Evolution
The digitisation of banking is not merely a channel shift — it is a fundamental restructuring of cost curves, competitive dynamics, and customer expectations that is reshaping the entire industry.

The Digital Shift
Banking is undergoing its most profound structural transformation since the introduction of ATMs — driven simultaneously by customer behaviour, technology capability, and new entrants.
The transition from branch-centric to mobile-first banking has compressed cost curves dramatically. Digital-native banks operate at cost-to-income ratios of 35–42%, versus 55–65% for legacy incumbents — a structural advantage that compounds over time.
Meanwhile, fintech challengers have unbundled the traditional bank product stack — attacking the most profitable segments (payments, personal lending, FX) with superior UX and lower prices, forcing incumbents to respond through their own digital investment or acquisition.
Global digital banking users surpassed 3.6 billion in 2025. Mobile banking transactions now account for over 70% of all retail banking interactions at major global banks.
Key Drivers
Four structural forces are accelerating digital banking adoption and reshaping competitive dynamics.
Neobanks & Challengers
Digital-native banks have accumulated hundreds of millions of customers — but profitability remains the defining challenge.
Neobank Landscape — 2025
Selected Players| Bank | Customers | CIR | Profitable? |
|---|---|---|---|
| Nubank (Brazil) | 105M | 38% | Yes — since 2023 |
| Revolut (UK) | 45M | 42% | Yes — since 2021 |
| Chime (US) | 38M | 51% | Near breakeven |
| N26 (Germany) | 8M | 68% | Not yet |
| Monzo (UK) | 9M | 61% | Yes — since 2024 |
AI & Automation
Artificial intelligence is the next major cost and revenue lever — early movers are opening a structural efficiency gap.
Digital Outlook 2026
The pace of digital transformation will accelerate — the gap between leaders and laggards is becoming a structural, not cyclical, performance divide.
- → Embedded finance — Banking products embedded into non-financial platforms (e-commerce, mobility, healthcare) will grow to $7T by 2030.
- → GenAI deployment — Banks deploying generative AI at scale in 2026 — targeting compliance, code generation, and personalised advice.
- → Branch rationalisation — Top-5 US banks closed 2,400 branches between 2020–2025. Further consolidation expected as digital reaches 85%+ penetration.
- → Consolidation — M&A activity accelerating — larger digital banks acquiring specialised fintechs to fill product gaps and expand distribution.
- → Regulatory scrutiny — Regulators globally tightening oversight of AI models in credit and the operational risks of cloud-concentration.
By 2027, CIR will be the primary valuation differentiator among retail banks — institutions that have made the digital investment will trade at a structural premium to those still carrying legacy cost structures.
