Bitcoin’s M2 money supply correlation and gold divergence

The M2 Disconnect

Bitcoin trades at $74,000, which is a 46% gap from its $136,000 fair value based on global M2 money supply models. The relationship between Bitcoin and the global M2 money supply involves a 4-year correlation that typically stays between 0.4 and 0.6, but this connection broke down when global M2 grew by 12% while Bitcoin fell by 12% over the last twelve months. Bitcoin’s M2 beta is 11.3, but the R-squared value fell to 0.59. This shift differs from the 2022 bear market when the R-squared stayed between 0.71 and 0.90 during M2 contraction. In 2020, an 8% surge in M2 over six months drove an 11.5% gain in gold and an 8.5% gain in Bitcoin. During the 2022 period, a 2.7% M2 contraction led to a 52.4% drop in Bitcoin. Currently, the Bitcoin Z-score relative to its M2 fair value hit negative 1.31 in February 2026, while gold’s Z-score reached 2.82. A set of proposals from the Fed, OCC, and FDIC would lower bank capital requirements by nearly 5% for large institutions and 8% for smaller banks. These changes increase a bank’s capacity to extend credit, which expands M2 through a primary lending channel. Goldman Sachs data shows the three-month correlation between Bitcoin ETFs and non-profitable tech stocks reached 0.78, which is the 97th percentile since December 2014.

The Gold Divergence

Gold reached a record high of $5,589 per ounce on January 28, 2026, after gaining 80% since the start of 2025. Bitcoin shed 20% this year after it peaked at $126,000 in October 2025. The Bitcoin-to-gold correlation coefficient hit -0.88 in March 2026, which is its lowest level since the 2022 bear market. This negative correlation proves that the two assets no longer move in the same direction. Gold captured the liquidity bid that historically flowed to Bitcoin. The U.S.-Iran conflict that began February 28 sent energy prices above $100 and increased inflation risks. I would say the "digital gold" thesis failed to protect investors against the sudden market panic caused by this geopolitical shock. Bitcoin is exceptional at protecting purchasing power in emerging markets facing fiat collapse, such as its 90% appreciation against the Argentine peso in 2024, but it fails during sudden market panics. Gold trades near $4,700 per ounce, which is 13% below its all-time high. Central banks expect to buy 755 tonnes of gold this year as they move away from dollar-heavy reserves. Global gold ETFs attracted $19 billion in inflows in January 2026. The World Gold Council confirmed that gold posted over 50 all-time highs in 2025. Goldman Sachs has a year-end 2026 target of $4,900 per ounce, while J.P. Morgan sees prices pushing toward $5,000. Does the massive institutional shift into gold mean Bitcoin’s role as a monetary hedge has permanently changed?

The Fed and Rate Cuts

The Federal Reserve kept rates at 3.50 – 3.75% in March 2026, which sent Bitcoin down 5% to $71,100. A 50 basis point cut now changes the liquidity math for the remaining months of the year. Monthly Bitcoin returns and changes in the Fed funds rate show a correlation of -0.04. This figure is statistically indistinguishable from zero. A regression of monthly Bitcoin returns on rate changes puts the coefficient at -0.02% per basis point. This implies a standard 25 bp Fed move only associates with -0.5% of Bitcoin return in the same month. I found that Bitcoin performed best during the 2015 – 18 hiking cycle and the 2023 – 24 period when rates sat at 5.25 – 5.50%. The 2022 – 23 hiking cycle saw Bitcoin fall from $47,000 to $15,500 as the Fed raised rates 11 times. In March 2026, spot Bitcoin ETF outflows reached $708 million in a single day. Most scheduled FOMC decisions are priced in by fed funds futures before the announcement happens. The correlation between Bitcoin and the US dollar ranges from -0.6 to -0.8, so a stronger dollar often accompanies a weaker Bitcoin price.

The Portfolio Strategy

Investors use a barbell approach to manage these diverging assets. This strategy involves a 10 – 15% allocation to gold for crisis insurance and a 5 – 10% allocation to Bitcoin for liquidity expansion and technology adoption.

US spot Bitcoin ETFs accumulated over $53 billion in net inflows since January 2024. This accumulation pace exceeded the speed at which gold ETFs reached their historical levels. The average ETF investor cost basis entering 2026 is near $84,000 per coin, compared to a trading price near $75,000. This means many ETF holders remain underwater on paper. Bernstein projects Bitcoin reaching $150,000 in 2026 and $200,000 in 2027. MicroStrategy could purchase roughly $30 billion worth of Bitcoin in 2026 alone. BlackRock’s iShares Bitcoin ETF accounted for $1.7 billion of the $2 billion in inflows recorded across four consecutive weeks earlier this year. JPMorgan analysts noted that BlackRock’s iShares Bitcoin ETF inflows since 2024 are roughly double the inflows for the SPDR Gold Shares ETF over the same period. If you are holding Bitcoin, size your position to what your portfolio can absorb if the asset corrects another 30% before the next leg up.
