What Is Global Liquidity?
Global liquidity refers to the total amount of money and credit available in the world financial system, measured by metrics like aggregate central bank balance sheets, M2 money supply, and global credit growth. When central banks inject liquidity (QE, rate cuts), risk assets including crypto benefit from the flood of capital seeking returns. When they withdraw it (QT, rate hikes), risk assets suffer.
How Global Liquidity Works
Global liquidity is the sum of all major central banks' actions: the Fed, ECB, BOJ, PBOC, BOE, and others. The aggregate matters more than any single bank because capital is global. China's PBOC injecting liquidity can offset some of the Fed's tightening. The Net Global Liquidity Index tracks this aggregate and has shown strong correlation with Bitcoin's macro price trend.
Why It Matters for Traders
Bitcoin is the highest-beta liquid asset relative to global liquidity. When the global liquidity cycle turns up, Bitcoin tends to lead risk assets higher. When it turns down, Bitcoin leads lower. Tracking the rate of change in global M2 money supply (not just the level) has been one of the most reliable macro indicators for timing Bitcoin's multi-month trends.
