What the Settlement Window Was Actually For
The settlement window serves critical operational functions like netting and risk management, which are not simply removed by faster settlement cycles.Summary
The article argues that the reduction of settlement cycles from T+2 to T+1 and the move toward T+0 is often misunderstood as merely a quest for speed. The author contends that the time between trade and settlement is a necessary working window that supports essential post-trade functions such as netting, fails management, and liquidity management. Compressing this window does not eliminate these functions but rather pulls them forward and concentrates them into a tighter timeframe, creating a significant technological challenge. The article further notes that the impact of settlement compression is uneven across different market participants and that true atomic settlement at T+0 fundamentally changes the economics by removing the liquidity benefits of netting. Consequently, the author suggests that a selective approach, where most activity settles on a fast but netted cycle while high-value trades settle atomically, is likely to be the durable design rather than a universal shift to instant settlement. Finally, the article concludes that modernizing post-trade technology requires redesigning these processes rather than simply running them faster, as the existing architecture was built around the assumption of a settlement gap.
