Liquidity

The ease with which an asset can be bought or sold quickly at a fair price, and more broadly, the availability of money and credit throughout the financial system.

Liquidity has two related meanings in finance. Asset liquidity refers to how quickly and cheaply a specific security can be converted to cash. Highly liquid assets — large-cap US stocks, Treasuries, gold — can be sold in large quantities with minimal price impact. Illiquid assets — small-cap stocks, private equity, real estate — may take days or months to sell, often at a significant discount.

Market liquidity is broader: it describes the overall availability of credit and cash in the financial system. When central banks cut rates or conduct QE they add liquidity, lowering borrowing costs and encouraging risk-taking. When they raise rates or tighten conditions, liquidity drains. Liquidity crises — like 2008 or briefly in March 2020 — occur when participants lose confidence in each other and stop transacting, causing prices to disconnect from fair value.

Liquidity profoundly affects asset prices. Assets in illiquid markets trade at a "liquidity discount" relative to comparable liquid assets — investors demand higher returns to compensate for inability to exit easily. During stress, even normally liquid assets can become hard to sell without large price concessions, a phenomenon known as "liquidity evaporating."
