IDS Co., Ltd. (Headquarters: Oshu City, Iwate Prefecture, Representative Director: Tatsuya Sugawara, hereinafter "IDS") is pleased to announce that its financial management system, COURAGEUX, will release a new function on July 25, 2026, that is the first in Japan (*1) to acquire floating interest rates, including Zengin-kyo TIBOR rates, via API and automatically link them to COURAGEUX. This function will streamline interest rate change processing during rate revisions by acquiring floating interest rates such as TIBOR rates, Long-Term Prime Rates, and Short-Term Prime Rates via API and importing them into COURAGEUX. (*1) As of July 1, 2026, based on our own research. [Background of Development] In recent years, due to changes in the interest rate environment, the importance of accurately grasping fluctuations in corporate borrowing interest rates and promptly reflecting them in management has increased for corporate finance departments. Particularly in borrowing contracts linked to TIBOR, the applicable rate fluctuates according to the interest rate revision cycle for each contract, such as one month or three months. Therefore, finance personnel had to manually check the published rates and input/transfer them into borrowing management systems or Excel each time a revision occurred. As the number of such transactions increases, the confirmation load grows, and the risk of transcription errors or missed updates arises. COURAGEUX has supported the centralized management of information related to corporate finance, including borrowings, lendings, corporate bonds, and interest rate swaps. With the new TIBOR integration function, we will further streamline rate management operations for floating-rate contracts, contributing to the standardization and improved accuracy of finance department operations.
