Foreign Exchange Settlement Tests Its On-Chain Future
Payment-versus-payment settlement on shared ledgers is moving from proofs of concept to scheduled operations in a handful of currency corridors.
Wikimedia Commons · CC BY 2.0The oldest risk in foreign exchange is paying away one currency before receiving the other. Shared-ledger settlement attacks that risk directly, exchanging both legs of a trade in a single atomic step, and the approach is graduating from demonstrations to scheduled settlement windows in several currency corridors.
Adoption follows the pain. Corridors with time-zone gaps and thin correspondent coverage benefit most from atomic settlement, and it is there, rather than in the deepest major pairs, that volume is materializing first. Participants describe the economics as straightforward: settlement risk that once required credit lines and buffers simply does not exist for the settled portion.
The constraint is participation. Payment-versus-payment only works when both sides operate on connected infrastructure, which makes each new bank that joins more valuable than the last. The network math that built the incumbent settlement utilities is now working, slowly, for their successors.
