What Happens When Every Bank, Fintech and Payments Company Launches Its Own Stablecoin?

Regulation is making stablecoin issuance possible. The next challenge is determining which stablecoin ecosystems become economically competitive. 

For years, the stablecoin industry has been focused on one objective: creating a regulatory framework that allows mainstream financial institutions to issue digital dollars with confidence.

That future is beginning to arrive. According to Visa Onchain Analytics, stablecoins have processed more than $51 trillion in transaction volume over the past 12 months, while global circulating supply now exceeds $270 billion, demonstrating how liquidity has naturally concentrated around a handful of dominant ecosystems. , while the market continues to expand rapidly beyond crypto-native use cases into payments, treasury, lending and savings. The question is no longer whether demand exists. It is how the next generation of regulated issuers compete. 

The United States has established a federal framework for payment stablecoins through the GENIUS Act. Europe has implemented MiCA, creating a regulated market for electronic money tokens. Across Asia, regulators continue developing their own approaches as banks, payment providers and financial institutions accelerate investment in tokenised deposits, stablecoins and blockchain-based settlement.

The debate is no longer whether banks, fintechs and payment providers will launch stablecoins. It is what happens when they all do. For much of the last decade, stablecoins competed on issuance, accessibility and adoption. Success depended on regulatory clarity, exchange listings and network effects.

Today, USDT, USDC and USDS account for almost 85% of total stablecoin supply (DefiLlama), allowing capital to naturally concentrate around a handful of dominant ecosystems. That concentration has served the market well. However, as GENIUS, MiCA and other regulatory frameworks enable hundreds of new issuers to enter the market, liquidity will inevitably become fragmented across individual ecosystems.

As regulatory barriers fall, issuing a stablecoin increasingly becomes the cost of entry rather than the source of competitive advantage. The next phase of competition will no longer be determined by who creates another digital dollar, but by who creates the greatest financial utility around it. 

That transition is already underway. PayPal continues expanding products around PYUSD. Robinhood is building the USDG ecosystem through the Global Dollar Network. Coinbase is 

extending financial services around USDC. Stripe’s acquisition of Bridge, Deel’s investment in stablecoin-powered payments and growing activity from banks across the US, Europe and Asia all point in the same direction.

Stablecoins are evolving from digital assets into financial operating systems.

The Next Challenge Isn’t Issuance

Citi estimates the market could generate more than $58 billion in annual revenue by 2030. Regulation is enabling the market to scale, but scale alone will not determine the winners.  Every institution can, and appears to be, building a regulated stablecoin. The harder challenge is making that stablecoin economically useful supporting:

• Savings products that require predictable yield.
• Payments requiring deep liquidity.
• Lending which requires efficient capital deployment.
• Treasury products require resilient risk management.

Each additional financial product competes for the same pool of capital. As ecosystems expand, institutions must continuously balance liquidity, yield generation, redemption performance and risk without compromising the customer experience. The institutions that succeed will not simply issue regulated stablecoins. They will build financial operating models capable of allocating capital intelligently across multiple financial products, ensuring that every dollar works harder while maintaining liquidity, resilience and sustainable returns.

In other words, the competitive advantage is shifting from just issuing stablecoins to intelligently coordinating how capital is deployed making it accessible, once those stablecoins exist. 

Allocation Intelligence Becomes the Competitive Advantage

This creates an entirely new layer within financial markets. As stablecoin ecosystems become more sophisticated, competitive advantage increasingly shifts from issuing digital dollars to intelligently coordinating the capital behind them.Rather than competing to issue another stablecoin, specialist financial operating models are emerging to help institutions maximise the productivity of the capital already inside their ecosystems. 

Unlike traditional asset managers, where investment decisions are made by portfolio managers, Spark operates within a transparent, rule based framework where the parameters governing capital deployment are approved before capital is allocated. Within those parameters, Spark’s allocation intelligence coordinates capital across regulated issuers, custody providers, lending markets and liquidity venues. The rules governing how capital can be deployed are defined in advance. Within those predefined parameters, Spark’s allocation intelligence coordinates capital across approved strategies while leveraging the capabilities of specialist infrastructure providers responsible for custody, settlement, lending and liquidity. 

In practice, this means continuously balancing liquidity, capital efficiency, redemption performance, yield generation and institutional risk as market conditions evolve, rather than relying on static allocation models or a single source of yield. This is fundamentally different from maximising headline APY. It is about maximising the long-term productivity of capital while ensuring financial products remain liquid, resilient and commercially sustainable. The institutions that consistently deliver returns aligned to benchmark rates such as SOFR, while maintaining predictable liquidity and near-instant redemptions at scale, will be best positioned to earn long-term institutional trust.

Over time, the institutions that attract the most users may not be those with the largest balance sheets or the most recognised brands. Competitive advantage is likely to come from building financial operating models capable of coordinating capital across an increasingly connected financial ecosystem. 

Why Banks Won’t Build This Themselves

A bank can build a stablecoin. It can build a lending market. It can integrate with a custodian. What is much harder is building a financial operating model capable of coordinating capital across multiple independent infrastructure providers while maintaining liquidity, risk and capital efficiency at scale.

