Bank of America Securities expects the Bank of Japan (BoJ) to raise its policy rate from 0.75% to 1.00% at the April 27–28 meeting. According to recent swap market pricing cited in BoJ minutes, traders are assigning roughly an 80% probability to that outcome.
A 25-basis-point move may appear modest. But in global macro terms, Japan returning to a 1% policy rate — a level last seen in the mid-1990s — carries symbolic and structural weight. The real debate is not about the number itself. It is about whether a shift toward policy normalization could accelerate the unwinding of yen-funded carry trades, tightening global liquidity and pressuring risk assets, including Bitcoin.
Why 1% in Japan Matters More Than It Sounds
Japan has anchored the global funding system for decades. Ultra-low rates and abundant liquidity made the yen one of the most popular funding currencies in the world. Investors could borrow cheaply in yen and deploy capital into higher-yielding assets abroad — U.S. Treasuries, emerging market debt, equities, tech stocks, and increasingly, crypto derivatives.
In August 2024, a sharp appreciation in the yen triggered by policy surprises and positioning stress led to rapid deleveraging. Bitcoin and Ethereum both dropped close to 20% within hours. The Bank for International Settlements (BIS) later described the episode as a classic forced deleveraging cascade: margin calls spread across futures, options, and cross-collateralized structures, with crypto acting as a liquid source of collateral.
The lesson was clear. Bitcoin may trade independently over long horizons, but during liquidity shocks it behaves like a high-beta risk asset.
1995 vs. Today: Similar Headline, Different Mechanics
On April 14, 1995, the BoJ set its discount rate at 1.00%. Days later, the U.S. dollar plunged to 79.75 yen, prompting coordinated central bank intervention. Within months, rates were cut again, ushering in decades of ultra-loose policy.
That period followed the 1994 “Great Bond Massacre,” when surging global yields erased an estimated $1.5 trillion in bond market value. Currency volatility, rate shocks, and policy uncertainty combined into a destabilizing mix.
However, today’s macro backdrop differs in key ways.
The Federal Reserve’s policy rate remains significantly higher than Japan’s. Even if the BoJ hikes to 1%, the interest rate differential with the U.S. would still be substantial. Structurally, the carry trade logic remains intact — at least on paper.
What changes is not the absolute rate level, but expectations about the future path. Markets move on trajectories, not single data points. If investors begin pricing a sustained tightening cycle in Japan, the yen could appreciate further, compressing carry profitability.
How Carry Trades Unwind — and Why Volatility Is the Trigger
Carry trade returns equal the interest differential minus currency appreciation in the funding currency.
For example, borrowing in yen at 0.75% to earn 3.5% in U.S. assets produces a 2.75% spread. But if the yen strengthens by 2.75%, that spread disappears. With leverage, small currency moves become amplified. At 10x leverage, a 1% move in the yen can translate into a 10% hit to equity — enough to trigger forced selling.
The real systemic risk is not the hike itself. It is a surprise combined with crowded positioning and thin liquidity.
In 2024, the BoJ’s hawkish tone exceeded expectations. The yen spiked. Volatility-control strategies reduced exposure. Derivatives positions were closed. Cross-currency basis spreads widened. Bitcoin, often used as liquid collateral within leveraged portfolios, fell alongside tech equities.
The key variable is volatility in USD/JPY, not simply the policy rate.
Capital Repatriation and U.S. Treasuries
Japan holds roughly $1.2 trillion in U.S. Treasuries, making it one of the largest foreign creditors of the United States.
If Japanese government bond (JGB) yields rise and the rate differential narrows, domestic institutions — pension funds, insurers, banks — may reassess foreign allocations. Holding U.S. Treasuries at 4% becomes less compelling when factoring in currency hedging costs, especially if JGB yields approach 1.5% without FX risk.
Repatriation does not occur overnight. But sustained flows back into Japan could place upward pressure on U.S. yields. Higher global yields raise the cost of capital and tighten financial conditions. Risk assets, including Bitcoin, often face headwinds in such environments.
The effect is indirect yet meaningful. Bitcoin’s valuation partly reflects global liquidity and opportunity cost dynamics. When risk-free returns rise, speculative demand tends to moderate.
Three Scenarios for April — and Bitcoin’s Response
Scenario 1: Hike with cautious guidance.
BoJ raises to 1% but emphasizes gradual normalization and data dependence. The yen appreciates modestly. Volatility remains contained. Bitcoin reaction limited or short-lived.
Scenario 2: Hike with hawkish forward guidance.
Stronger wage or inflation data reinforces expectations of further tightening. Yen rallies 3–5% in a short window. Volatility spikes. Risk-parity and volatility-targeting strategies de-risk. Margin calls spread. Bitcoin could face a 10–20% drawdown, similar to August 2024 conditions.
Scenario 3: No hike, dovish tone.
Rates remain at 0.75%. Yen weakens. Carry trades regain confidence. Liquidity conditions improve. Bitcoin and other risk assets benefit from renewed risk appetite.
What to Monitor Closely
– BoJ statement language and Outlook Report on April 27–28
– Forward guidance on inflation expectations and wage growth
– Implied volatility in USD/JPY
– CFTC positioning data for extreme short-yen exposure
– U.S. Treasury yield movements
– TIC data signaling capital flows
The phrase “Japan at 1%” can sound like a systemic warning. In reality, the outcome depends on communication, expectations, and liquidity conditions.
A well-telegraphed move may prove neutral. A surprise within a fragile liquidity environment could amplify deleveraging.
For Bitcoin, the distinction is critical. In gradual adjustments, it may revert to trading on its own supply-demand dynamics and institutional adoption trends. In abrupt tightening cycles, it can become part of the global liquidity shock transmission mechanism.
An 80% probability suggests much is already priced in. The remaining 20% — and the tone of the policy path beyond 1% — may determine whether this becomes a routine normalization step or a catalyst for volatility.
