Stablecoin Architecture 2026: Which Reserve Model Wins?

Frequently Asked Questions

01.Why did algorithmic stablecoins fail as an institutional-grade asset class?

Algorithmic stablecoins rely on reflexive token mechanisms rather than external collateral. The May 2022 TerraUSD collapse destroyed tens of billions in market value within 72 hours because the mint-burn arbitrage mechanism amplified the depeg rather than dampening it. Institutions require segregated, auditable reserves that cannot experience a self-reinforcing death spiral, which algorithmic designs structurally cannot provide under stress.

02.What does the GENIUS Act require from payment stablecoin issuers?

Signed into law on July 18, 2025, the GENIUS Act mandates 100 percent reserve backing with liquid assets, specifically US dollars or short-term Treasury securities. Issuers must publish monthly public disclosures of reserve composition. This framework effectively disqualifies pure algorithmic designs from the US payment stablecoin category and creates a regulatory floor that favours fiat-backed and RWA-backed issuers with verifiable custody arrangements.

03.How are BlackRock and Franklin Templeton validating the RWA-backed stablecoin model?

BlackRock BUIDL reached 3 billion USD in AUM by May 2026 (CoinDesk, June 2026) and became eligible as off-exchange collateral at major trading venues, enabling institutional counterparties to post it in lieu of cash for margin purposes. Franklin Templeton BENJI expanded to eight blockchains in the same period, including UCITS structures for European allocators. These products set the operational benchmark for institutional-grade stablecoin infrastructure in 2026.
