Global Liquidity Cycle Explained: Why Markets Follow Liquidity

Global liquidity is the aggregate amount of money circulating in the financial system — primarily measured through M2 money supply, central bank balance sheets, and cross-border dollar flows. It is a core macro variable tracked for asset price trends across classes, alongside rates, growth and positioning (data sources: central bank balance sheets, M2, cross-border flows; updated as published).

When central banks expand their balance sheets (quantitative easing, bond purchases, currency swaps), they inject liquidity into the system. This money doesn't just stay in reserves — it flows into equities, bonds, crypto, commodities, and real estate, inflating asset prices simultaneously.

The liquidity cycle follows a predictable pattern: expansion leads to rising asset prices and risk appetite (Risk-On), while contraction — through rate hikes, QT, or dollar strength — leads to asset price compression and risk aversion (Risk-Off).

The 2020–2021 bull run across all asset classes was driven by an unprecedented $8 trillion global liquidity injection. The 2022 bear market was driven by the fastest Fed tightening cycle in 40 years, draining liquidity. Understanding this mechanism gives traders a structural edge over those who focus purely on earnings or technicals.
