Coinbase Defends Stablecoins, Rejects Claims They Undermine U.S. Banking System

Crypto powerhouse Coinbase is fiercely defending stablecoins against accusations they’re siphoning deposits from American banks, calling the “deposit erosion” myth a baseless ploy to shield banks’ $187 billion payment processing empire. In a October 29, 2025, market note, Chief Policy Officer Faryar Shirzad argued these dollar-pegged tokens enhance U.S. financial dominance abroad, not undermine it at home.

The pushback targets lobbying by five major U.S. bank trade groups urging tighter GENIUS Act rules—the July 2025 federal stablecoin framework signed by President Trump. Critics, including Citigroup analysts, warn yield-bearing stablecoins could spark a 1980s-style deposit flight, potentially draining $6.6 trillion per Treasury estimates, echoing money market fund booms that gutted bank lending. IMF’s 2025 report amplifies risks: shrinking deposits could crimp lending, while runs on issuers might trigger contagion, rivaling 2023’s Silvergate collapse.

Coinbase counters: Stablecoins, backed by cash and U.S. Treasuries held in regulated banks, aren’t savings substitutes but payment rails for DeFi and cross-border flows—two-thirds on-chain, per Shirzad. With U.S. bank deposits topping $18 trillion and stablecoin supply at $300 billion, overlap with community banks is “barely existent,” driven by international users dodging local currency woes. No correlation to deposit flight emerged in five-year data, Shirzad noted, urging banks to innovate rather than lobby.

USDC, Coinbase’s linchpin with Circle, boasts a $76.3 billion market cap as of October 30, 2025, fueling instant remittances, merchant payouts, and emerging-market access—up from $32.4 billion in March. Reserves, audited monthly, stay in FDIC-insured spots, recycling liquidity back into the system.

Amid Fed scrutiny and GENIUS Act tweaks for yields and master accounts, Coinbase champions federal clarity to outpace EU’s MiCA and UK’s frameworks. Bitwise’s Matt Hougan echoes: Banks

Stablecoins aren’t bank busters—they’re dollar extenders in a $300B ecosystem. As adoption surges, policymakers must harness innovation without stifling it. For stablecoin investors: Eye GENIUS updates, reserve audits, and global yields—America’s edge depends on smart regulation.
