Visa Joins Singapore's BLOOM to Test Settlement That Never Closes

Visa said on Tuesday that it has joined BLOOM, an initiative led by the Monetary Authority of Singapore to make traditional payment systems and stablecoin rails work together. Its first partner under the programme is Nium, the cross-border payments firm, and together they will pilot something deceptively simple: settlement that runs seven days a week.

BLOOM stands for Borderless, Liquid, Open, Online, Multi-currency. MAS launched it in late 2025 to host trials involving tokenised bank liabilities and regulated stablecoins. Visa's participation is its first project inside the framework, and the pilot will support regulated stablecoins backed by major currencies, including US dollar and euro-denominated tokens.

The problem is the calendar, not the technology

When money crosses a border today, two different things happen at two different speeds. The instruction moves quickly. Settlement — the part where institutions actually square what they owe each other — follows the business-day calendar. Weekends and public holidays are not settlement days, so obligations queue up and wait.

That gap is where the friction lives. A payment initiated on Friday evening may not settle until Monday or Tuesday, which means the receiving institution cannot access the funds and the sender's money sits in a state that is neither sent nor arrived. Visa described the objective plainly: reduce delays, improve efficiency, and give participating financial institutions faster access to funds.

Stablecoins do not care what day it is. A regulated dollar token moves at 3am on a Sunday exactly as it moves at 10am on a Wednesday. If the settlement leg runs on that rail, the calendar constraint disappears — without changing anything about how a person pays at a checkout.

This builds on work already running

The pilot is not starting from zero. Nium joined a wider Visa stablecoin settlement pilot in November, under which it settles with Visa using stablecoins including Circle's USDC. The BLOOM trial narrows that to a specific question: can regulated stablecoins carry cross-border settlement obligations across weekends and public holidays, under a central bank's supervision, with existing compliance and security controls left intact?

That last clause is the part worth noticing. The framing is not “replace the banks.” MAS designed BLOOM to connect existing payment systems to stablecoin rails while preserving the safeguards that make institutions willing to use the system at all. Visa is contributing its network, security and compliance capabilities rather than routing around them.

What is still unknown

A fair amount, and it is worth being honest about that. Neither company has announced a launch date, named which financial institutions might join beyond themselves, or disclosed expected transaction volume for the trial. The framework and the objectives are public; the operational specifics are not. This is an early-stage pilot and should be read as one.

What makes it significant is less the pilot itself than the pattern it belongs to. Card networks are no longer experimenting with stablecoins at the edges of their business. They are testing them in settlement — the least glamorous, most load-bearing part of the stack.
