Bitcoin and S&P 500 show weakness when adjusted for money supply
In brief
- Bitcoin dropped 48% from $126,000 October 2025 peak to $66,000
- M2-adjusted S&P 500 only recently reclaimed 2000 inflation-adjusted highs after 25 years
- Bitcoin BTC/M2 ratio forms bearish head-and-shoulders pattern, signaling diminishing real gains
- May crypto volumes fell 3.45% to $4.41T, lowest since September 2024
The M2 Reality Check
M2 is the Federal Reserve's estimate of liquid assets, including cash on hand, money deposited in checking and savings accounts, and short-term saving vehicles such as money market funds and certificates of deposit. It's a measure of how much new money has flooded into the system. Strip that growth away, and asset prices tell a humbler story.
The S&P 500 currently hovers near a record high of 7,511 points, well above its 2000 peak of around 1,500 points in nominal terms. But when adjusted for two decades of M2 growth, the S&P 500 has only recently reclaimed that 2000-era high. It has taken a quarter-century of money-supply expansion just to get the index's monetary-adjusted valuation back to where it stood at the height of the dot-com bubble.
Bitcoin's Structural Weakness
Bitcoin's story is bleaker. The BTC/M2 ratio, measuring bitcoin's price adjusted for money supply growth, has formed what technical analysts call a head-and-shoulders pattern, typically interpreted as a bearish signal. The ratio climbed sharply from 2023 through 2025 but now shows signs of reversal.
Bitcoin's ability to outpace the flood of new dollars may be approaching diminishing returns, at least for now. This matters because Bitcoin has at times been viewed as a leading indicator for broader risk appetite. When the most liquidity-sensitive asset in the room shows structural weakness, it warrants attention.
Volume and Divergence
The broader crypto market reflects this strain. In May, combined exchange volumes fell 3.45% to $4.41 trillion, the lowest since September 2024. One notable exception: RWA perpetual futures volumes rose 10.4% in May, hitting a new all-time high, suggesting traders are rotating into real-world asset exposure even as traditional crypto liquidity dries up.
The divergence underscores a broader truth. Nominal price charts obscure the real erosion of purchasing power baked into decades of monetary expansion. Both Bitcoin and equities face a structural challenge: outpacing the money printer itself.
Frequently asked questions
What is M2 and why does it matter for asset valuations?
M2 is the Federal Reserve's measure of liquid money supply—cash, checking/savings deposits, and short-term vehicles like money market funds. It matters because stripping M2 growth from nominal prices reveals whether asset gains reflect genuine productivity or merely monetary expansion. When both Bitcoin and the S&P 500 struggle to beat M2-adjusted benchmarks, it suggests real purchasing power may be eroding.
Why is Bitcoin's BTC/M2 ratio important?
The BTC/M2 ratio measures Bitcoin's price adjusted for money supply growth. Bitcoin's ratio has formed a bearish head-and-shoulders pattern after climbing sharply from 2023-2025, signaling that Bitcoin may be losing its structural ability to outpace dollar inflation. This is concerning because Bitcoin is often viewed as a leading indicator for broader risk appetite.
Has the S&P 500 really gained since 2000?
In nominal terms, yes—the S&P 500 rose from around 1,500 in 2000 to a record 7,511 today. But when adjusted for 25 years of money-supply expansion, the index has only recently reclaimed its 2000-era valuation. This means the dot-com bubble peak and today's prices are roughly equivalent in real terms.
