The influence of a currency has traditionally been measured by its share of central-bank reserves, or by its use in international trade and the pricing of oil and other commodities. That measure is no longer enough. No matter how large the economy behind it, a currency cannot become a global power if it is difficult to move or lacks liquidity, safe assets, and widely accepted clearing and settlement networks. This is why the 2026 Jackson Hole Economic Policy Symposium matters well beyond the familiar question of where interest rates are heading.
Hosted by the Federal Reserve Bank of Kansas City from 27 to 29 August under the title “Financial Innovation: Implications for Payments and Policy”, the symposium devoted its programme to the infrastructure through which money moves: instant-payment systems, stablecoins, tokenised assets, central-bank digital currencies and the future of banking as platforms gain influence. The organisers described payment systems as “the circulatory system for the economy”. Currency ownership is not the only source of power. So too is the ability to set the rules under which money travels, see where it is going, and allow or block its passage.
The dollar’s strength does not rest solely on the size of the US economy or the depth of the Treasury market. It also derives from an interconnected system of correspondent banks, clearing houses, foreign-exchange markets, settlement systems, and legal and regulatory institutions. Swift plays a central role in this structure, but contrary to a common misconception, it neither transfers nor settles funds itself. It is a secure network through which financial institutions exchange messages and instructions. Settlement takes place through bank accounts and systems such as the US Fedwire Funds Service and the Clearing House Interbank Payments System, or CHIPS.
In retail payments, another layer of power lies with networks such as Visa and Mastercard. These companies do not themselves provide most of the credit involved, nor do they normally hold customers’ deposits. But they set the rules and standards that allow someone with a card issued by a bank in one country to pay a shop served by a bank in another. A single payment can therefore pass through several networks: one sends the instructions, another connects the card to the merchant, a third clears the transaction, and a further system completes final settlement in central-bank money. All this happens in seconds, beyond the customer’s view.
According to SWIFT data for May 2026, the dollar accounted for 59.1% of the value of international payments when transactions within the eurozone were excluded, compared with 13.9% for the euro and 2.2% for the Chinese renminbi. The figures do not cover every payment made worldwide, only the messages carried over SWIFT. Even so, they illustrate the gap between the weight of China’s economy and the international reach of its currency.
The more banks, companies and individuals join a network, the more useful it becomes and the greater the cost of leaving it. Over time, liquidity, expertise, trust and compliance rules gather around it. That is why the dollar’s dominance cannot easily be weakened simply by a group of countries agreeing to use their own currencies. A credible alternative requires a complete financial infrastructure capable of functioning every day, in normal conditions and in a crisis.

China builds a parallel route
China has not confined itself to calling for wider use of the renminbi in trade. It created the Cross-Border Interbank Payment System, or CIPS, which provides clearing and settlement services for renminbi-denominated transactions. By June 2026, it had 210 direct participants and 1,619 indirect participants. According to its operator, the payment-routing data services associated with CIPS cover more than 190 countries and regions and around 5,000 banking institutions. Not all of those institutions are formal CIPS participants, but the reach of services indicates the breadth of the system’s potential access.
Interest in this infrastructure grew after Western sanctions on Russia demonstrated that international financial networks cannot be divorced from politics. The power to exclude a bank or a country from payment channels has become one of the most consequential forms of pressure. CIPS, however, is not a Chinese version of SWIFT. The former clears and settles renminbi transactions; the latter is a global messaging network used for multiple currencies. Some activity on the Chinese system still relies on SWIFT messages, so competition between the two is accompanied by a degree of interdependence.
China also faces an obstacle technology cannot remove. An international currency needs to be freely convertible, backed by deep financial markets and safe assets that investors are willing to hold, and supported by a predictable legal framework. China’s capital controls therefore continue to limit the renminbi’s international reach, no matter how efficient its payment infrastructure becomes.
