FINRA's new intraday margin framework took effect on 4 June 2026, retiring the old pattern-day-trader rule and replacing the $25,000 minimum with real-time margin monitoring that can trigger a 90-day freeze after repeated deficits. The hook for active US retail traders is simple: the rule that protected them from the PDT designation for years no longer exists.
The Financial Industry Regulatory Authority amended Rule 4210 in 2025 and the SEC approved the change on 14 April 2026. The new framework requires broker-dealers to monitor intraday margin deficits — the largest shortfall between a customer's equity and the maintenance margin requirement after any transaction that reduces the intraday margin level. If a customer fails to satisfy such a deficit by the fifth business day, and does so as a practice, the firm must impose a 90-calendar-day freeze on creating or increasing short positions or debit balances.
The phase-in runs through 20 October 2027. Some brokers adopted the new model in early June 2026, others are still transitioning. That staggered rollout matters: two clients of different firms can face different timelines for the same deficit.
The new rule does not change the $2,000 minimum to open a margin account. That figure still applies. What was removed was the $25,000 day-trading minimum, and the confusion between the two is widespread in late-2026 retail commentary. The $25,000 was the previous day-trading cap; it is no longer in effect. The $2,000 is the long-standing minimum to open any margin account, and it still applies. Anyone treating them as interchangeable is making a category error.
The practical effect is that small accounts can now day-trade legally, but the broker's monitoring software will catch margin deficits in real time. Some firms issue real-time alerts and prevent the next trade from placing the account in deficit. Others calculate at end-of-day and issue the call the following morning. The faster approach is safer for the trader; the slower one is more permissive but more punitive.
The rule includes a small-deficit exemption: the lesser of 5% of account equity or $1,000. A trader whose equity is $20,000 can have a $1,000 deficit without triggering the freeze. Deficits arising from extraordinary circumstances — extreme volatility, corporate actions, system outages — are also exempt at the firm's discretion. Beyond those tolerances, repeated deficits build toward the freeze.
This means a trader who runs an account near the maintenance margin edge on most days faces a structural risk that did not exist under the old rule. The old $25,000 floor was a hard barrier; the new model is a behavioural one. It punishes patterns, not single events.
The intraday margin overhaul applies to US equities and options margin accounts. Forex, futures and crypto margin at CFTC-registered brokers were never covered by the pattern-day-trader rule. Those products still operate under their own regulatory frameworks — CFTC retail forex leverage capped at 50:1 on major pairs, NFA requirements on forex dealer members, and SEC/CFTC joint rules for security futures. The 2026 FINRA change does not touch those products directly.
That said, brokers that offer both equities and CFDs may apply the intraday monitoring framework to the entire account, depending on their internal risk policy. US traders holding both an equity margin account and a forex account at the same broker should ask specifically how the firm aggregates activity.

Three questions are worth writing down before the next margin call:
The answers determine whether a trader's behaviour in one product can trigger a freeze in another.

Checked September 2026. The phase-in runs through October 2027; firms at different stages may apply the rule differently. Equity, futures and forex margin adjustments are separate regulatory frameworks, but broker-level aggregation can affect traders holding multiple products.
