Global Financial Giants Enter Stablecoin Arena in Pivotal Shift

The stablecoin landscape has evolved from early experimentation (2020-2022) and exploration (2023-2024) to full-scale acceleration in 2025. The sector's growth has surpassed all expectations: annual stablecoin transfer volume skyrocketed from a mere $3.3 billion in 2018 to $18.4 trillion in 2024, now exceeding the payment processing volumes of both Visa ($15.7 trillion) and Mastercard ($9.8 trillion).

Several landmark developments over the past month have brought this narrative to the forefront:

- Citi partnered with Coinbase to expand digital asset payment capabilities for institutional clients

- Nine European banks formed a consortium to launch a euro-denominated stablecoin by 2026

- Western Union announced plans to issue USDPT, a dollar stablecoin on Solana, with Anchorage Digital Bank handling issuance and custody

- Visa expanded stablecoin settlement support to four additional blockchain networks

- Mastercard is reportedly acquiring crypto infrastructure firm Zero Hash for $1.5-2 billion, following earlier competitive bidding with Coinbase for BVNK

These developments collectively signal a clear trend: traditional financial institutions are aggressively transitioning their core operations—from payment networks to cross-border settlements—toward programmable on-chain systems.

Banks: Stablecoins vs. Tokenized Deposits

As traditional banks embrace digital assets, they face two distinct paths. Initially, Citi CEO Jane Fraser expressed preference for tokenized deposits over stablecoins, citing regulatory comfort and seamless integration with existing banking infrastructure.

However, banks recognize that engaging with the crypto ecosystem requires stablecoin adoption. Citi's dual approach—exploring tokenized deposits while partnering with Coinbase—demonstrates strategic positioning to remain central to the future financial landscape, regardless of whether it evolves on public chains or traditional banking systems.

In Europe, nine major banks are advancing a euro stablecoin project under MiCA regulations, aiming to establish a European digital payment rail and counter dollar stablecoin dominance.

Western Union: Bridging Digital and Cash Economies 

The remittance giant is leveraging its extensive physical network to create a closed-loop system connecting digital wallets, stablecoin transfers, and cash payout locations. By partnering with Anchorage Digital Bank and building on Solana, Western Union aims to address core user needs: instant settlement, local cash accessibility, and reduced fees.

Card Networks: Connectors vs. Acquirers 

Visa and Mastercard are pursuing divergent strategies:

- Visa is evolving into a "multi-chain settlement router," expanding stablecoin settlement across four new chains and 25+ fiat currencies

- Mastercard is taking an acquisition-driven approach, moving to acquire Zero Hash and previously competing for BVNK to rapidly internalize crypto infrastructure capabilities

Persisting Challenges  

Despite accelerated adoption, significant hurdles remain:

1. Monetary Sovereignty Concerns: Global dollar stablecoin expansion raises digital dollarization fears, prompting regional responses like Europe's bank-led stablecoin initiative

2. Operational Resilience: Issuers must maintain stability during redemption surges, liquidity crises, and technical attacks while ensuring transparent reserve management

3. Regulatory Compliance： Cash-heavy models like Western Union's require navigating complex AML, forex, and multi-jurisdictional licensing requirements

The complexity of compliance and operational management now far exceeds technical integration challenges, explaining why major players are pursuing partnerships and acquisitions rather than solo ventures.

Conclusion

The recent wave of developments represents not a crypto victory but a quiet revolution in financial infrastructure. As "account + stablecoin" hybrid architectures become mainstream, users will experience faster settlement, lower costs, and enhanced stability without noticing the underlying technology. The competitive landscape will increasingly hinge on familiar financial metrics: network scale, fee structures, merchant adoption, and compliance execution—explaining why traditional finance has moved from observation to full participation in Q4 2025.
