IOSCO Statement of Compliance
Definitions
SIBOR is the rate at which an individual Contributor Bank could borrow funds, were it to do so by asking for and then accepting the interbank offers in reasonable market size, just prior to 11:00 a.m. Singapore time.
SOR is the synthetic rate for deposits in Singapore Dollars (“SGD”), which represents the effective cost of borrowing SGD synthetically by borrowing US Dollars (“USD”) for the same maturity, and swap out the USD in return for the SGD.
Calculation Methodology
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.
Details are shown in the table below:

will be the last day of publication for 1M and 3M SIBOR as announced in ABS-SFEMC and SC-STS’ December 2020 response paper.
will be the last day of publication for SOR across all tenor settings, following the UK Financial Conduct Authority’s announcement in March 2021 that the overnight, 1-month, 3-month, 6-month and 12-month USD LIBOR settings, which are used in SOR, would cease to be provided by any administrator or be no longer representative immediately after 30 June 2023.
was the last day of publication for the 6M SIBOR. 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 31 December 2024.
was the last day of publication for the 12M SIBOR. The 12M SIBOR was discontinued 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”.
Fallback Rate (SOR) is the primary fallback rate that will first apply upon the discontinuation of SOR after 30 June 2023. Similar to SOR, Fallback Rate (SOR) is an FX-implied rate based on actual qualifying transactions in the USD/SGD FX swap market reported by Reporting Brokers and a USD interest rate.
The final Fallback Rate (SOR) publication date for each tenor is the date corresponding to an Original SOR Rate Record Day of 31 December 2024 for that tenor, as projected in the table below:
