Thai financial institutions are projected to pivot significantly toward wealth management services over the next three years as decelerating loan demand and compressed interest rates trim profitability from conventional lending operations. According to an industry analysis by CGS International Securities (CGSI), expanding into wealth management allows banks to scale non-interest fee income effectively while bypassing the credit underwriting risks tied to traditional loan books. Market data compiled at the close of 2025 indicates that Thailand possesses an untapped demographic of roughly 517,674 prospective wealth management clients, representing an estimated $30.6 billion (THB1.02 trillion) in investable assets held across retail savings and fixed-deposit accounts.
The research identifies Kasikornbank (KBANK) and SCB X (SCB) as the primary beneficiaries of this structural shift, pointing to their advanced digital ecosystems, sophisticated client segmentation strategies, and established private banking frameworks tailored for high-net-worth and ultra-high-net-worth segments. This strategic momentum builds on a three-year trajectory of rising wealth management fee revenues across KBANK, Krung Thai Bank (KTB), and SCB. By 2025, wealth management accounted for 5.8% of total operating income at SCB and 5.5% at KBANK—leading the country’s top four banking groups—leaving both institutions exceptionally well-positioned to experience earnings growth driven by fee generation through 2028.
A demographic breakdown of Thailand’s investable wealth shows a distinct concentration at opposite ends of the affluent spectrum: mass-affluent clients holding deposits between $30,000 (THB1 million) and $300,000 (THB10 million) command 34.4% of total assets, while ultra-wealthy individuals with deposits exceeding $3 million (THB100 million) account for 36.2%. Because of their expansive domestic deposit networks, Bangkok Bank (BBL) and KTB sitting on the largest aggregate pools of prospective wealth management assets. However, CGSI notes that translating this baseline liquidity into active wealth portfolios will require both institutions to structurally prioritize wealth management, broaden their investment product suites, and scale up their relationship manager talent pools.
This pivot marks the continuation of a broader structural transformation under way since 2018, when the proliferation of free digital payment solutions eroded traditional transaction fee revenue pipelines. The current push is further accelerated by anticipated regulatory tightening surrounding core retail banking tariffs, making fee income from third-party mutual funds, brokerage operations, and bancassurance partnerships increasingly vital. While Thai banks are ramping up these efforts, they still trail regional benchmarks; wealth management accounted for 13% to 19% of non-interest income at Thailand’s four premier banks, whereas Singapore’s DBS led the ASEAN region by generating 57.5% of its 2025 non-interest revenue from wealth management fees following a 14.3% compound annual growth rate since 2017.
