The pace of global liquidity expansion is decelerating. For Bitcoin, that deceleration has a track record worth understanding.
What the Metric Measures
Global M2 Money Supply measures the total amount of money in circulation across major economies, including cash, checking deposits, and easily convertible near-money assets.
According to Alphractal report, the year-over-year change in that figure tracks whether the global money supply is expanding faster or slower than it was twelve months prior. When the rate of change is positive and rising, liquidity conditions are loosening. When it is positive but falling, as it is now, expansion is still occurring but at a decelerating pace. When it turns negative, the global money supply is actively contracting relative to the prior year.
The Alphractal chart tracking Global M2 year-over-year change against Bitcoin’s price from the early cycle through March 2026 shows this relationship across multiple halving cycles. The green shaded area above the zero line represents periods of positive year-over-year M2 growth. The red shaded areas below zero mark the periods where global liquidity contracted on an annual basis.
What the Chart Shows Historically
Reading the chart from left to right, the red zones below the zero line appear at specific points in each cycle. The first red zone coincides with an early period in Bitcoin’s price history when the asset was still establishing its initial market. The second, larger red zone appears in the middle section of the chart, aligning with the period following the 2017 to 2018 cycle peak. Bitcoin’s price, shown as the white line, declined significantly during and after that M2 contraction period. Red dashed arrows on the chart mark the moments where the year-over-year rate began turning downward from elevated levels, each preceding a period of Bitcoin price weakness.
The third red zone appears in the right section of the chart, corresponding to the 2022 bear market. Global M2 contracted year-over-year as central banks tightened aggressively in response to post-pandemic inflation. Bitcoin fell from above $60,000 to below $20,000 during that contraction period. The halving markers on the chart, shown as vertical dashed lines, provide the cycle context for each of these movements.
The current reading, marked by a red dashed arrow on the far right of the chart, shows the year-over-year rate turning downward from its recent peak near the $15 trillion level. Global M2 is still positive year-over-year, meaning the money supply is still larger than it was twelve months ago. But the pace of that expansion is slowing, and the direction of the rate of change has reversed.
The Connection to Bond Yields
The deceleration in Global M2 growth is directly connected to the bond yield dynamics covered in earlier reporting today. Rising yields across the US, EU, Australia, and Canada reflect tighter monetary conditions and higher borrowing costs globally. Higher borrowing costs reduce credit creation, which is one of the primary mechanisms through which M2 expands. The two readings are measuring the same underlying condition from different angles. Bond yields are rising and M2 growth is slowing because global liquidity conditions are tightening.
Bitcoin’s sensitivity to this dynamic is not incidental. As analyst Ash Crypto noted in earlier reporting, Bitcoin moves with liquidity. When global M2 expands, capital has more places to flow and risk assets benefit. When expansion decelerates or turns negative, the available pool of capital seeking returns contracts and the assets most dependent on new demand, rather than fundamental cash flows, feel it most directly.
What the Data Does Not Say
The Alphractal analysis is careful on the forward-looking framing. Reaching negative year-over-year territory from the current level could still take many months. In some scenarios it may not happen at all if global central banks pivot toward easing before the rate of change crosses zero. The metric is one to monitor over time rather than a signal that has already fired.
What the current reading does confirm is that the direction has changed. Global M2 growth peaked and has begun decelerating. That deceleration is consistent with the conditions that preceded prior Bitcoin cycle corrections, though the severity and duration of those corrections varied significantly depending on what other factors were present at the time. The data identifies a developing headwind. How far it develops from here is what the coming months will determine.
