On a YoY basis, net interest income increased by THB 274.7 million or 3.9% mainly driven by loan expansion and an increase in interest income on investments. These were partially offset by lower net fee and service income of THB 213.1 million, or 18.6% YoY, largely attributed to lower fee income from insurance brokerage. Total other operating income decreased by THB 449 million or 18.1%, mainly from lower net gains on financial instruments measured at fair value through profit or loss, partially offset by higher gains on investment and gains on sale of non-performing loans.
Operating expenses increased by THB 554.4 million or 9.7%, mainly from higher impairment loss on properties for sale, as well as taxes and duties. This resulted in a higher cost to income ratio of 60.6% in 9M2023 compared to 53.2% in 9M2022.
Net interest margin (NIM) over earning assets stood at 2.6% in 9M2023, compared to 2.7% in 9M2022, arising from higher cost of funds.
