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.
