Refinitiv to cease TRYFIX

TRYFIX cessation

TRYFIX is an index that measures the Turkish Lira implied interest rate. The rate is published daily in overnight, 1-month, 3-month, 6-month and 12-month settings and is calculated using input data comprising market data from four brokers as well as other parameters.

In September 2022 Refinitiv issued a consultation paper on the future of TRYFIX. Following the consultation, Refinitiv concluded that cessation of TRYFIX is the most suitable outcome. Calculation and publication of all tenors of TRYFIX will permanently cease immediately following the final publication at 11:30 EET on Friday on 28 April 2023. Users should take into account this cessation notice and ensure their contractual and other arrangements linked to TRYFIX contain appropriate and robust fallback plans or other arrangements to address the cessation.

TWD DF USD/TWD Swap and Implied Interest Rate “TWDDF”

TWDDF is an index that measures the Taiwanese Dollar to USD Dollar foreign exchange and implied interest rate. The index is calculated and published daily when contributions from a minimum of 5 Taiwanese Banks are received.  The Refinitiv TWDDF rates are then published as both forward premium/discount reference rates and calculated implied interest rates. 

From the analysis and engagement performed regarding the use of Refinitiv TWDDF, Refinitiv believes the rates may be used by a small number of firms only for internal reference and checking purposes.  Feedback confirmed that alternatives are being widely used, such as broker data and TWDF= which also provides Taiwan Dollar Forward Reference rates.

Recognising changes in the market, limited use of the rates and the availability of alternatives, Refinitiv intends to cease the calculation and publication of Refinitiv TWDDF following the final publication at 11:30 Taipei CST on Friday, 30 JUNE 2023. Please refer to the consultation paper for details and how to provide feedback.

How It Works


For benchmarks that we administer, users of benchmarks enter into licensing agreements with Thomson Reuters in order to access timely data or use of the benchmark for financial products. Licensing and corresponding fees vary according to intended use of the data, delivery mechanism, as well as the time of delivery (real time versus delayed access).

Benchmark data is made available on Eikon, through our financial data feeds as well as through third-party market data vendors and other redistributors.
