Hong Kong-listed OSL Group says Banking Circle now supports its institutional payment operations in six fiat currencies, adding Australian dollars, British pounds, Hong Kong dollars, Singapore dollars and US dollars to an existing euro arrangement. The companies described the expansion in a September 15 announcement.
Banking Circle will provide infrastructure for fiat settlement, cryptocurrency conversion and liquidity management across OSL’s business platforms. The announcement identifies supported currencies but does not disclose transaction volumes, fees, eligible corridors or when each service became available to individual clients.
Six fiat currencies across business payment rails
The added currencies are AUD, GBP, HKD, SGD and USD; EUR was already supported. OSL described the arrangement as a way to connect institutional clients to payment rails as its business solutions expand across markets. It did not say that it had issued stablecoins in each of the six currencies. The currency list refers to Banking Circle’s support for OSL’s fiat-facing payment infrastructure.
OSL said it would use Banking Circle’s BC-Now instant-payment network in the expanded relationship. The companies describe that network as operating around the clock and say it can help clients receive, convert and settle funds through one business platform. These are company descriptions of the planned operating model, not independently published measurements of end-to-end settlement time in all six currencies. Local bank cutoffs, destination rails, client eligibility and regulatory requirements may still affect a given transaction.
Institutional scope and regulatory limits
OSL’s release points to growing business interest in moving between fiat money and stablecoins. The new announcement concerns banking and payment connectivity, not a new public stablecoin issue or a retail product launch. It also does not identify the specific stablecoins involved in the expanded rails.
The company said its Austrian subsidiary, OSL EU, recently received authorization as a crypto-asset service provider under Europe’s Markets in Crypto-Assets rules. That authorization does not itself establish the legal status of every OSL product in every country. OSL’s release says its Hong Kong communication is directed at professional investors and notes that certain issuers and OSLDS are not licensed under Hong Kong’s Stablecoin Ordinance to conduct regulated stablecoin activities. OSLDS says it is a permitted offeror that limits the referenced products and services in Hong Kong to verified professional-investor clients.
Banking Circle is a Luxembourg-headquartered credit institution. Its earlier description of stablecoin settlement services sets out its institution-facing approach to combining payment accounts and digital-asset settlement. The companies have not provided an independently audited measure of how much the OSL expansion changes settlement costs, speed or client reach.
