Bitcoin recently shattered the $100,000 barrier, peaking at $104,000 on May 8, reigniting discussions about its long-standing relationship with global liquidity—specifically, the 90-day lagged global M2 money supply. While the digital asset continues to defy skeptics, market analysts are revisiting a compelling narrative: Bitcoin’s price movements often mirror broader macroeconomic liquidity cycles, with a notable time delay.
This correlation isn’t new. It first gained traction during the 2021 bull run and has resurfaced repeatedly during pivotal market moments. Now, as global M2 begins a fresh upward trajectory—initiated in February 2025—the delayed reflection of this liquidity wave appears to be materializing in Bitcoin’s price action almost in lockstep.

The 90-Day Lag Theory: A Macro Lens on Bitcoin
The concept hinges on a simple premise: changes in the global money supply don’t immediately impact risk assets like Bitcoin. Instead, there's typically a 60- to 90-day delay as capital filters through financial systems, reaches investors, and eventually flows into alternative assets.
Julien Bittel, Head of Macro Research at Global Macro Investor, recently reinforced this idea on social media, stating the M2 vs. Bitcoin chart “still tells the same story: We’re going higher.” His analysis overlays Bitcoin’s price with the Global M2 Liquidity Index, adjusted for a three-month lag, revealing a striking visual alignment during key turning points.
CryptoSlate’s independent analysis confirms that while the correlation isn't perfect, it holds significant explanatory power—especially when viewed through the lens of global liquidity cycles rather than short-term price fluctuations.
Bitcoin doesn’t move in a vacuum. When central banks expand their balance sheets or ease monetary policy, the ripple effects take time to reach decentralized markets. That delay helps explain why Bitcoin often surges months after liquidity injections become visible in macro data.
Beyond Correlation: What’s Driving Bitcoin Now?
While the M2 narrative offers a compelling macro backdrop, it doesn’t operate in isolation. Several concurrent forces are propelling Bitcoin’s 2025 rally:
- Institutional inflows via spot Bitcoin ETFs
- Weakening U.S. dollar index
- Growing demand for decentralized alternatives amid trade-driven capital rotation
Over the past 10 weeks, Bitcoin recovered from a sub-$80,000 consolidation phase, fueled by consistent institutional appetite. In just three weeks, over $1.8 billion flowed into crypto investment products—with BlackRock’s IBIT leading the charge. On May 7 alone, the fund recorded a net inflow of $422 million, underscoring robust confidence from traditional finance players.
The U.S. dollar index has declined nearly 4% since late February, increasing the appeal of non-sovereign stores of value. As global capital reallocates toward higher-yielding or inflation-resistant assets, Bitcoin is increasingly seen as a viable hedge—particularly in an environment where stablecoins and decentralized finance (DeFi) expand access to digital liquidity.
Yet, it’s important to note: M2 metrics don’t capture stablecoin issuance or off-balance-sheet credit mechanisms. These blind spots mean the traditional money supply model provides only a partial view of total system-wide liquidity influencing crypto markets.
Testing the Limits: When the M2 Correlation Breaks Down
Despite its visual appeal, the 90-day lagged M2 model has limitations. A closer look reveals periods where the correlation weakens or even reverses.
Since the start of 2025:
- Global M2 has grown by 3.25%
- 90-day lagged M2 has declined by 0.16%
- Bitcoin has appreciated by approximately 8%
If Bitcoin were strictly following lagged M2, it should be down for the year. Yet it’s rising—suggesting other factors are overriding or accelerating the typical liquidity transmission mechanism.
Extending the timeline to 12 months paints an even starker picture:
- Bitcoin: +75%
- Global M2: +3.8%
- Lagged M2: +7.37%
Clearly, Bitcoin has vastly outperformed both real-time and lagged M2 growth. This divergence highlights that while liquidity sets the stage, market sentiment, regulatory clarity, and institutional adoption act as amplifiers.

FAQ: Understanding Bitcoin and Global M2 Dynamics
Q: What is M2 money supply, and why does it matter for Bitcoin?
A: M2 measures broad money supply, including cash, checking deposits, and easily convertible near money. It matters because increases in liquidity often precede investments in risk assets like Bitcoin—typically with a 60- to 90-day delay.
Q: Is the 90-day lag a reliable predictor of Bitcoin price movements?
A: It’s more of a trend indicator than a precise forecasting tool. While it has aligned with major turning points historically, short-term deviations are common due to regulatory news, macro shocks, or technical market behavior.
Q: Why did Bitcoin rise in early 2025 when lagged M2 was flat or declining?
A: Because other drivers—such as spot ETF inflows, geopolitical uncertainty, and dollar weakness—overpowered the liquidity signal. Bitcoin increasingly reflects a blend of macro and crypto-native factors.
Q: Does this mean Bitcoin is decoupling from traditional markets?
A: Partially. While still influenced by macro trends, Bitcoin is showing stronger independent momentum—especially as adoption grows in decentralized finance and cross-border payments.
Q: Can we expect Bitcoin to keep rising if M2 continues to grow?
A: Persistent liquidity expansion increases the likelihood of continued upside, but only if accompanied by strong on-chain fundamentals and investor confidence.
Q: Are there risks to relying too heavily on the M2 correlation?
A: Yes. Overreliance ignores structural shifts in crypto markets—like stablecoin dominance, regulatory changes, or technological upgrades—that can disrupt historical patterns.
The Bigger Picture: Liquidity Meets Adoption
Bitcoin’s current position near $103,000 reflects more than just speculative enthusiasm. It represents a confluence of favorable macro conditions and accelerating institutional adoption. The rolling 180-day Pearson correlation between Bitcoin and lagged M2 has averaged 0.65 since early 2024, indicating a moderate-to-strong relationship over medium-term horizons.
However, 30-day correlations swing wildly between -0.9 and +0.95, underscoring high volatility and sensitivity to immediate news cycles. This reinforces the idea that while global liquidity sets the foundation, day-to-day price action is shaped by sentiment, regulation, and technological progress within the ecosystem.
As central banks continue signaling accommodative policies and inflation remains structurally elevated in many regions, the path of least resistance for risk assets—including Bitcoin—appears upward.

Final Thoughts: A Fluid but Powerful Narrative
The 90-day lagged M2 model remains one of the most visually compelling frameworks for understanding Bitcoin’s long-term trajectory. It won’t predict exact tops or bottoms—but it does offer valuable context about the tide beneath the waves.
Bitcoin isn’t merely following money supply; it’s evolving into a global liquidity sink—a digital reserve asset that absorbs excess capital when traditional markets falter. Whether this surge sustains depends not just on how much money is printed, but how effectively it flows into digital ecosystems through regulated gateways like ETFs and compliant exchanges.
For now, the message is clear: liquidity matters, but adoption amplifies it.
