Fundamental View
AS OF 24 Jul 2025Bangkok Bank is a family run conservative financial institution, with high capital and liquidity levels.
It acquired Indonesia’s Permata Bank in 2020 which resulted in a meaningful decline in its CET1 ratio to 14%. It is back to ~16% range and management aims to keep the CET1 ratio at ~16% in preparation for Basel III final reforms.
Profitability (ROA and ROE) has historically been below the industry average, due in part to higher exposure to the lower-yielding corporates segment that has resulted in a lower NIM. However, the returns gap has narrowed as this has supported its relatively better asset quality than most peers in a prolonged sluggish macroeconomic environment.
Business Description
AS OF 24 Jul 2025- Bangkok Bank was set up in 1944 and was listed on the Stock Exchange of Thailand in 1975. It is a family-run bank and the current President of the bank, Chartsiri Sophonpanich, is the grandson of the founder of the bank.
- It is the largest bank by assets in Thailand. It was briefly surpassed by Kasikornbank in 2018, but the Bank Permata acquisition has taken BBL back to No.1.
- The bank is corporate-loan focused, and the loan book was split 49% corporate, 16% SME, 12% retail, and 23% international as at June 2025. It is by far the most international amongst the Thai banks, with branches in 14 economies.
- BBL's overseas presence has been enhanced by the acquisition of Bank Permata, the 12th largest bank in Indonesia. Bank Permata's asset size is ~10% of that of BBL.
Risk & Catalysts
AS OF 24 Jul 2025We see a significant impact to the Thai economy from potential US tariffs, with ripple effects in the form of lower bank NIMs and higher credit costs than earlier guided for this year. Moody’s also downgraded its rating outlook on the Thailand sovereign, and consequently the Thai banks including BBL, to negative on 29 April 2025, citing increased risks to Thailand’s economic and fiscal strength, partly due to the potential impact of new US tariffs.
NIM pressure is set to continue into the coming quarters on the back of rate cuts to support growth. Loan growth will also remain middling across the Thai banks due to a focus on quality amid the current backdrop. However, we take comfort in BBL’s prudent provisioning, high loan loss buffers and safer large corporate book.
The acquisition of Bank Permata of Indonesia in May 2020 provides BBL with exposure to the high growth opportunities of the Indonesian market, but this also presents higher risks.

CreditSight View Comment
AS OF 22 Jul 2025Bangkok Bank’s strength has been its large corporate book and strong capital. It completed the acquisition of Indonesia’s Bank Permata (~12% of loans) in 2Q20 which reduced its CET1 ratio to 14%, but it has since rebuilt it to ~16%. Returns though have been lower due to thinner corporate margins, and we see greater NIM pressure on BBL than most peers from the turn in base rates. Disclosure from BBL is less than peers and bad loans jumped in 1H25. However, we take comfort in BBL’s strong loss buffers and large corporate book. We see a significant impact to the Thai economy and banks from potential US tariffs, with a bad tariffs outcome potentially leading to higher credit costs again. We have an Underperform rec.
