As markets enter the holiday season, liquidity is thinning and volatility is rising and while most attention is on U.S. monetary policy and political developments, there’s another story quietly shaping global risk conditions: Japan. JPMorgan now expects the Bank of Japan to hike rates twice in 2025, potentially pushing policy rates toward 1.25% by the end of 2026. At first glance, these moves may seem modest, but for a market that has relied on decades of ultra-loose monetary policy, even incremental shifts have outsized consequences.

For years, the yen has been the preferred funding currency in carry trades, quietly fueling risk allocation across global equities, fixed income, emerging markets, and even crypto. Low-cost yen borrowing enabled leverage and amplified liquidity, effectively acting as a hidden tailwind for global risk assets. If the BOJ begins tightening, that tailwind begins to fade. Even small rate hikes reduce the attractiveness of borrowing yen to fund leveraged positions, and marginal liquidity becomes constrained. That can make even minor corrections cascade faster, especially in high-beta markets like crypto.
Bitcoin and the broader crypto market are particularly sensitive to these liquidity dynamics. While BTC has structural demand and increasingly behaves like a macro asset, many altcoins rely heavily on easy liquidity and leverage to sustain price levels. A tightening yen funding environment could lead to slower speculative flows, faster deleveraging, and sharper volatility. Even a partial unwind not a full-blown collapse can act as a catalyst for reassessing risk, reallocating capital, and differentiating between fundamentally strong projects and speculative excess.
Beyond liquidity mechanics, this development is a reminder that global risk conditions are fragmenting. It’s no longer enough to monitor U.S. rates, inflation, or Fed announcements; the interplay between currencies, funding costs, and cross-border capital flows now has a direct impact on how risk assets, including crypto, behave. A modest tightening in Japan can influence positioning in ways that ripple through both macro and crypto markets, highlighting the importance of staying alert and adaptable.
From my perspective, the BOJ’s gradual normalization adds another layer of complexity to 2025 not as an immediate shock, but as a slow drain on global risk tolerance. For crypto, that means fewer straight-line rallies, sharper volatility, and faster reactions to macro surprises. It also reinforces the point that liquidity tailwinds we’ve taken for granted for years can ebb quietly, creating conditions where discipline matters more than speculation.
My advice for crypto investors and traders in this environment: don’t panic, but adapt your positioning. Keep leverage in check, favor assets with structural demand and liquidity like Bitcoin, respect macro-driven volatility, and recognize that global funding conditions now matter as much as narratives or hype. When tailwinds like cheap yen funding fade, markets reward patience, selectivity, and disciplined risk management not reckless exposure. Focus on surviving first, then thriving, and let volatility work for you rather than against you.
In short, the BOJ’s expected tightening is a reminder that global liquidity regimes are shifting, and crypto markets, while resilient, are not immune. Understanding these dynamics and adjusting your approach accordingly is far more valuable than reacting to price swings alone. Markets are increasingly multi-layered, and the edge goes to those who see the connections before they materialize in price.
