THRISSUR, India — Private sector lender The South Indian Bank Ltd. has released its provisional South Indian Bank business update for the first quarter of the fiscal year ending June 30, 2026, reporting a 17.01 percent year-on-year expansion in its gross advances portfolio. The regulatory disclosure, submitted to Indian stock exchanges on July 1, 2026, indicates a steady operational momentum in credit deployment and a notable improvement in low-cost core deposit accumulation.
This early quarterly growth report provides critical insights into the banking sector's health at the start of the financial period. The data demonstrates a resilient retail and corporate borrowing market, which continues to drive commercial balance sheet expansion despite broader macroeconomic challenges.
Accelerating Credit Allocation and Loan Advances
According to the official exchange filing issued by the bank's secretarial department, South Indian Bank's gross advances climbed to Rs 104,366 crore as of June 30, 2026. This represents a substantial volume increase from the Rs 89,198 crore recorded during the corresponding quarter of the previous fiscal year. On a sequential basis, gross advances grew by 4.08 percent from the Rs 100,274 crore registered at the close of the previous quarter on March 31, 2026.
The banking firm highlighted an underlying technical adjustment that affected its year-on-year growth trajectory. During the quarter ended March 31, 2026, the financial institution executed a technical loan write-off amounting to Rs 1,048 crore.
The bank clarified in its statement that had this technical write-off action not been taken, the normalized year-on-year credit growth benchmark for gross advances would have reached 18.00 percent as of June 30, 2026. This adjustment indicates that the organic velocity of credit origination remains higher than the baseline reported figures reveal.
Deposit Accumulation and CASA Ratio Expansion
On the liability side of the balance sheet, the South Indian Bank business update revealed stable momentum in capital mobilization. Total deposits held by the banking entity rose to Rs 125,786 crore at the end of the June 2026 quarter, marking an 11.39 percent year-on-year increase from the Rs 112,922 crore baseline logged on June 30, 2025. Sequentially, total deposits expanded by approximately Rs 2,440 crore over the Rs 123,346 crore reported in March 2026.
Crucially for profitability margins, the lender reported an acceleration in its low-cost Current Account Savings Account (CASA) portfolio. Total CASA deposits grew by 14.61 percent year-on-year, finishing the quarter at Rs 41,493 crore compared to Rs 36,204 crore in the prior year's matching period.
This targeted expansion in lower-yielding liabilities successfully pushed the bank's aggregate CASA ratio up to 32.99 percent. This represents an improvement over both the 32.06 percent registered in June 2025 and the 32.12 percent reported in March 2026. A higher CASA ratio helps insulate commercial banks from rising wholesale interest rates by reducing the overall blended cost of funds.
