Credit markets do not fail slowly. Liquidity gaps appear when dealer balance sheets shrink, redemption calendars cluster, or policy shifts repricing faster than investors can reposition.
Primary dealers hold less corporate and structured product inventory than they did a decade ago. When inventories fall, bid-ask spreads widen and off-the-run bonds trade with larger gaps to the curve.
Liquidity windows open when issuance is light, central banks inject reserves, or risk appetite returns after a volatility spike. Windows close when macro data surprises, funding costs rise, or forced selling hits the market.
Monitoring TRACE volume, dealer balance sheet trends, and ETF primary-secondary gaps gives a practical read on whether credit is trading in a supportive or fragile regime.
Investors who wait for perfect clarity often miss the window when spreads are widest but still compensating for risk. A process-based approach uses spread levels, maturity buckets, and relative value screens rather than macro calls.
Short-dated investment grade and selective high yield names can offer carry when liquidity returns, while longer spread product benefits from patience when balance sheet stress is building.
Liquidity windows in credit are cyclical and observable. Investors who track market depth, dealer behavior, and funding conditions can improve timing without pretending to forecast the next crisis.
