What happened: SBI’s FY27 Q1 profitability, interest metrics, and balance-sheet scale

State Bank of India (SBI) reported standalone net profit after tax increasing 10.2% year-on-year to ₹21,121 crore for the first quarter of FY27. SBI linked the rise in profit to higher net interest income (interest earned on loans and investments minus interest paid on deposits and borrowings), while SBI’s reported net interest margin (margin between interest earned and interest paid, expressed as a percentage) eased slightly during the quarter.

SBI’s standalone Q1 FY27 interest and balance-sheet figures reported were:

Net interest income (NII): up 15% year-on-year to ₹46,992 crore.Net interest margin (NIM): eased by 1 basis point to 3% in the quarter (1 basis point = 0.01 percentage point).Lending (loan book): ₹50.5 lakh crore, up 18.6% year-on-year.Deposits: ₹60 lakh crore, up 9.7% year-on-year.

Background and earlier position: how NPA ratios and NII/NIM typically interact

In bank analysis for UPSC GS3, Non-Performing Assets (NPAs) indicate credit stress. Banks track gross NPA (before provisioning) and net NPA (after provisioning). A change in NPA ratios often influences provisioning costs and can affect profitability alongside interest-income and margin dynamics.
