US regulators dumped long-standing penny limits on share buying and selling costs and minimize the charges exchanges can cost their customers in new fairness market guidelines that nonetheless ended far wanting extra radical preliminary plans.
Wednesday’s adjustments are the second piece of a broader four-part shake-up of US inventory buying and selling first proposed in December 2022 by the Securities and Exchange Commission. Mixed, the plans symbolize the most important adjustments to the inventory market’s construction in 20 years. They’ve been one key factor within the formidable reform agenda pursued by SEC chair Gary Gensler.
The SEC’s 5 commissioners voted unanimously to cut back the so-called “tick dimension”, or unfold, between purchase and promote costs to a half-cent from a full penny for shares that met sure liquidity standards. The watchdog additionally slashed the entry charges that customers pay exchanges by two-thirds.
The hole between purchase and promote costs will cut back buying and selling prices for buyers however probably harm brokers together with large banks and high-frequency buying and selling corporations, which might revenue from these gaps. Nevertheless, any hit for market-makers would at the very least be partially offset by the massive minimize in entry charges additionally launched on Wednesday.
The foundations, which can take impact in November 2025, are designed to assist degree the enjoying subject between exchanges and different extra lightly-regulated “darkish swimming pools” which have boomed with the expansion of digital buying and selling. On the assembly, Gensler mentioned the new rules would “assist promote larger transparency, competitors, equity and effectivity in our $5tn fairness markets”.
The moderation within the ultimate guidelines marks the most recent climbdown by the SEC from preliminary plans following pushback by trade members. Others which have been softened from extra formidable beginnings embody new local weather knowledge reporting necessities for firms, increasing the definition of a seller within the Treasury market, and the extent of short-selling disclosures.

Tick dimension started to slim within the US inventory market within the late Nineteen Nineties. Initially priced in one-eighths of a greenback, they have been lowered to a penny in 2000 as fairness markets switched to decimal-based pricing, which till Wednesday additionally served because the minimal unfold allowed.
Initially the SEC had proposed a four-tier system that might have lowered spreads of some shares to tenths of a penny. However a broad coalition of trade members warned it risked decreasing liquidity by slicing costs too finely.
Requested after the assembly whether or not he anticipated authorized challenges on Wednesday’s rule adjustments, Gensler mentioned he was “fairly assured that is throughout the legislation and the way the courts interpret the legislation”.
Wednesday’s resolution to cut back tick sizes will most likely have the most important affect in buying and selling of extremely liquid shares the place there’s sufficient quantity to cost shares in fractions of a penny. Underneath the brand new guidelines, SEC employees estimate some 1,700 securities would have certified final 12 months for the brand new narrower buying and selling band, representing 43 per cent of all buying and selling by worth.
Entry charges are what brokers pay exchanges to acquire the quotes they submit. Exchanges in flip rebate a portion of charges relying on how actively a dealer locations purchase and promote orders — a system requiring common advanced updates to merchants’ software program programs. The distinction between the payment and the rebate is income for an alternate.
The SEC on Wednesday additionally mandated that exchanges should make commerce pricing, together with all charges and rebates, clear earlier than buying and selling — which means these have to be based mostly on earlier buying and selling volumes, not based mostly on month-end assessments as is finished now. SEC employees mentioned the adjustments would enhance transparency round buying and selling prices.
