Krungsri Auto
Krungsri Auto is the automotive finance business associated with Bank of Ayudhya, offering car loans, motorcycle finance, refinancing, dealer finance, and related consumer-credit products. It is a major profile entity in Thailand's vehicle-financing ecosystem because auto sales are closely tied to credit availability, used-car values, household debt, and dealer networks. Its market role spans new and used vehicles, conventional cars, motorcycles, and increasingly financing considerations around EV adoption.
What this company actually does
Krungsri Auto is the automotive finance brand of Bank of Ayudhya (Krungsri, SET:BAY), a wholly owned subsidiary of MUFG (Japan). Krungsri Auto provides hire-purchase and leasing for new and used passenger cars, motorcycles, commercial vehicles, and EV units, distributed through Toyota, Honda, Isuzu, and independent dealer networks across Thailand. Auto-loan portfolio estimated at THB 250-350B, making Krungsri Auto one of Thailand's top-3 auto-finance originators alongside TBANK (Thanachart) and Krungthai Bank auto-loan divisions.[, ]
Household debt dynamics are the dominant operating variable. Thai household debt exceeded 90% of GDP as of 2024; BoT responsible-lending regulations and macroprudential measures are tightening approval criteria and LTV limits. Used-car collateral values collapsed in 2023-2024 as Chinese EV imports compressed secondhand prices for ICE vehicles, raising 90-plus-day past-due rates on existing used-car portfolios. Krungsri Auto's credit quality trajectory tracks more closely to used-car resale indices than to new-vehicle sales volume.[, , ]
Business segments
New car HP
New vehicle hire-purchase
Hire-purchase origination for new passenger cars and pickup trucks through Toyota, Honda, Isuzu, Mitsubishi, and independent dealer networks. New-vehicle finance is lower-risk (factory-fresh collateral) but margin-compressed by competition from captive finance arms (Toyota Leasing Thailand, Honda Finance).
Used car
Used-vehicle and pre-owned finance
Used-car HP is the higher-yield, higher-risk segment. Thai used-car resale values have been under pressure since 2023 as Chinese EV imports reduce demand for secondhand ICE vehicles. NPL risk is concentrated in the 2021-2023 origination cohort on used-car collateral.
Motorcycle
Motorcycle hire-purchase
Motorcycle finance serves lower-income borrowers and gig-economy workers. Higher default rates than passenger car; shorter loan tenor (24-36 months). Key distribution is through Honda Big Wing, Yamaha, and independent motorcycle dealers in rural provinces.
Refinancing
Vehicle refinancing and title loans
Refinancing of existing vehicle collateral provides liquidity to borrowers against vehicle equity. Growing segment as Thai household-debt stress drives need for short-term liquidity. Competes with pawnshops and digital-lending platforms on speed and accessibility.

Key drivers 2025-2026
Used-car collateral value stabilisation
Chinese EV import compression of ICE used-car residuals is the primary 2024 credit-quality headwind. Stabilisation of used-car auction prices is a prerequisite for NPL normalisation in Krungsri Auto's book.
BoT responsible-lending and LTV caps
BoT macroprudential settings on auto-loan LTV and debt-service-to-income ratios constrain origination growth; any regulatory relaxation would expand the addressable market for high-yield used-car finance.
EV hire-purchase origination growth
As Chinese EV brands (BYD, GWM, SAIC) expand Thai dealer networks, Krungsri Auto needs EV-specific underwriting and residual-value models. EV HP origination is both a volume opportunity and a new credit-risk frontier.
MUFG capital support and BAY parent integration
MUFG ownership of BAY provides capital stability and funding cost advantages. MUFG's regional strategy for Thailand auto-finance may influence Krungsri Auto's growth ambition and risk-appetite setting.
Watchpoints
Credit quality
Used-car NPL cycle
Special-mention and 90-plus-DPD loans on used-car collateral are the leading indicator. Watch Krungsri Auto's stage-2 migration rate in BAY quarterly results. Collateral-value deterioration precedes reported NPL peaks by 2-3 quarters; used-car auction indices are the forward signal.
Regulation
BoT responsible-lending tightening
BoT household-debt reduction policy can restrict refinancing origination and tighten new-loan approval rates even when dealer demand for volume is high. Any extension of responsible-lending relief measures to auto-finance would directly affect Krungsri Auto approval rates and origination pace.
EV disruption
EV residual values and underwriting risk
Battery degradation uncertainty, model obsolescence from rapid EV technology cycles, and limited Thai EV remarketing infrastructure create residual-value risk for EV HP portfolios. Krungsri Auto's underwriting models for EV collateral are still being calibrated against limited Thai EV resale data.
