Report date: 2026-10-20 Event date: 2026-10-05 Event title: September Provisional Business Update

1. Flash Conclusion

Kotak Mahindra Bank's provisional September business update shows deposit expansion supporting a larger lending balance, but gives a mixed signal on funding quality. The Indian private-sector bank funds its commercial lending primarily through deposits. In this update, quarter-end total deposits grew faster than net advances quarter on quarter, while CASA balances grew more slowly than total deposits. Material FCNR(B) deposits under an RBI swap facility also affect the comparison. The headline growth therefore cannot be read simply as an improvement in the recurring low-cost deposit franchise.

This is a pre-earnings funding and balance-sheet memo. The Bank has announced an October 24 Board meeting to consider September-quarter and half-year financial results; those results remain pending as of this report. The preliminary figures do not update profit, asset quality, capital or regulatory liquidity. They support continued monitoring of the existing credit view, rather than a stronger conclusion about September loss-absorption capacity or funding stability.

2. What Was Disclosed

The October 5 exchange filing provides the Bank's deposits and advances for September 30, with June 2026 and September 2025 comparisons. All September figures are provisional and subject to statutory auditors' limited review. They are Bank balances, not a consolidated group balance sheet. End-of-period (EOP) and average series must be assessed separately.

Bank balances, INR crore Sep-2026 Jun-2026 Sep-2025 Sep-2026 YoY / QoQ
Net advances, EOP 577,094 512,249 462,688 24.7% / 12.7%
Net advances, average 546,963 494,854 447,809 22.1% / 10.5%
CASA, EOP 249,105 231,017 223,791 11.3% / 7.8%
CASA, average 226,469 216,898 198,250 14.2% / 4.4%
Total deposits, EOP 651,491 572,820 528,776 23.2% / 13.7%
Total deposits, average 606,234 558,891 510,138 18.8% / 8.5%

Source: October 5 official filing. Growth percentages are issuer-reported; comparisons use the corresponding EOP or average series. CASA denotes current and savings accounts.

The stronger EOP deposit growth than average deposit growth is relevant to durability. Average balances provide a broader view of funding held during the quarter, whereas the closing balance captures one date. The difference does not establish when money arrived, how long it will remain, or whether there was quarter-end window dressing. Those conclusions require flows, product composition and maturity information that this filing does not supply.

3. Funding Mix Matters More Than Headline Growth

Calculated EOP CASA as a share of total deposits fell to 38.24%, from 40.33% in June and 42.32% a year earlier. On matching average balances, the share was 37.36%, against 38.81% and 38.86%, respectively. CASA increased in absolute terms, so the signal is dilution of its share rather than a contraction in these balances. For creditors, that distinction matters: deposit volume is expanding, but the same figures do not establish that the lower-cost, more relationship-driven component is keeping pace.

A weaker CASA share can increase sensitivity to deposit pricing and renewal conditions, depending on the replacement funding. The actual September cost of funds, NIM and deposit tenor mix are not disclosed here. It would therefore be premature to convert the mix movement into a forecast of margin compression. Conversely, the rise in total deposits alone cannot establish improved deposit stickiness or cheaper funding.

The calculated ratio of EOP net advances to total deposits declined to 88.58%, from 89.43% in June, while remaining above 87.50% in September 2025. This is an arithmetic balance proxy, not a reported regulatory credit-deposit ratio or a liquidity-coverage measure. The sequential movement indicates that reported deposit growth kept pace with reported net lending at the closing date. It does not test liquidity under stress, encumbrance, collateral needs, deposit concentration or the maturity mismatch between assets and liabilities.

4. FCNR(B) Limits the Organic-Growth Interpretation

September EOP deposits include USD5.78 billion, approximately INR55,344 crore, of FCNR(B) deposits pursuant to the RBI's swap facility. EOP advances include USD1.68 billion, approximately INR16,110 crore, extended against those deposits by the Bank's international branches. Both amounts were translated at prevailing September-end exchange rates. The specified funding and associated advances therefore have different sizes and must not be removed from only one side of a comparison.

The disclosure establishes these balances' presence, not the full economics of the facility. It does not provide their contribution to average deposits or advances, a comparable June facility balance, deposit maturity buckets, swap pricing, hedge terms, or the disposition of all associated funds. A mechanical subtraction from September balances would consequently not produce verified organic or constant-currency growth. Nor can the difference between the two disclosed amounts be treated as freely available domestic liquidity: other deployment, settlement, currency and regulatory considerations remain unknown.

For senior creditors, the immediate question is how the Bank converts this funding into sustainable earnings while controlling liquidity and currency risk. The facility-linked balances may broaden funding, but they should be distinguished from recurring CASA acquisition and tested for maturity, cost and renewal behavior. A favorable closing loan-to-deposit proxy offers little protection if funding costs rise, maturities concentrate or asset deployment produces weak returns. The preliminary update does not establish that such deterioration has occurred; it identifies the information needed to judge that risk.

5. What To Watch Next

The October 24 results should reconcile provisional balances to final reported figures and explain funding costs, NIM, FCNR(B) economics and deployment. Updated LCR, NSFR, capital and risk-weighted assets are needed at their applicable entity scope. Asset-quality migration, slippages and provisions will show whether balance-sheet growth has preserved underwriting quality. The prior July flash's June-quarter capital and NPA figures remain historical context and must not be carried forward as September measurements.

The July flash also identified the KMIL loan-asset assignment and proposed Deutsche Bank India business acquisition as execution items. This business update does not establish their subsequent completion, contribution to September growth or effect on capital. The next results should separate any transaction or perimeter effects from recurring lending and deposit trends. No new rating-agency review, market-spread comparison or bond-documentation analysis was performed for this memo; conclusions on particular senior, subordinated or regulatory-capital instruments require their own terms and current evidence.

The practical next check is the announced October 24 results event, with follow-up on October 25. Until that event is verified, this operating update does not complete the scheduled quarterly financial-results review.
