When the US and Canadian markets slashed their settlement window to just one day, the change promised faster trade finality and reduced counterparty risk.

But for financial firms across Europe and Asia, it has triggered a logistical scramble, compressing timelines, inflating costs, and straining cross-border trade operations like never before.

T+1: A Reform Born in Crisis

This is according to research by Vermiculus and GreySpark Partners, which pointed out that the transition set off a chain reaction for global firms with exposure to American markets.

The idea of moving to T+1 settlement started in 2020 and 2021. Market volatility during the COVID-19 pandemic and the meme stock mania exposed the fragility of a two-day settlement system. U.S. regulators pushed for a faster cycle to limit risk.

While North America, Argentina, and India now operate on a T+1 basis, most of the world—including the EU, UK, Singapore, and Hong Kong—still adheres to a T+2 cycle. This divergence means that firms operating across borders must now reconcile vastly different trade deadlines.

Allocating and affirming trades by 21:00 ET on the trade date is now mandatory. That creates a serious overlap problem for firms in Europe and Asia, where business hours end before U.S. markets close. European firms now have just three working hours to process trades, compared to ten under the previous regime.

Europe’s Compressed Clock

For UK and EU firms trading in U.S. markets, the time available to finalize trades has been cut nearly in half. This shift forces firms to either stretch working hours into the night or reconfigure operations to include global teams. Smaller firms without international coverage face higher risks of settlement failure—and heavier costs to avoid it.

In Asia, time zones prove even more unforgiving. Japanese firms, for instance, must now process U.S. trades after local business hours. The working-hour overlap is nonexistent. Without night shifts or relocated operations, these firms risk missing settlement deadlines altogether.

The FX dimension adds to the stress. Many APAC institutions are being forced to pre-fund trades or outsource foreign exchange processes due to tight timeframes and unfavorable conversion rates.

Nasdaq and the Intercontinental Exchange are betting on even longer trading hours. Nasdaq plans to roll out a 24/5 schedule by late 2026, targeting global investors used to the always-on crypto markets.

Toward Real-Time Trading?

Digital asset markets offer real-time settlement and 24/7 trading—features that traditional markets are slowly inching toward. The U.S. T+1 rule may be a step in that direction.

The EU and UK plan to shift to T+1 by October 2027. However, their fragmented market structures mean their transition may prove even more complex. In the meantime, global firms must consider whether to build costly night operations or embrace automation to survive the faster pace set by North America.
