Concerns on funding wholesale asset growth with wholesale deposits and impact on margins, given corporate loan growth at 6% QoQ while gold/SME flattened.

Management explained that building a wholesale franchise requires investments in compressed NIM initially, but as long as full-year NIM guidance of ~3.75% and ROA of 1.3%-1.5% are met, it's acceptable. Each business will be held to deliver ROA once gold mix falls below 45%. They are building transaction banking to improve RAROC and eventually ROA.

Long-term strategic progress questioned: despite 6 years, retail assets and liabilities haven't grown materially; what has changed?

Explained the SBS 2030 vision with five pillars; technology decision delay of 2.5 years was the only shortfall. The bank has executed on governance, compliance, human capital, and now with tech completed, the scale phase FY27-FY30 will deliver compounding growth. Retail build will be traditional, avoiding DSAs and digital partnerships for sustainability.

Key themes

Scaling phase, retail franchise build, gold mix glide-path.

How the narrative shifted

Scaling phase after tech transformation: With technology overhaul complete, the bank is now entering a scale-up phase from FY27 to FY30, leveraging new systems to build retail liabilities, transaction banking, and a balanced franchise.
Gold mix glide-path to diversify: Gold loans, currently 54% of advances, will be reduced to ~50% in FY27 and ~30% by 2030 as wholesale and eventually retail grow, transforming the bank from a gold loan-heavy entity to a diversified bank.
Retail liability build delayed but planned: The CASA and retail deposit franchise will start contributing meaningfully only from FY28 onwards; until then, the bank funds growth with bulk deposits at higher cost, which management deems acceptable to seize asset-side opportunities.
Cautious on SME/unsecured amid macro risk: Due to tariff uncertainty, supply chain disruptions, and job concerns, the bank has raised credit appraisal bars for SME and will not enter unsecured retail until FY28, prioritizing asset quality over growth in these segments.
Transaction banking for wholesale franchise: Investments in transaction banking systems and teams aim to improve RAROC and eventually ROA from the wholesale portfolio, shifting from opportunistic lending to relationship-driven, fee-supported banking.
Seasonal NIM/asset quality volatility: Q1 is seasonally the weakest quarter for NIM and asset quality; management considers Q1FY27 NIM the floor and expects improvement, with SME slippages to be largely recovered in subsequent quarters.

Operational commentary

Technology transformation completed; bank now entering scale phase with new product launches and retail liability acquisition channel rolled out.
Gold loan share at 54% of advances; planned glide path to ~50% by end-FY27 and ~30% by FY2030 as other businesses grow.
Transaction banking systems (trade, supply chain, CMS) partially in place, remaining expected in 3-4 months to support wholesale franchise.
Retail deposit franchise build to start reflecting in CASA growth only from FY28; FY27 CASA ratio targeted to be maintained, growth to outpace term deposits from FY29.
Wholesale and corporate banking grew strongly; wholesale loan growth guided 35-40% for FY27, gold loan growth 30-35%.
SME/BLG portfolio approach remains cautious due to macro uncertainty and tariff risks; some slippages this quarter expected to be upgraded in Q2/Q3.
Repledger business (LAS against gold collateral) discontinued voluntarily; portfolio wound down from ₹2,100 Cr to ₹60 Cr, causing retail disbursement degrowth.
Insurance business temporarily slowed to strengthen compliance and avoid mis-selling; resumption expected from Q2.
Branch network at 868 branches and 835 ATMs as of Jun-26.
