EX.IO and Payment Asia Team Up to Build Hong Kong’s Licensed Stablecoin Infrastructure

Hong Kong‑based digital‑asset exchange EX.IO has signed a Memorandum of Understanding with payment‑services firm Payment Asia to create a full‑stack, regulated stablecoin ecosystem that bridges trading, custody, and merchant acquiring in the city’s nascent stablecoin market.

The partnership brings together two complementary capabilities. EX.IO, one of the first platforms licensed under Hong Kong’s Securities and Futures Commission (SFC) regime, contributes a “de‑risked” trading and custody layer built around strict AML/KYC controls. Payment Asia supplies a mature merchant‑acquiring network that already processes credit‑card, e‑wallet, and omni‑channel payments for SMEs and multinational corporations across Asia.

Together they will:

• Offer custodial services for licensed stablecoins on EX.IO’s exchange, enabling institutional investors and corporate treasuries to hold regulated digital assets alongside fiat balances.
• Integrate stablecoin settlement into Payment Asia’s acquiring stack, allowing merchants to accept stablecoins as a direct payment method and settle instantly in HKD or USD.
• Develop a subscription‑and‑trading front‑end that lets users buy stablecoins with fiat, trade them on EX.IO, and move the proceeds straight into a merchant’s payment gateway.

The memorandum does not lock the parties into a joint product launch; instead, it outlines a collaborative roadmap that will be refined as Hong Kong’s “deemed‑licensed” stablecoin framework matures.

Technology Stack and Use Cases

EX.IO’s platform already supports a full‑chain compliance suite: real‑time AML screening, on‑chain analytics, and cold‑storage custody that meets SFC requirements. By exposing its APIs to Payment Asia, the two firms can automate the following flows:

• Instant fiat‑to‑stablecoin conversion at the point of sale, reducing the friction that typically forces merchants to rely on third‑party exchanges.
• Cross‑border settlement for enterprises that need to move funds between Hong Kong and regional hubs without incurring FX spreads, leveraging the stablecoin’s 1:1 peg to USD.
• Tokenized loyalty programs, where a retailer can issue branded stablecoins that are redeemable both online and in physical stores, all settled on the same ledger.

These capabilities align with the broader “embedded finance” trend, where non‑bank entities embed regulated financial services directly into their products.

Competitive Landscape

Globally, firms such as Circle, Paxos, and Binance are racing to secure stablecoin licences in key jurisdictions. What sets the EX.IO‑Payment Asia alliance apart is its focus on regulated, on‑shore issuance paired with a merchant‑acquiring engine that already serves millions of transactions in Asia. Most competing solutions rely on third‑party payment processors or operate in a “sandbox” environment, which can delay real‑world adoption.

In the U.S., the Federal Reserve’s Project Centric is still in the proof‑of‑concept stage, while Europe’s Euro‑stablecoin pilots are limited to institutional corridors. Hong Kong’s recent issuance of two stablecoin licences by the HKMA gives the EX.IO‑Payment Asia combo a first‑mover advantage in a market projected by McKinsey to reach US$16 billion in transaction volume by 2027.

Implications for Enterprise Marketing

For B2B marketers, the announcement signals a shift from “digital‑currency awareness” to actionable integration. Companies that previously promoted generic crypto‑acceptance can now position stablecoins as a compliant, low‑volatility payment option, backed by a regulated exchange and a local acquiring partner. Marketing teams will need to:

• Highlight risk mitigation (regulatory licensing, AML compliance) in messaging to CFOs and treasury leaders.
• Showcase speed and cost benefits—instant settlement versus traditional wire transfers that can take days and incur high fees.
• Build case studies around cross‑border supply‑chain finance, where stablecoins reduce currency exposure for Asian manufacturers.

The partnership also opens doors for co‑branded campaigns, such as joint webinars on “stablecoin‑enabled commerce” or API‑sandbox hackathons that invite fintech developers to prototype new merchant use cases.

Market Landscape

Hong Kong’s stablecoin regulatory framework reached a critical inflection point on April 10, when the HKMA granted the city’s first two stablecoin licences. The move follows a broader global trend: Gartner predicts that 70 % of banks will embed stablecoin services into their digital channels by 2025, and IDC estimates that regulated digital‑asset infrastructure will account for 15 % of total fintech spend in the Asia‑Pacific region over the next three years.

The city’s “One‑Stop Stablecoin Hub” strategy aims to attract issuers, exchanges, and payment providers into a tightly regulated ecosystem. By pairing a licensed exchange with a seasoned acquirer, EX.IO and Payment Asia are effectively building the “last mile” of that vision—turning tokenized fiat into a usable payment method for merchants and consumers alike.

Top Insights

• Regulated infrastructure wins: The combination of SFC‑licensed exchange custody and Payment Asia’s acquiring network gives the partnership a compliance edge over global peers still in sandbox phases.
• Enterprise adoption accelerates: Instant fiat‑to‑stablecoin conversion at checkout removes a major barrier for corporate treasuries seeking low‑volatility digital assets.
• Competitive moat: While Circle and Paxos focus on global liquidity, EX.IO‑Payment Asia target the localized Hong Kong market, leveraging the HKMA’s new licences for a first‑mover advantage.
• Marketing shift: B2B marketers can now position stablecoins as a risk‑managed, cost‑effective payment rail rather than a speculative asset.
• Market size outlook: McKinsey projects Hong Kong’s licensed stablecoin transaction volume to hit US$16 billion within two years, underscoring the commercial potential for early adopters.
