Dollar Liquidity

The aggregate stock of USD funding available to the global financial system — driven by Fed reserves, RRP, the Treasury General Account, and SOMA holdings.

Definition

Dollar liquidity is the net flow of USD reserves into the system. It expands when the Fed grows its balance sheet or the Treasury runs down its TGA; it contracts during QT, TGA refills, and reserve drains.

The most common composite proxy is Net Liquidity = Fed Assets − TGA − RRP, which strips out the components that don't add to bank reserves.

Why it matters

Dollar liquidity is the dominant macro driver of risk-asset valuations over 3–12 month horizons. Equity multiples track it closely.

Worked example

2023: TGA rebuild after the debt-ceiling resolution drained ~$700B of net liquidity, coinciding with the SVB stress and a credit-spread spike.

Frequently asked

How fast does dollar liquidity move markets?⌄
Bonds and FX react in days; equities take weeks; private markets take quarters.
What's the TGA's role?⌄
The Treasury General Account is the government's checking account at the Fed. Rising TGA drains reserves; falling TGA adds them.
Is M2 the same as dollar liquidity?⌄
Related but not identical. M2 measures deposits; dollar liquidity measures the Fed-controlled supply of reserves.
How does QT reduce liquidity?⌄
The Fed lets bonds mature without reinvesting; the Treasury must reissue to private buyers, draining reserves.
