Why it moves share
Deposit share is the single biggest constraint on a credit union's ability to lend and grow members. Repricing the whole book to chase rate destroys margin on the 80% of balances that never move; a ring-fenced digital sub-brand lets you compete on APY for marginal, rate-shopping money while protecting core relationship pricing. Fund the loan pipeline at the margin instead of buying wholesale, and convert a slice of rate-chasers into full members over time. This is a solid incremental-funding spread play, not a transformational one: at ~3% share growth (~$13M on a $500M CU) and a ~2.1% net spread the NI lift is real (~+5-7 bps ROA) but modest, and the book is built on hot money that leaves the moment you are not top-decile — so the governance workstream is load-bearing, not decorative.
The execution roadmap · 3 sequenced phases
Days 0–30Stand up the ring-fenced brand
Owner: Digital / Product + Compliance
- Confirm Field-of-Membership bridge eligibility (associational / community / underserved) with legal + compliance sign-off
- Launch the digital-only brand + account-opening funnel, reusing your existing DAO stack
- Wire ACH funding, external transfer, and KYC/CIP automation with synthetic-ID controls
Dependencies: Field-of-Membership bridgeDigital account opening
Leading indicator: Funnel live; cost-per-funded-account baseline set
Days 31–60Price it, fund it, deploy it
Owner: Treasury / ALM + Marketing
- Set tiered APY engineered for a controlled blended cost of funds below your wholesale alternative
- Turn on acquisition (rate-comparison marketplaces + paid) against the cost-per-account target
- Deploy inflows into the loan pipeline at ~70% mix — not idle cash
Dependencies: Loan pipeline / MBL cap headroom
Leading indicator: Net-new deposits; blended cost of funds vs wholesale; deployment yield spread
Days 61–90Convert to members, govern the risk
Owner: Member Growth + Risk / ALM
- Run the cross-sell bridge from single-product saver to full membership (checking, loan, card)
- Stand up liquidity/ALM guardrails and NCUA Part 740 cross-brand insurance-aggregation disclosures
- Monitor 90-day retention and the loan-to-share trend; tune tiering if hot money outpaces deployment
Dependencies: ALM/treasury modeling capacity
Leading indicator: Single-to-multi conversion rate; 90-day retention; loan-to-share trend
