While much of the 2025 crypto narrative recently has focused on Federal Reserve rate cuts and the rise of the Trump-era policy shifts, on-chain and macro data point to a different truth. This much simpler truth suggests that liquidity, not interest rates, has been the primary driver behind bitcoin’s major rallies and the broader market’s cycle peaks.
Bitcoin’s three largest historical uptrends have all shared a common pattern. Each one was largely motivated by increases in global M2 money supply or central bank balance sheet expansion. The memorable 2017 bull run that spanned about 12 months coincided with China’s credit boom and the Fed’s post-crisis liquidity, pushing BTC from $1,000 to nearly $20,000.
Liquidity drives crypto cycles, and now, the money has stopped flowing in

The 2020–2021 cycle exploded as the Fed’s over $3 trillion balance sheet injection in the face of growing COVID concerns flooded markets with capital, lifting BTC from $8,000 to $69,000. In 2024–2025, the most recent surge to $126,000 tracked the Fed’s rapid pivot from quantitative tightening to balance sheet stabilization, with M2 growth turning positive again after a two-year contraction.
This shows how the central bank balance sheet functions as a thermostat in the financial system, regulating temperature, or in this case liquidity, and affecting asset prices. The Federal Reserve’s balance sheet currently stands above $6 trillion, while the combined assets of the world’s four largest central banks, including the Fed, European Central Bank, Bank of Japan, and People’s Bank of China, now exceed $27 trillion.
In contrast, rate cuts alone have not reliably triggered rallies. The Fed’s 2020 emergency cuts occurred after liquidity injections had already ignited the market; the 2023–2024 cuts arrived while QT was still in force, and bitcoin traded sideways until the balance sheet pause. Analysts have tracked this divergence, noting that BTC price correlates at 0.82 with global liquidity metrics (including M2 and central bank assets) but only 0.41 with fed funds rate changes since 2017.
This is the most important chart you should pay attention to.

The current cycle fits perfectly into this pattern. Bitcoin peaked in October, following the Fed’s September shift away from tightening and the resumption of modest T-bill purchases, which injected fresh liquidity into risk markets. November’s 32% correction therefore aligned with renewed hawkish Fed projections and rising treasury yields, not rate levels themselves. As an analyst noted in their 2025 predictions, “crypto is a high-beta play on global liquidity conditions”, making it a proxy for risk-on capital flows more than monetary policy direction.
For 2026, the implication of this analysis is clear. Sustained rallies will require continued liquidity expansion, whether through Fed balance sheet growth, fiscal stimulus, or global M2 trends. Rate cuts without liquidity support tend to underwhelm and liquidity without cuts can still fuel powerful moves.
