First-pass narrow read — primary edge in Switching Costs. Provisional, single-pass evidence.

Provisional score · subject to modification based on new evidence

RBL Bank Ltd. scores 4.61 on MoatSCORE 6.0 — a narrow moat in Banks. This is a first-pass note: the dimensional read and the filing receipts below come from a single GFIP evidence pass, not the full two-pass deep corpus behind our flagship deep dives. Provisional — published free while the deep version is queued.

The teardown

Seven dimensions of moat

Ordered by contribution. Each dimension carries a verified filing quote, graded [M] mechanism or [O] outcome.

D2Switching Costs5.5
M · Mechanism Verified verbatim

“The focus is on deposits less than INR3 crores, which grew faster at 15% year-on-year and 4% sequentially to INR61,632 crores and now constitutes 51.5% of the total deposits”

RBL Bank Ltd. · Earnings Call · p.4
D5Intangible Assets5.3
M · Mechanism Verified verbatim

“Focus on building granularity in retail deposit franchise; deposit growth in FY24-FY26 led by retail”

RBL Bank Ltd. · Investor Presentation · p.39
D1Network Effects5.2
M · Mechanism Verified verbatim

“We'll exit March with around 600 branches. And by next March, a year after, it will be around 800. And by third year, we'll be exiting 1,000 branches. It is our own RBL branch bank.”

RBL Bank Ltd. · Earnings Call · p.9
D4Price Discretion5.2
M · Mechanism Verified verbatim

“We do expect cost of deposits to further decline in Q4 and therefore, should help to marginally improve the margins even though the full impact of the December repo rate cut will come in Q4 of this financial year.”

D8Ungoverned RiskUnscored · Layer 2.5

D8 rating: ADEQUATE. Not part of the moat score — it governs the cost of equity and the fade window. First-pass; not yet deep-reviewed.

The barrier gate

The barrier gate — first-pass

Replication — can a rival copy it?5.5
How hard it is for a rival to copy the edge (first-pass estimate).
Bypass — can a rival route around it?5.0
How easily a rival can route around the edge (first-pass estimate).

Effective barrier 5.0 — below 6, so the band is capped narrow. First-pass estimate.

What would change our mind
  1. Deep two-pass review. This draft rests on a single GFIP evidence pass; the full 10-year AR + concall corpus may move the read.

  2. The barrier gate. A firmer replication or bypass estimate is the most likely thing to shift the band.

  3. Adverse events. Any governance, regulatory or funding shock captured in D8 could re-rate the fade window.