The individual building blocks already exist. Lending markets provide credit. Custody providers safeguard assets. Liquidity venues facilitate trading. RWA platforms expand the range of available financial products. The challenge is no longer building each component in isolation. It is coordinating capital intelligently across them as a single financial system.

Traditional financial markets solved this problem decades ago. Banks do not build proprietary foreign exchange markets every time they introduce a new currency or payment product. They connect to shared financial infrastructure that enables capital to move efficiently between participants while maintaining deep liquidity.

Stablecoin markets are beginning to face the same challenge. As regulated issuers multiply, liquidity cannot remain isolated within individual ecosystems. Capital needs to move efficiently between savings, lending, payments and treasury applications, and increasingly between stablecoin ecosystems themselves.

Spark’s recently launched Stablecoin FX Layer, built on Uniswap, represents one example of how this market is beginning to evolve. Rather than requiring every new issuer to recreate liquidity from scratch, it enables regulated stablecoin ecosystems to access deeper shared liquidity while increasing the financial utility of the capital already within those ecosystems.

As regulated stablecoin ecosystems proliferate, they will increasingly require similar financial coordination. Capital cannot remain isolated within individual issuers if institutions expect stablecoins to support global payments, lending, treasury and savings products at scale. The next stage of market evolution is therefore unlikely to be another stablecoin launch. It is the development of deeper liquidity between stablecoin ecosystems, allowing capital to move wherever it can create the greatest financial utility.

This is ultimately where Spark’s role sits. Rather than replacing existing infrastructure providers, Spark applies allocation intelligence across an established network of lending markets, liquidity venues and financial infrastructure within predefined governance and risk parameters. As the number of stablecoin issuers grows, that coordination layer becomes increasingly important, allowing institutions to launch new financial products without having to bootstrap their own liquidity network and financial infrastructure from scratch. 

The Next Generation of Financial Infrastructure

Specialist providers are already beginning to build for this future. Rather than replacing regulated issuers, custody providers, lending markets or exchanges, the next generation of financial operating models will integrate with existing market infrastructure while intelligently coordinating how capital is deployed across it. 

Spark’s recently announced Stablecoin FX Layer, built on Uniswap, represents one example of how the market is beginning to evolve. Rather than treating stablecoins as isolated pools of liquidity, it explores how regulated stablecoin ecosystems can access deeper, more capital-efficient liquidity while increasing the financial utility of the capital behind them. 

The same operating model can support ecosystems built around PayPal’s PYUSD, Robinhood’s USDG, Circle’s USDC and Tether’s USDT, alongside the growing number of regulated stablecoins expected to emerge from banks, fintechs and payment providers. 

As these ecosystems expand, allocation intelligence becomes increasingly important—not simply to coordinate capital across financial products, but to enable new stablecoin ecosystems to access deeper shared liquidity and financial utility from day one. Rather than rebuilding liquidity market by market, capital can be allocated more efficiently across governance-approved opportunities, improving market accessibility while reducing the capital fragmentation that naturally emerges as new issuers enter the market. 

Traditional financial markets do not expect every bank to build its own foreign exchange market from scratch. Instead, institutions access shared liquidity that allows capital to move efficiently between currencies while maintaining deep, liquid markets. As regulated stablecoin ecosystems proliferate, similar financial models are likely to emerge. Spark’s Stablecoin FX Layer represents one early example of this evolution, demonstrating how shared liquidity can help new stablecoin ecosystems access deeper shared liquidity, improve capital efficiency and accelerate ecosystem growth without recreating the entire liquidity stack from scratch. 

Regulation Creates the Next Challenge 

GENIUS, MiCA and similar regulatory frameworks represent an important milestone. They create the legal foundations for banks, fintechs and payment providers to issue regulated stablecoins at scale. Regulation, however, does not determine which ecosystems ultimately succeed. It changes the basis of competition. 

In Europe, MiCA has effectively brought compliant fiat-backed stablecoins into a regulated electronic money framework. As the next phase of the regulation comes into effect on 1 July 2026, many of the operational compliance requirements increasingly fall on exchanges, custodians and other access points, accelerating the transition towards regulated stablecoin ecosystems while prompting many European exchanges to phase out support for non-compliant assets such as USDT.

The result is likely to be a market with significantly more regulated issuers than ever before. Banks, fintechs and payment providers will increasingly be able to launch proprietary stablecoins with greater regulatory certainty. That is a positive step for the industry, but it also creates a new challenge: liquidity, capital and financial utility become increasingly fragmented across a growing number of ecosystems.

Spark’s recently announced Stablecoin FX Layer represents one example of how the industry is beginning to address that challenge. . Rather than requiring every new issuer to bootstrap deep  liquidity and financial infrastructure from scratch. Shared liquidity models can help new ecosystems access deeper markets, improve capital efficiency and accelerate adoption from day one.

Robinhood’s USDG launch is therefore more than another crypto earn product. It is an early indication of where financial markets are heading. Regulation is making stablecoin issuance accessible to a growing number of institutions. The next phase of competition will be defined by the financial operating models that connect those ecosystems, coordinate capital efficiently and maximise the financial utility of the assets behind them. The next winners may not be the institutions that issue the next stablecoin. They are likely to be those that make every stablecoin more useful.
