Suppliers Bargaining Power
Wholesale funding dependence
NAB relies on domestic and offshore wholesale markets for roughly 27% of its funding, supplying term funding beyond deposits. Large institutional investors can demand higher spreads in volatile conditions, lifting funding costs as seen in 2023–24 spread widenings. Central bank facilities (RBA/ESF) can temper spikes but are conditional and temporary. Diversification across tenors and currencies mitigates risk, though market liquidity concentration remains a leverage point.
Core tech and cloud vendors
NAB depends on a concentrated set of core banking, cloud and cybersecurity vendors for stability and scalability, creating supplier pricing power and contractual leverage. Hyperscalers AWS and Microsoft Azure held roughly 54% combined cloud market share in 2024 (AWS ~31%, Azure ~23%), amplifying switching complexity and lock-in from long implementation cycles. Strategic partnerships can trade price concessions for faster innovation and greater resilience.
Payment networks and rails
Card schemes (Visa/Mastercard, ~80% global card volume) and domestic rails like NPP and clearing systems are essential inputs for NAB, with scheme fee structures and rule changes directly affecting unit economics and merchant margins. Limited credible alternatives to these networks heighten supplier influence, though NAB’s seats in industry governance and scheme boards partially mitigate fee/rule pressure.
Specialist talent and contractors
Specialist risk, data, engineering and compliance talent markets are tight in Australia and New Zealand, giving suppliers leverage as wage inflation and retention premiums rise; Australia wage price index grew about 3.7% year to June 2024 and New Zealand WPI ~3.4% in Q2 2024. Outsourcing and nearshoring ease supply but add coordination and control risk, while automation and AI can gradually reduce dependency and unit labour costs.
- WPI: AUS 3.7% (y/y Jun 2024)
- NZ WPI: ~3.4% (Q2 2024)
- High retention premiums = supplier leverage
- Outsourcing helps but adds coordination risk
- Automation = medium-term dependency reduction
Data, analytics, and credit bureaus
Credit bureaus (Equifax, Experian, Illion), market data and analytics platforms underpin underwriting and monitoring for banks including NAB; proprietary scoring and unique datasets increase supplier leverage by differentiating risk models. Open Banking/Consumer Data Right rollout (2019–2020) broadened sources but integration and compliance costs remain material. Multi-sourcing reduces concentration risk yet curbs volume discounts and bargaining power.
- Three major bureaus: Equifax, Experian, Illion
- Open Banking (CDR) rollout 2019–2020 expanded data access
- Proprietary scores raise supplier leverage; multi-sourcing trades scale for resilience
Moderate supplier power: 27% wholesale funding, ~54% hyperscaler share, ~80% card volume
NAB faces moderate supplier power: 27% wholesale funding dependence raises sensitivity to market spreads; hyperscaler concentration (AWS ~31%, Azure ~23% = ~54% combined in 2024) and card schemes (~80% global volume) create switching costs; tight tech/compliance talent (AUS WPI 3.7% y/y Jun 2024, NZ WPI ~3.4% Q2 2024) increases wage pressure, while multi‑sourcing and central bank backstops limit extremes.
| Supplier | Metric | 2024 |
|---|---|---|
| Wholesale funding | Share of funding | 27% |
| Cloud hyperscalers | AWS+Azure | ~54% (AWS31/AZ23) |
| Card schemes | Global volume | ~80% |
| Wage pressure | WPI Australia/NZ | 3.7% / 3.4% |
| Credit bureaus | Major providers | Equifax, Experian, Illion |

Customers Bargaining Power
Rate-sensitive depositors
Rate-sensitive depositors can switch rapidly as the RBA cash rate rose to about 4.35% in 2024, squeezing net interest margins and forcing NAB to match higher term and bonus saver rates. Real-time onboarding and comparison sites increase price transparency, shortening switching cycles and elevating acquisition churn. Incentive cycles and term promotions raise short-term acquisition costs, while product innovation (features, digital tools) can partly shift competition away from pure rate.
Mortgage customers with options
Australians and New Zealanders refinance often, with the broker channel handling about 66% of new home loans (MFAA 2023), increasing switching. Cashback offers—commonly up to A$3,000 in 2023–24—and headline rate discounts drive price-based competition. Faster digital conditional approvals (often within 24 hours) compress decision windows and boost buyer leverage. Loyalty is fragile absent clear service differentiation.
