Banks didn’t suddenly fall in love with crypto. They fell in love with the deposits. And right now, they think the rulebook could cost them trillions and hand the future of money to their rivals.
Basel to Capitol Hill: Two Fronts, One Fight
Wall Street’s biggest trade groups are mounting a coordinated push to pause and rewrite impending crypto rules.
On one front, they want the Basel Committee’s crypto capital regime, finalised in 2022 and due to bite in January 2026, put on ice and “recalibrated.” On the other hand, they’re lobbying Congress to tighten the new GENIUS Act stablecoin law, which they say leaves loopholes big enough to drain deposits from banks.
The message is consistent: as written, the rules are “punitive” and risk locking regulated banks out of digital assets just as the market goes mainstream.
“Punitive” Means What, Exactly?
Basel’s framework gives the riskiest crypto exposures (so-called Group 2 assets, like unbacked tokens) an eye-watering 1,250% risk weight and caps total Group 2 holdings to roughly 1% of Tier 1 capital – guardrails that can make bank participation uneconomic.
That’s the point; prudential rules are built to survive bad days, not bull runs. But banks argue the calibration overshoots and pushes activity outside the perimeter.
In August, a coalition led by Global Financial Markets Association (GFMA), Institute of International Finance (IIF) and International Swaps and Derivatives Association (ISDA) asked Basel to “temporarily pause” implementation and redo the math with fresher data; the language echoed across financial press and member memos.
The New Fault Line: Stablecoins vs. Bank Deposits
Enter the GENIUS Act – Washington’s fledgling stablecoin rulebook. Banks say it bars issuers from paying interest directly, but still lets affiliates and platforms dangle yield-like rewards. That, they warn, turns stablecoins into a high-speed siphon from checking accounts. Their fix: close the interest “loophole,” curb non-bank issuers, and harden supervision.
The stakes are why this fight is loud: multiple reports say Treasury analysis pegs potential deposit outflows at up to $6.6 trillion if stablecoins can effectively offer yield. That number has raced through boardrooms and op-eds all summer, and it gets regulators’ attention. (Crypto advocates dispute the figure’s assumptions, arguing banks are protecting turf.)
America Just Flipped the Sign to “Pro-Crypto.” Now What?
Context matters: the U.S. has swung to a more permissive stance under President Trump, with regulators easing restrictions on banks’ involvement in digital assets.
Federal Reserve Vice Chair for Supervision Michelle Bowman captured the moment when she told Bloomberg TV that U.S. regulators are taking a “different look” at crypto, and argued Fed staff should be allowed small crypto holdings to understand it firsthand. She warned against an “overly cautious mindset”, a signal that, in practice, regulators need to learn fast and supervise smart.
What Banks Want (And Why It Matters)
1) Slow the Basel roll-out; recalibrate the capital stack.
Trade groups argue the 2022-era framework doesn’t reflect today’s market structure (tokenised cash, better custody, clearer disclosures). They want time to refine capital and disclosure templates so participation is viable inside the perimeter, not forced outside it.
2) Seal the GENIUS Act’s “yield” gap.
If platforms can route rewards through partners, banks say you’ve recreated an interest-bearing stablecoin in practice with fewer guardrails than deposits. Their letter asks Congress to extend the ban to affiliates and narrow who can issue.
3) Keep the playing field level, or credit tightens.
The industry’s macro case: a rapid shift from deposits into yieldy stablecoins could shrink banks’ funding base and chill lending. (Sceptics counter that market share will follow whoever builds the safest rails, bank or non-bank.)
The Counter-Case: Don’t Smother What Works
Crypto groups reply that stablecoins are already vacuuming up Treasury bills and could strengthen U.S. debt markets, and that banks shouldn’t get veto power over a technology they’ve been slow to adopt.
Some economists warn that the real trade-off is who supplies short-term dollar funding: banks via deposits, or stablecoin issuers via T-bill portfolios.
Either way, there are system-wide implications regulators can measure and manage.
The Rules Are Moving – With or Without Banks
Here’s the uncomfortable truth embedded in this summer’s letters and leaks: crypto is getting a rulebook either way.
If banks help write it, they’ll keep a central role in payments, custody and tokenised cash. If they don’t, the perimeter will grow around them, and the next generation of “deposit-like” money will be born in code, not branches.
$6.6 Trillion Reasons Not to Sit This Out
Regulators can tighten, soften, or delay, but they can’t ignore the scale of what’s at stake. Banks warn punitive rules will only push risk offshore. Crypto firms argue efficiency wins, no matter who supplies it.
Either way, the outcome will decide who gets custody of the next generation of money.
