The last day of publication for the 6M SIBOR was on 31 March 2022. This follows ABS-SFEMC and SC-STS’ December 2020 response paper that set out plans to discontinue all remaining tenors of SIBOR in a few years, starting with the 6M SIBOR in 2022, and the 1M and 3M SIBOR by end-2024. Given the March 2021 ICE Benchmark Administration (IBA)’s announcement, which would result in SOR discontinuation on 30 June 2023, ABS Co has updated the methodological fallback for 6M SOR effective 1 April 2022 to remove reliance on 6M SIBOR to allow 6M SIBOR to be discontinued separately from 6M SOR. The SC-STS confirmed on 31 March 2021 the 6M SIBOR discontinuation by 31 March 2022.

The last day of publication for the 12M SIBOR was on 31 December 2020 due to low market usage and the lack of underlying transactions underpinning this benchmark tenor, as mentioned in the July 2018 “Response to Feedback Received from the Consultation Paper on the Evolution of SIBOR

SIBOR stands for Singapore Interbank Offered Rates. An individual Contributor Bank contributes the rate at which it could borrow funds, were it to do so by asking for and accepting the interbank offers in reasonable market size, just prior to 11:00 a.m. Singapore time.

SOR is defined as the synthetic rate for deposits in SGD, which represents the effective cost of borrowing the SGD synthetically by borrowing USD for the same maturity, and swap out the USD in return for the SGD.

SIBOR is calculated in accordance with the Calculation Methodology for SIBOR. The published rate in respect of each tenor is the trimmed arithmetic mean of Contributor Banks’ contributions in respect of that tenor, rounded to the nearest five decimal places. The contributed rates will be ranked in order, the top and bottom quartiles will be trimmed, with the remaining rates averaged arithmetically. Each Contributor Bank's contribution carries an equal weight in the calculation, subject to the trimming.
