Thailand's central bank is intensifying regulatory oversight of non-bank lenders, targeting interest rate practices across P-Loans, nano-finance, and vehicle chattel mortgages. The sector has grown rapidly from 280 billion to 470 billion baht over five years, now representing 55% of total credit. The BoT will scrutinize licensing compliance, including cases where nano-finance licenses (max 33% interest) are misused for personal loans (capped at 25%), and aims to align rates with actual collateral risk, particularly for vehicle pledges. This regulatory tightening aims to strengthen consumer protection and standardization in a sector that increasingly serves underbanked populations previously denied access to traditional commercial bank credit.
