If there is one variable that explains more of the variance across global asset prices than any other, it is liquidity. The total amount of money sloshing around the global financial system drives everything from US equities to Chinese real estate to Bitcoin.
Global liquidity is measured in various ways, but the most comprehensive metrics include central bank balance sheets, credit creation by commercial banks, and cross-border capital flows. When these measures are expanding, there is more money chasing assets, and prices tend to rise across the board. When they are contracting, the opposite occurs.
The M2 money supply across major economies (US, Europe, China, Japan) provides a useful aggregate liquidity measure. When global M2 is growing, it creates a favorable tide that lifts most asset prices. Bitcoin in particular has shown a strong correlation with global M2 growth, with a lag of approximately 2-3 months. This makes sense because new money creation takes time to flow through the banking system and into financial markets.
Central bank balance sheet changes are the most powerful component of liquidity flows. Quantitative easing (QE) directly injects liquidity by purchasing bonds, which puts cash into the financial system. Quantitative tightening (QT) does the reverse. The Fed, ECB, BOJ, and PBOC together determine the global liquidity tide, and their combined balance sheet direction is arguably the single most important variable for all risk assets.
Cross-border capital flows add complexity. The dollar recycling mechanism, where US trade deficits send dollars abroad and those dollars are reinvested in US financial assets, creates a self-reinforcing liquidity cycle. Disruptions to this cycle (like trade wars or geopolitical tensions) can create unexpected liquidity shortfalls.
The reverse repo facility and Treasury general account (TGA) at the Fed are often overlooked liquidity factors. When the TGA is being drawn down (government spending more than it is collecting in taxes), it adds liquidity to the system. When the TGA is being built up (through tax collection or new bond issuance), it drains liquidity. These plumbing-level dynamics can move markets independently of headline monetary policy.
For crypto, liquidity is arguably the most important macro variable. The crypto bull runs of 2017,2020-2021, and subsequent cycles have all coincided with periods of abundant global liquidity. The 2022 bear market coincided precisely with the most aggressive liquidity tightening in decades. If you get the liquidity direction right, you get the crypto direction right more often than not.
Building a liquidity dashboard that tracks central bank balance sheets, M2 growth, credit impulse, and plumbing indicators (reverse repo, TGA) provides a framework that is more useful for medium-term crypto positioning than any technical indicator. The liquidity tide determines whether your technical setups work in your favor or against you.
