EM Settlement Cycles and Custody Frictions

In the US, a stock trade settles in one business day (T+1); the counterparty risk window between agreeing a trade and it actually clearing is short and standardized. Many emerging markets settle slower — T+2 or T+3 is common, and some frontier markets take longer still — which stretches the window during which a trade could fail, a counterparty could default, or a currency could move against an unsettled position. That gap is not a minor operational detail; it is a real source of risk that foreign investors must be compensated for taking on.

Custody in emerging markets typically requires a local sub-custodian — a domestic bank or broker that holds securities in-country, because many EM regulators require or strongly favour local custody of locally listed assets. This adds a layer between the investor and their assets: instructions must pass through a global custodian, to a local sub-custodian, into the local settlement system, and back, with each hop adding latency and a point of potential failure. Some markets add further friction through capital controls or repatriation restrictions, which govern not whether a trade settles, but whether the resulting cash can actually leave the country afterward.

These frictions show up in practice as wider effective bid-ask spreads, higher realized transaction costs than posted quotes suggest, and occasional failed trades around periods of local market stress — all reasons EM strategies typically build in larger cost buffers and more conservative position sizing around illiquid, longer-settlement names than a developed-market strategy would need.
