Stablecoins are crypto’s killer app—but no one can agree on who will use them

Stablecoins are gaining regulatory clarity after the 2025 passing of the GENIUS Act, but the article highlights adoption friction—merchants worry about chargebacks and added complexity in payments. It cites Tether’s ~$183B stablecoin business as evidence of consumer use in developing markets, while North America adoption remains unclear. Airwallex is shifting from skepticism to a “last mile” model for converting U.S. stablecoins into local currency, supported by a Visa investment and a compliant blockchain initiative via its backing of Metal, though intense competition (e.g., Rain, MoonPay) and early-stage “agentic commerce” make outcomes uncertain.

Analysis

The investable value here is not in the token itself; it sits in the regulated conversion layer, treasury plumbing, and compliance stack. In the U.S., stablecoins are still fighting entrenched consumer habits, so the near-term economics are mostly B2B cross-border and balance-sheet efficiency rather than retail payments. That makes incumbents with licenses, liquidity, and merchant distribution more important than the issuers of the coin.

Competitive pressure is likely to be felt first by remittance and cross-border FX businesses that monetize spread, float, and fee opacity. The more stablecoins become a default settlement asset, the more that value migrates to on/off-ramp operators and away from legacy wire and money-transfer economics. Visa is interesting because it can either lose some settlement rents over time or capture them by owning the conversion/acceptance layer; the market is likely underestimating the optionality but overestimating the near-term revenue contribution.

Catalyst timing matters: over the next 1-3 months, the key signal is not press-release partnerships but actual throughput, corridor data, and disclosed conversion volumes. Over 6-18 months, the real risk is agentic commerce: if machine-to-machine payments scale, low-friction stablecoin rails could matter materially for microtransactions. The thesis is falsified if stablecoin activity does not show up in payment volumes or revenue disclosure across the next two earnings cycles, or if regulatory friction in non-U.S. corridors keeps adoption boxed into niche use cases.

Key Decisions for Investors

• No immediate broad long/short in the stablecoin theme: the signal is too early, so wait for verified transaction-volume disclosure or corridor expansion before adding risk.
• Small tactical long V on weakness over the next 1-3 months as a picks-and-shovels optionality trade; thesis is that V can monetize conversion and acceptance rather than be disintermediated. Cut if cross-border growth or fee mix deteriorates for two consecutive quarters.
• Watchlist short WU / legacy remittance processors over 6-12 months if stablecoin on/off-ramp volumes begin to show real adoption in high-friction corridors; this is a margin-compression story, not a volume-collapse story.
• Do not buy the 'agentic commerce' narrative outright yet; consider it only after a second data point from earnings or product disclosures confirms actual merchant or bot-driven throughput.
• Set an alert for any meaningful shift away from USD-backed dominance; if local-currency stablecoins scale faster than expected, the current winner set changes and the Visa optionality thesis weakens.
