INTRO
You think you can sell. You think there’s cash. You think the pipes flow – you’re usually right.
Liquidity isn’t one thing -- it’s three.
Each layer works differently, carries its own risk.
Know all three – watch for signals.
TRANSACTIONAL LIQUIDITY – THE EXIT DOOR
Definition:
Your ability to turn an asset into cash -- fast, fair, no drama.
How it works:
A share of Apple. A Treasury bill. A gold coin.
Thousands of daily buyers and relatively tight spreads.
Simple -- until too many people rush for the same door.
When it broke:
March 2020. Markets tumbled, selling surged. “Liquid” assets -- even investment-grade bonds went “no bid.”
Bond ETFs traded far below fair value. The door shrank for everyone at once.
SYSTEMIC LIQUIDITY – THE MONEY SUPPLY
Definition:
The total stock of money circulating through the system -- controlled by central banks, government spending, and bank lending.
How it works:
The Fed prints reserves.
The government runs deficits -- spending money straight into the system.
Banks create loans -- new deposits appear out of thin air.
The tide rises, all boats float. The tide drops, same story in reverse.
When it broke:
When trust breaks, the flow of money stalls -- and the money supply dries up fast.
2008. Banks were “liquid” -- until lending froze, hoarding ruled, trust vanished.
More recently – the UK pension crisis showed how surprise collateral calls can drain liquidity overnight.
US Money Supply vs. S&P500 – liquidity lifts markets
FUNCTIONAL LIQUIDITY – THE PLUMBING
Definition:
The hidden network -- repo markets, collateral chains, global payments.
The Plumbing Maze – hidden connections, hidden risks.
How it works:
A maze of pipes connects banks, collateral, and payments.
Collateral loops, money moves cross-border, trust keeps it flowing.
One clog and the whole maze backs up.
When it broke:
Sept 2019. The overnight funding market (Repo) jammed up – and borrowing costs spiked to 10% in hours.
The Fed stepped in to keep the maze from seizing up.
THE FULL PICTURE
Liquidity isn’t one thing.
It’s your ability to sell. It’s the money flowing through the system. It’s the maze that keeps it moving.
See all three – that’s how money really moves.
