X Change: Stablecoins move deeper into payments and credit

X Change is your weekly briefing from BetterX & AUDX on the developments shaping digital assets, stablecoins and financial infrastructure.

This week:

• Stablecoin infrastructure expanded well beyond simply issuing digital dollars.
• Circle moved to acquire a cross-border payments platform.
• Visa introduced an on-chain credit model for stablecoin-linked card programs.
• Tether launched a private credit fund that will use USDT in cross-border lending.
• PayPal expanded its stablecoin infrastructure to support customised tokens backed by PYUSD.
• Banks in Singapore continued testing how tokenised deposits could support payments outside traditional banking hours.
  

Here's what caught our attention this week.

💳 Payments Watch

Circle agrees to acquire Singapore-based payments platform Tazapay

Circle has signed a definitive agreement to acquire Tazapay, a Singapore-headquartered B2B cross-border payments infrastructure company serving payment providers and financial institutions.

Tazapay brings more than 60 banking and fintech partners, local payout capabilities across 100+ markets and more than US$25 billion in annualised payment volume.

According to Circle, approximately 60% of Tazapay’s transaction volume already involves stablecoins.

The transaction is expected to close in 2027, subject to customary conditions and regulatory approvals, including approval from the Monetary Authority of Singapore.

Why it matters

Stablecoin adoption depends on more than the token itself.

To become useful in payments, stablecoins need the banking relationships, local payout rails, liquidity and compliance infrastructure required to move between on-chain money and traditional currencies.

Circle’s proposed acquisition shows the stablecoin infrastructure race increasingly shifting towards distribution and payment connectivity.

For companies operating across Asia-Pacific, that is particularly relevant: the challenge is not simply moving a stablecoin on-chain, but getting value efficiently into and out of local markets.

💳 Stablecoins & Payments

Visa brings on-chain lending into stablecoin-linked card programs

Visa announced a new approach to on-chain credit designed to help fintechs and stablecoin-linked card programs access working capital.

The model combines VisaNet settlement data with blockchain-based lending infrastructure, giving participating lenders more information with which to assess financing and extend capital.

Visa says more than 160 stablecoin-linked card programs are now live across its network. Payment volume on those programs grew nearly 200% year on year, while Visa’s stablecoin settlement volume recently passed a US$20 billion annualised run rate.

Visa also highlighted an existing model with Credit Coop that has supported more than US$2.5 billion in cumulative financed settlement volume since 2023.

Why it matters

Payments infrastructure requires working capital.

A card program may need to fund settlement before it receives money from its customers, which can create a financing gap as programs grow.

Visa is now exploring how blockchain-based lending can help finance that gap.

That is an important evolution in the stablecoin story: the ecosystem is moving beyond simply sending money and beginning to build the credit, liquidity and treasury infrastructure required to support payments at scale.

🪙 Stablecoin Watch

Tether and Fasanara launch US$400 million private credit fund

Tether and London-based asset manager Fasanara Capital have launched StableFund, an evergreen private credit vehicle anchored by US$400 million in co-investment from the two sponsors.

The fund aims to attract up to US$3 billion in third-party institutional capital.

Fasanara will manage the fund and deploy capital through fintech lending platforms, while Tether will help source USDT-related financing opportunities and provide stablecoin infrastructure for moving capital across borders.

The strategy is focused on financing small and medium-sized businesses and other borrowers through lending networks operating across multiple markets.

Why it matters

This extends the role of a stablecoin beyond payments and settlement into credit markets.

If stablecoins can efficiently move capital between investors, funds and borrowers across jurisdictions, they could become part of the underlying infrastructure supporting private-market financing.

It is also another example of the boundaries between crypto-native infrastructure and traditional financial products becoming less distinct.

🏗️ Stablecoin Infrastructure

PayPal launches infrastructure for businesses to create customised stablecoins

PayPal has expanded its stablecoin strategy with PYUSDx, a platform that allows businesses to launch customised stablecoins backed by PayPal USD (PYUSD).

The platform was developed with digital-token infrastructure provider M0 and payments company MoonPay.

Initial participants include Saturn, Concrete and Cap, which CoinDesk reports have collectively processed more than US$100 million in volume.

PYUSDx tokens are issued by MoonPay Digital Assets and use PYUSD as their underlying backing asset.

Why it matters

The stablecoin market may increasingly consist of more than a handful of universal tokens.

Businesses could instead choose to issue branded or purpose-built digital currencies while relying on regulated stablecoins and third-party infrastructure underneath.

That creates a potentially different model for stablecoin adoption: the end user may interact with a business-specific digital currency while the underlying settlement infrastructure is provided by another stablecoin.

It also reinforces the growing importance of interoperability between different digital currencies.

🏦 Banking & Digital Money

Tokenised bank deposits move beyond traditional banking hours

Two developments in Singapore this week showed how quickly banks are progressing their tokenised-deposit experiments.

On 5 September, DBS and Citi completed the first successful weekend U.S. dollar payment between Singapore and the United States using tokenised deposits on Swift’s Digital Ledger.

DBS said the transaction took minutes, compared with an industry norm of up to two business days for conventional cross-border payments affected by banking hours, time zones and weekends.

Then on 10 September, DBS, OCBC and UOB completed live domestic Singapore-dollar transactions using tokenised deposits on the same Swift ledger, the first live interbank SGD transactions of their kind involving all three Singapore banks.

Why it matters

This is a genuine progression from the Swift transactions we covered previously.

The focus is moving from demonstrating that tokenised deposits can work to demonstrating when and where they can add value, particularly outside conventional banking hours and across institutional payment networks.

It also reinforces a theme we’ve been following closely:

Stablecoins and tokenised bank deposits are developing in parallel.

Both aim to make money more programmable and available across always-on financial infrastructure. The longer-term challenge will be enabling those different forms of digital money to interact efficiently.

📈 Institutional Markets

Bitcoin and Ether ETFs record a third consecutive week of inflows

U.S. spot Bitcoin ETFs recorded approximately US$987 million in net inflows for the week ended 4 September, extending their run of positive weekly flows to three consecutive weeks.

BlackRock’s IBIT accounted for approximately US$692 million of the weekly total.

U.S. spot Ether ETFs also recorded their third consecutive positive week, attracting approximately US$218 million.

For August as a whole, Bitcoin ETFs attracted approximately US$3.52 billion, while Ether ETFs recorded approximately US$1.85 billion in net inflows.

Why it matters

Weekly ETF flows can fluctuate significantly, so they shouldn’t be treated as a definitive measure of long-term institutional conviction.

What is notable is the continued use of regulated ETF structures as a channel through which investors can gain digital-asset exposure using familiar traditional-market infrastructure.

That bridge between conventional capital markets and digital assets continues to deepen.

🇦🇺 What does this look like in Australian dollars?

Many of this week’s developments centre on a simple problem: how do businesses move fiat-denominated value efficiently across digital financial infrastructure?

That same question applies to Australian dollars.

That’s where AUDX fits.
