Answer
Usually no. Working capital management runs the operating cycle — receivables, payables, and inventory — so the business frees or consumes cash. Liquidity management is the cash stack: see balances, forecast, concentrate or fund gaps, invest surplus, and hold contingency. WCM changes how much cash the cycle produces; liquidity decides what to do with that cash. Full WCM frame: working capital management.
Why
- Different objects — WCM metrics are DSO, DPO, DIO / CCC and terms. Liquidity metrics are balances, forecasts, pool headers, lines, and buffers.
- Different owners — credit, procurement, and operations drive most WCM levers; treasury co-owns cash impact and policy. Liquidity structures (cash pooling, in-house bank, payment factory) sit with treasury.
- Sequence — fixing unallocated cash with virtual accounts or tightening payment runs can improve apparent working capital and feed the forecast (cash forecasting); that still does not replace a concentration design.
- Trapped cash — a great CCC in a corridor that cannot move funds is still a liquidity problem (cross-border cash pooling, China).
- Failure mode — treating “we need better liquidity” as only a pooling project ignores AR/AP; treating “we need better WCM” as only a CCC KPI ignores whether freed cash can be used.
