Settlement And Why Money Takes Days To Move

A share trade is agreed in a fraction of a second, yet the shares and the money change hands days afterwards. The delay is deliberate and reflects work that has to happen in between.

Execution and settlement are separate events

Execution is the moment the price and quantity are agreed. Settlement is the moment the securities move to the buyer and the cash moves to the seller.

Between the two, the trade exists as an obligation on both sides. Legal ownership has not yet transferred and the registers have not been updated.

The interval is expressed as a number of business days after the trade date, and the standard has shortened over the years as processing has become more automated.

Clearing sits in the middle

A clearing house typically interposes itself between buyer and seller, becoming the counterparty to each. Neither side depends on the other performing.

It also nets obligations, so a firm trading many times in one security settles a single net position rather than every individual trade.

Netting reduces the volume of movements enormously, which is a large part of why settlement systems can handle the volumes they do.

Margin protects the interval

Because time passes between agreement and settlement, prices can move against one side. The clearing house collects collateral to cover that exposure.

Margin requirements rise when markets become volatile, since the potential movement over the settlement period is larger.

This is why volatile conditions increase the funding demands on brokers, and why some restrict certain activity when those demands rise sharply.

The delay has practical consequences

Proceeds from a sale are not available immediately, which matters when money is needed by a specific date or when switching between holdings.

Entitlements such as dividends depend on being the registered holder on a record date, which is determined by settlement rather than by the trade date.

Corporate action deadlines work the same way, so a purchase made shortly before a cut-off may not confer the entitlement the buyer expected.

Fund dealing follows a different rhythm

Open-ended funds price once a day at a valuation point, and the deal is struck at a price calculated after the order deadline rather than at a live quoted price.

Settlement then follows on its own timetable, which can be longer than for exchange-traded securities and varies between fund types.

Settlement conventions differ between markets and instrument types and continue to change, so the timetable that applies is the one published for the specific holding and venue.
