Evaluating digital banking UX for India's 138M senior citizens — the most under-served, highest-CASA demographic in the financial system.
Measures friction in navigation depth, authentication steps, and information density for senior users.

India's Silver Economy represents a ₹4.8 trillion CASA opportunity that incumbent banks are systematically failing to retain. Our cognitive load analysis reveals that existing mobile banking interfaces impose 3–6 step authentication flows generating 58% of senior-segment complaints — directly translating into CASA ratio deterioration. Regulatory mandates under RBI's Digital Banking Guidelines (2024) require WCAG 2.2 AA compliance by Q4 FY26, yet 89% of sampled institutions remain non-compliant.
The remediation pathway involves neuro-inclusive UX redesign incorporating voice-biometric consent, progressive disclosure navigation, and behavioural anomaly detection calibrated to elder transaction patterns. Our AI TRiSM framework integration ensures that accessibility improvements do not inadvertently create new fraud vectors. Implementation of the FinWithDip Silver Audit Protocol is projected to improve senior CASA retention by ₹240Cr per tier-1 institution within 18 months, whilst achieving full regulatory compliance ahead of RBI enforcement deadlines. Neuro-inclusion is not a UX nicety — it is a material balance sheet lever.
