To enhance transparency and reliability of the Bangkok Interbank Offered Rate (BIBOR), the BOT has implemented a code of conduct for BIBOR contributors which suggests that BIBOR be quoted based on transaction data. As interbank transactions in the 9-month tenor records very thin volume and there is no financial contracts referencing such benchmark, the BOT has decided to discontinue the calculation and publication of the 9-month BIBOR since 1 April 2015.
