Dollar reserve, clearing and asset infrastructure

Dollar reserve, clearing and asset infrastructure combines the United States currency, deep securities markets, official and private custody, correspondent banking, Fedwire, CHIPS, foreign-exchange markets and sanctions compliance. Its scale supports global liquidity and gives public authorities leverage at particular jurisdictional and network nodes. It is not one machine, and dollar denomination alone does not establish United States jurisdiction.

Different functions and systems

A reserve asset, invoice currency, funding currency, payment currency, message network, clearing system, settlement system and custody arrangement perform different functions. The dollar's prominence across several of them creates network effects, but no single percentage measures the whole system.

The International Monetary Fund's COFER data measure the currency composition of allocated official foreign-exchange reserves. COFER excludes gold and unallocated reserves and does not identify every holder or Treasury position. For the first quarter of 2026, the dollar represented 57.13 per cent of allocated reserves, with valuation effects identified by the IMF.

The Bank for International Settlements found that the dollar was on one side of about 89 per cent of foreign-exchange transactions in April 2025. Currency shares in that survey sum to 200 per cent because each trade has two currencies. The figure is not a claim that the dollar holds 89 per cent of a denominator summing to 100.

Messaging, clearing and custody

SWIFT is a Belgian cooperative providing secure financial messaging. It does not issue dollars, hold customer funds or itself clear and settle the underlying payment. A SWIFT restriction and a restriction on funds, accounts or settlement access are therefore different acts.

Fedwire Funds Service and CHIPS are separate dollar systems with different ownership, participants and operating models. Correspondent banks connect customers and institutions to payment paths. The Federal Reserve Bank of New York also provides account, custody and transaction services for eligible official institutions. A claim about access or denial must identify the actual system and account relationship involved.

Statecraft and jurisdiction

United States authorities can use sanctions designations, transaction prohibitions, correspondent-account restrictions, Section 311 measures and other legal tools. These instruments have different authorities, tests and effects. Regulated banks, clearing systems and custodians transmit many restrictions, while official systems can also provide liquidity and market support.

Significant dollar activity does not automatically touch United States jurisdiction. The parties, accounts, payment and custody path, clearing leg, governing law, applicable prohibition and statutory nexus must be proved for each transaction.

Immobilisation of Russian central-bank reserves was a coalition and multi-currency custody action involving several jurisdictions, custodians and legal authorities. It was not solely a United States seizure through dollar clearing. Any aggregate figure must name the authority, date, exchange-rate convention and whether it describes assets identified, immobilised or held in a particular jurisdiction.

Reserve diversification, local-currency settlement, alternative messaging and gold accumulation can reduce selected exposures but do not reproduce the dollar system's liquidity and market depth automatically. A general state strategy to preserve or destroy dollar dominance remains contested unless a public act states it.

The record remains in the main sequence because governments repeatedly use defined monetary, legal and network nodes for provision, restriction, asset control and denial.
