UBS has raised its target price for Bajaj Finance to Rs 6,800 from 6,500 while maintaining a 'sell' rating, citing concerns over high credit costs and a structural decline in return on assets. The brokerage highlights worsening borrower repayment trends and weakened underwriting in business loans, predicting a fall in RoA due to changes in the asset mix. Despite expectations for customer growth through the Liberalised Remittance Scheme and aggressive cross-selling, the firm's expansion into dealer-driven products may limit cross-sell potential.
