What this is
The marketing label reads "flexible" or "any-time withdrawal," yet the product attaches conditions at the redemption side: a notice period of some hours or days, a structural settlement lag, or explicit T+N language in the terms. Liquidity in practice resembles a fixed-term product. Pennyworth classifies on the redemption-delay side and surfaces this trap to flag the gap with the marketing label.
What it means for you
A user who slots this product into a true-flexible bucket for cash management will run into the notice period or settlement lag at the moment of need. The trap does not cost principal or interest, but the liquidity assumption will fail to hold. Positions intended for active rotation should not use this product; positions held for the medium to long term can absorb the constraint.
In practice
A CEX product marketed as "7-Day Flexible Savings" with terms stating that redemption arrives at T+7. The product is functionally a 7-day fixed deposit. Principal is intact and interest accrues as advertised, but the liquidity profile is not what the label implies: any cash-need decision made on the assumption of instant withdrawal will land seven days late.
