How Stablecoin Adoption Could Disrupt Traditional Payment Processors: Insights from Mizuho’s Dan Dolev

As the financial world moves rapidly toward digitization, a new wave of disruption is on the horizon: stablecoins. According to Dan Dolev, senior fintech equity research analyst at Mizuho, the adoption of stablecoins has the potential to significantly shake up the legacy payment ecosystem — posing both risks and opportunities for companies like Visa, Mastercard, and PayPal.
What Are Stablecoins?
Stablecoins are a type of cryptocurrency designed to maintain a stable value by being pegged to a reserve asset, such as the US dollar. Unlike volatile cryptocurrencies like Bitcoin or Ethereum, stablecoins aim to combine the speed and decentralization of blockchain with the price stability of fiat currencies.
Popular examples include:

USDC (USD Coin)
USDT (Tether)
DAI (Decentralized stablecoin)

These digital assets are increasingly used for remittances, e-commerce, and peer-to-peer transactions.
Why Stablecoins Matter in the Payments World
Dan Dolev believes that stablecoins are not just a technological fad, but a legitimate threat to the traditional business models of payment processors. Here’s why:
1. Lower Transaction Fees
Traditional payment rails (credit cards, debit cards, ACH) typically involve fees for every transaction — often passed along to merchants or users. Stablecoins can significantly reduce transaction costs thanks to their blockchain architecture, particularly on Layer 2 networks like Polygon, Solana, or Ethereum rollups.

“If stablecoins become widely adopted, the fundamental economics of card processors could be severely impacted,” says Dolev.

2. Instant Settlement
Unlike conventional banking systems that require days to settle transactions, stablecoin payments can be settled within seconds, even across international borders. This offers a major efficiency boost, especially for cross-border payments, which are traditionally slow and expensive.
3. Bypassing Banks and Intermediaries
Stablecoins enable peer-to-peer payments without intermediaries. This can remove layers of friction in traditional systems where banks, payment gateways, and clearing houses all take a cut. A more streamlined payment flow would reduce reliance on companies like Square, Stripe, or Visa.

The Potential Winners and Losers
✅ Winners:

Crypto Wallet Providers like MetaMask and Phantom
Blockchain Networks powering stablecoin transactions (Solana, Ethereum, Avalanche)
Fintech startups integrating stablecoins for faster global payments

❌ Losers:

Traditional payment giants like Visa, Mastercard, and PayPal
Banks relying on high fees from wire transfers and ACH transactions
Legacy processors that fail to pivot to blockchain-based systems


Regulators Are Watching
The rise of stablecoins has also drawn attention from global regulators. Questions around consumer protection, anti-money laundering (AML), and financial stability are being debated. The U.S. Treasury and SEC are already considering new frameworks to oversee stablecoin issuers, which could influence how quickly they’re adopted at scale.

What’s Next?
Dolev suggests that we are only in the early innings of stablecoin adoption. While they’re currently more common in crypto-native ecosystems, the next wave will involve integrations into mainstream apps and services. Already, companies like PayPal have launched their own stablecoin (PYUSD), a clear signal that traditional players see the writing on the wall.
Final Thoughts
Stablecoins are more than just a crypto curiosity — they’re a fast, cheap, and efficient alternative to the outdated systems of legacy payment processors. Analysts like Dan Dolev at Mizuho are sounding the alarm early: adapt or risk obsolescence.
For consumers, stablecoins represent freedom and efficiency. For incumbents, they may represent disruption and transformation. One thing is clear: the payments landscape is about to change — possibly forever.
