Visa‑Mastercard‑Stripe‑Coinbase Launch OUSD Stablecoin Amid U.S. Crypto Custody Rule Proposal and Bitcoin ETF Outflows

This week, a high‑profile consortium of payments giants unveiled a groundbreaking stablecoin initiative, just as U.S. regulators rolled out a new proposal targeting crypto custody rules. At the same time, Bitcoin spot ETFs experienced notable net outflows, adding pressure to the broader digital‑asset market.

Payments Titans Launch Open USD Stablecoin

On September 30, Visa, Mastercard, Stripe, Coinbase, and Shopify jointly launched a new dollar‑pegged stablecoin called Open USD (OUSD). At launch, it was backed by approximately $1 billion in pledged liquidity and registered over $400 million in trading on day one, underscoring significant institutional commitment and market demand.

The collaboration marks one of the most significant efforts yet by traditional financial firms to enter the crypto space with fully backed digital currency infrastructure—a move that could accelerate mainstream stablecoin adoption and usage.

U.S. SEC Proposes Crypto Custody Framework

Also this week, the U.S. Securities and Exchange Commission proposed a new regulatory framework to modernize how investment advisers and funds handle crypto custody. The proposal would allow state trust companies to serve as custodians and introduce conditional self‑custody arrangements, subject to enhanced compliance and governance requirements.

This initiative represents a major regulatory step toward clarifying legal structures around custody of digital assets—impacting how institutional investors and advisors manage client crypto holdings under compliance regimes.

Spot Bitcoin ETFs See Net Outflows Amid Market Pressure

Meanwhile, U.S. spot Bitcoin ETFs experienced net redemptions. According to data for the week ending October 4, cumulative inflows into all U.S. spot BTC ETFs stood at approximately $57.6 billion in assets under management, but fund flows for the week slowed to $241 million—down from $2.39 billion the prior week. One ETF, IBIT, added $450 million while another, FBTC, saw $168 million withdrawn.

The slowdown in inflows reflects shifting investor sentiment despite Bitcoin posting a 2.4 % gain across the same week. These dynamics underscore the fragile nature of ETF‑driven demand in crypto markets.

Why These Developments Matter

The launch of OUSD by major payment firms could significantly expand stablecoin infrastructure by tying it to established financial networks and liquidity providers. If OUSD gains traction, it could reshape stablecoin usage patterns and integration with traditional payments.

At the same time, the SEC’s proposed custody framework offers much‑needed clarity for institutions navigating crypto asset safekeeping. By outlining permissible custody models and compliance protocols, the SEC may encourage broader institutional participation—once the rules are finalized.

Yet the tempered performance of Bitcoin ETFs this week—despite overall rising volumes—signals investor caution and the sensitivity of crypto markets to macroeconomic shifts, liquidity conditions, and regulatory developments.

Looking Ahead

Investors and industry participants will watch for the evolution of the SEC’s custody rulemaking, including public comment feedback and any revisions before finalization. Meanwhile, uptake of OUSD and its integration into merchant and financial platforms will be closely monitored.

Finally, ETF flows and performance will remain key indicators of institutional sentiment, especially in response to evolving regulation and macroeconomic conditions. In crypto’s current environment, regulatory clarity and institutional trust are vital for sustained growth.
