On October 27, 2022, it was decided that the spread to be calculated for the SHIR interest rate as needed for the Fallback Rate (which serves to transition existing Telbor transactions to SHIR interest rate transactions), will be based on the methodology implemented by ISDA for other IBOR interest rates. In this methodology, the spread is the median, over a period of 5-years, of the gaps between the Telbor and SHIR-Compounded in Arrears.
On February 23, 2023, it was decided that for the convention determined for SHIR IRS transactions, the interest calculation will be at an annual frequency and not quarterly, as is generally accepted for risk-free rates worldwide. This decision will be included in the convention files filled out for the SHIR rate for the Bloomberg screen specifications
On April 16, 2024 it was decided that the publication of all tenors of TELBOR will permanently cease immediately following a final publication on June 30, 2025.
On February 2025, it was decided that the convention determined for SHIR Cross Currency transactions will be a quarterly interest-rate frequency, as is currently generally accepted for CCS Telbor-SOFR transactions. This decision is also in line with the Bloomberg setup.
