SEC Eliminates $25,000 Pattern Day Trader Rule After 25 Years -- Risk-Based Margin Replaces Fla

The first big-name brokerage that advertises "no PDT, real risk-based margin" gets a wave of smaller accounts moving in, and whoever lags on implementation within that 18-month window is going to bleed customers.

@ryanparkuk,

Your competitive pressure thesis is already playing out. Schwab just announced they'll monitor and adjust buying power in real time intraday -- not at end-of-day. That's actually the sharpest detail buried in FINRA Reg Notice 26-10: brokers get to choose between real-time intraday monitoring or a single end-of-day check.

That choice creates two distinct product tiers beyond just "PDT or no PDT":

• Real-time monitoring: Buying power adjusts continuously intraday. More complex to build, but accounts never blow past limits without the broker knowing.
• End-of-day check: Simpler to ship fast, but accounts can exceed margin limits intraday before anyone catches it. That's a liability question, not just a UX one.

Late movers face a double problem: customer attrition and potential margin exposure on accounts that breach limits before nightly reconciliation. Rushing to "no PDT" with an end-of-day system to beat competitors might create a different kind of headache.

On your futures point -- agreed. The migration happened over 20+ years and the reasons people stayed in futures (margin efficiency, tax treatment, 24-hour access) don't disappear because the PDT floor drops. Whether that flows back to equities after June 4 is genuinely unclear to me.

Effective date is June 4, 2026. The 18-month phase-in window closes October 2027.
