital Attraction: If Japanese government bond yields continue rising to attractive levels (the 10-year yield recently hit highs not seen since 2008), capital may flow back to Japan from overseas, further draining risk markets.
· Risk Aversion Rise: Against the backdrop of “Japan tightening, the U.S. possibly easing,” global market uncertainty increases, and risk-averse sentiment will first impact high-volatility assets like Bitcoin.

Could this be a “Black Swan”?

Likely not a complete “black swan,” but tail risks cannot be ignored.

· Market Expectations: Currently, the market highly anticipates the BOJ’s rate hike at the December 18-19 meeting, with probabilities once rising to 70%-80%. The real “black swan” would be an unforeseen sudden shock, but markets are already gradually digesting this.
· Partial Digesting: The Japanese bond yield curve has risen significantly this year, reflecting market pricing in the policy shift.
· True Risk Points: The real risk lies in the rate hike exceeding expectations in magnitude or pace, or during the liquidity-scarce period at year-end (such as December 19), triggering chain reactions of margin calls and leverage unwinding.

Market Reaction Forecast: Short-term Pain and Long-term Divergence

Based on various analyses, market responses may occur in three stages:

Short-term (a few days before and after the decision): Volatility and downward pressure.
This is the period of greatest market tension. Any hawkish surprise signals will quickly trigger sell-offs through arbitrage liquidations. Investors should be especially cautious of extreme volatility risks in highly leveraged altcoins.

Mid-term (weeks to months): Market will seek new equilibrium.
After panic selling subsides, markets will re-price based on the new liquidity environment and policy outlook. Notably, some analysts suggest that the policy uncertainty being resolved (“the shoe dropping”) could eliminate a major uncertainty, and historically, Bitcoin tends to show resilience after macro pressures. Meanwhile, yen appreciation will also reduce the cost for Japanese domestic investors to hold dollar-denominated crypto assets.

Long-term (structural impact): Reshaping the global crypto capital landscape.
If Japan enters a sustained rate hike cycle, it will have profound effects on global capital flows. This could force the crypto market to reduce reliance on a single cheap currency leverage. Additionally, Japan’s clear regulatory framework and potential exploration of digital yen (CBDC) may attract new compliant institutional funds.

Countermeasures:

In summary, Japan’s rate hikes will have systemic impacts on the crypto space, tightening global liquidity “valve” and testing the market’s leverage and risk appetite.

For investors, rather than guessing the outcome of a single event, it’s better to examine your own holdings:

· Reduce leverage: This is the primary step to cope with any macro shocks.
· Focus on core assets: During market turmoil, mainstream assets with high liquidity (like BTC and ETH) have much stronger risk resistance than altcoins.
· Monitor key signals: Keep close tabs on USD/JPY exchange rate and Japanese bond yields, as they are leading indicators of capital flows.

Every major market stress test exposes risks and serves as a test of long-term value and narrative strength. This time is no exception.#广场发帖领$50 #参与创作者认证计划月领$10,000
