ICE Futures Singapore issued Circular 26/014 on Monday, announcing changes to its Unofficial Settlement Duration and Volume Threshold settings across listed contracts.
The circular covers two fields that feed directly into how unofficial settlement prices are determined: the duration of the unofficial settlement window and the minimum trade volume required for a contract to receive unofficial settlement treatment.
Both settings affect desk-level processes. A change to unofficial settlement duration shifts the reference window used for end-of-day valuations, affecting margin calls, mark-to-market calculations and intraday risk checks. A revised volume threshold raises or lowers the trade-count hurdle a contract must clear before an unofficial settlement price is generated from market activity.
Existing structure
ICE maintains a contract-by-contract schedule of designated settlement periods, unofficial settlement durations and volume thresholds, published in its April 2026 reference document. That schedule spans energy, rates, equity index, carbon, agriculture and gas contracts.
Unofficial settlement durations in the April schedule are set at either five or 10 minutes depending on the product. Volume thresholds range from 15 to 500/250. ICE Brent Crude Futures and Options, for example, carry a 19:28–19:30 designated settlement period, a five-minute unofficial settlement duration and a 500/100 volume threshold. ICE One Month SOFR Index Futures sit at 19:58–20:00 with a 10-minute duration and a threshold of 20.
ICE Futures Singapore issued a separate circular in March covering a one-day timing adjustment for certain Singapore marker contracts on 2 April.
