Net Liquidity Z-Score
A statistical normalisation of the Federal Reserve's effective market liquidity — defined as Fed Balance Sheet minus Treasury General Account (TGA) minus Overnight Reverse Repo (RRP) usage. The Z-score expresses current conditions relative to a 25-year rolling mean, capturing whether the system is in structural liquidity expansion or contraction regardless of the absolute dollar level.

Neutral Liquidity Regime. Market returns likely driven by earnings rather than monetary plumbing.

Z = (Net Liquidity − μ₂₅ᵧ) / σ₂₅ᵧ where Net Liquidity = WALCL − WTREGEN − RRPONTSYD
Why It Matters
Historically, S&P 500 returns correlate strongly with changes in Net Liquidity. A Z-score above +1.5 has preceded bull phases; below −1.5 has preceded corrections. Institutional PMs use this as a regime-detection overlay on all other signals.

Treasury General Account (TGA)
The US government's primary operating account held at the Federal Reserve Bank of New York. TGA balances rise when the Treasury collects taxes or issues debt, draining dollars from the banking system. They fall when the government spends, injecting liquidity back. The TGA is therefore a structurally important off-balance-sheet liquidity lever for the Fed.Overnight Reverse Repo Facility (ON RRP)
A Federal Reserve tool allowing eligible counterparties (primarily money market funds) to park excess cash overnight with the Fed in exchange for Treasury collateral. RRP balances peaked at ~$2.55 trillion in 2022 as money funds parked excess reserves. As RRP drains toward zero, that liquidity re-enters the financial system — the structural "hidden QE" of 2023–2024.Carry Trade
A leveraged trading strategy of borrowing in a low-interest-rate currency (the "funding" currency) and investing in a higher-yielding currency or asset. The profit — the "carry" — is the interest rate differential minus currency risk. The unwinding of large carry trades (particularly JPY-funded) can trigger acute global risk-off episodes as positions are sold simultaneously.Ready to see this live?
