The countdown to ultra-fast trading has begun. Cyprus financial regulators are forcing market participants into intensive preparation as the EU officially squeezes transaction settlement windows from two days down to just 24 hours ($T+1$). This operational rewrite leaves zero room for manual errors and forces immediate adaptation. Here is the fast-forward breakdown.

The Cyprus Securities and Exchange Commission (CySEC) has stepped up preparations for the European Union's transition to a T+1 securities settlement cycle, issuing new guidance aimed at ensuring regulated entities are ready for a significant operational change.

In Circular 780, published on Wednesday, the regulator outlined new regulatory requirements and supervisory expectations ahead of the shift to T+1 settlement, under which securities transactions must settle one business day after trade execution rather than the current two-day cycle.

The move follows amendments to the EU Central Securities Depositories Regulation (CSDR) through Regulation (EU) 2025/2075 and forms part of broader efforts to align European markets with international settlement standards already adopted in major jurisdictions.

CySEC said the shorter settlement cycle is expected to strengthen market resilience while reducing counterparty and operational risks. However, it warned that the transition will require extensive preparation across the trading and post-trading ecosystem.

The new requirements apply to a broad range of market participants, including central securities depositories, central counterparties, custodians, brokers, intermediaries, asset managers and investors involved in transactions covered by Article 5 of the CSDR.

Among the key challenges identified by the regulator are significantly compressed processing timelines, which will leave institutional investors, intermediaries and fund administrators with less time to allocate, confirm, match and settle trades.

CySEC also highlighted the growing importance of automation, noting that manual processing and operational inefficiencies could substantially increase settlement risks in a T+1 environment.

The regulator further warned that firms will need to manage liquidity, collateral and funding requirements earlier in the trade lifecycle to ensure the timely availability of cash and securities for settlement.

Cross-border transactions may also become more complex due to differences in time zones, foreign exchange execution schedules and pre-funding requirements, the Circular noted.

To assess the market's preparedness, CySEC is encouraging all affected regulated entities to participate in two industry surveys running in parallel until June 9.

The first survey, coordinated through national competent authorities and the European Securities and Markets Authority (ESMA), will provide regulators with supervisory insight into firms' readiness levels. Responses will be accessible only to CySEC and ESMA.

A second survey, conducted by the EU T+1 Industry Committee (EUIC), aims to gauge industry-wide preparedness across EU member states.

The questionnaires seek information on settlement performance, system and process readiness, third-party dependencies, testing plans and key implementation risks.

CySEC Chair Dr George Theochardies described the transition as a "significant operational change" that requires firms to review and adapt systems, controls and processes throughout the trading and post-trading chain.

"The new Circular refers to clear requirements for regulated entities to assess the impact on their activities sufficiently in advance to ensure a smooth and timely transition that enhances market resilience," Theochardies said.
