Derive a placement from genuinely available surplus

For a placement that locks principal until T, begin with usable cash and every relevant cash need before T. Under a deterministic plan with no borrowing or sale of the placement, the maximum principal that can be locked is the smallest surplus above the required reserve over that interval, capped by cash actually available at placement. Include charges paid now and other committed uses. A forecast average balance can be positive while one intervening date has no investable surplus.

Assess the uncertainty that matters for access. If an essential outflow can arrive earlier or a receipt can arrive later, use the permitted protection or separate scenarios from FIN.2. A ladder of maturity dates can meet different cash needs where actual instruments permit it. Retaining immediately usable cash can be preferable to committing all of a modeled surplus. A higher yield does not repair a maturity or access mismatch.

Then compare actual permitted instruments and providers. Distinguish contractual repayment from a market sale, a demand withdrawal from a notice period, and expected value from principal guaranteed under an applicable arrangement. A security described as liquid may need to be sold at a changed price; a fund’s access can depend on dealing deadlines and redemption conditions. A deposit remains a claim on its provider. Obtain any relied-on guarantee or protection conditions rather than infer them from an instrument label.

Compare net return on the same principal, dates and risk grounds, including custody, transaction charges, withdrawal penalties and funding consequences. Evaluate concentration with other balances and claims on that provider. An otherwise attractive new deposit may put both the corporation’s operating payment access and most of its cash at the same point of failure. The remedy can be a different feasible provider or retained liquidity, subject to actual access and mandate.

The output for a routine placement is therefore an executable amount, instrument, counterparty, maturity or withdrawal arrangement and accepted conditions. Reopen the financial choice when a new term would change the intended preservation, liquidity or risk of the cash.