SMEs and corporates via RFPs
Larger SMEs and corporates run competitive RFPs for lending, transaction banking and markets, shrinking NABs pricing power as bundled pricing and relationship limits cap margins. Sophisticated treasury teams routinely negotiate covenants and fees, leveraging market comparators. Modular platforms and APIs, reinforced by the 2024 expansion of Australias Consumer Data Right for banking, make switching and onboarding faster and cheaper.
Multi-banking and low switching costs
Customers increasingly multi-bank; NAB serves over 7 million customers (2024), and Open Banking via Australia's CDR exceeded 4 million consents by 2024, lowering switching friction. Buyers unbundle products, choosing best-in-class fintechs for payments, lending and wealth. Retention now hinges on deep ecosystem integration and data-driven personalization to raise switching costs despite low transactional barriers.
- Multi-banking prevalence — >7M NAB customers (2024)
- Open Banking impact — CDR >4M consents (2024)
- Unbundling — product-by-product buyer choice
- Retention drivers — ecosystem + personalization
Digital experience expectations
Users benchmark NAB against fintech and big-tech UX; outages or poor journeys drive churn even when NAB is competitively priced, as Australia’s big four banks hold about 80% of deposits and face intense digital comparison pressure.
- Self-service and 24/7 support are table stakes
- Superior app features can offset modest price gaps
- Digital reliability directly affects retention
Rising rates, broker dominance and CDR fuel mass switching, squeezing bank margins
Customers have high bargaining power: rate-sensitive depositors and over 7M NAB customers (2024) switch quickly as the RBA cash rate rose to ~4.35% in 2024, squeezing NIMs. Brokers handle ~66% of new home loans (MFAA 2023) and CDR consents exceeded 4M (2024), lowering switching costs. SMEs run competitive RFPs and unbundle services, forcing price and feature competition.
| Metric | 2023–24 |
|---|---|
| NAB customers | >7M |
| CDR consents | >4M |
| Broker share (home loans) | 66% |
| RBA cash rate | ≈4.35% |
| Typical cashback | up to A$3,000 |

Rivalry Among Competitors
Big Four head-to-head
NAB competes intensely with CBA, Westpac and ANZ across mortgages, SME and institutional business. Big Four hold about 80% of the Australian mortgage market (APRA 2024); NAB’s share is ~12.9% (APRA 2024). Market-share shifts hinge on pricing, service and risk appetite while scale advantages meet similar cost-transformation agendas. Differentiation rests on sector specialism and relationship depth.
Regionals and mutuals pressure niches
Bendigo and Adelaide Bank, BOQ and credit unions focus on community and SME niches, leveraging local branches and tailored underwriting to win loyalty; mutuals held roughly 10% of Australian deposits in 2024, pressuring majors. Aggressive deposit pricing by regionals can force rate matching, while fintech and aggregator partnerships extend their digital reach.
Fintech and non-bank lenders
Specialist fintechs and non-bank lenders increasingly target unsecured loans, BNPL, merchant acquiring and asset finance, with fintechs capturing roughly 10% of unsecured consumer lending by 2024 and Australian BNPL volumes near AU$16bn; faster onboarding and alternative data now set customer expectations for near-immediate decisions. Higher funding costs are often offset by lower overheads, and growing collaboration and white‑label deals blur competitive lines with NAB.
Price wars in mortgages
Price wars see owner-occupier and investor loans facing ongoing discounting and cashbacks (industry cashbacks up to around 3,000 AUD in 2024), while broker channel, which handled about 60% of new home loans in 2024, compresses NIMs through upfront commissions and clawbacks; NAB retention teams target churn at repricing anniversaries and advanced risk-based pricing models become a core competitive weapon.
- Cashbacks ~3,000 AUD (2024)
- Broker share ~60% (2024)
- NIM pressure via clawbacks/commissions
- Retention at repricing anniversaries
- Risk-based pricing sophistication
Service, trust, and brand battles
Reputation and compliance track records strongly influence customer choice; with the Big Four holding c.80% of Australian banking assets (2024), NAB’s regulatory record directly affects retention and corporate clients.
Outage avoidance and rapid fraud response shape trust; ESG and responsible lending act as competitive signals, while transparent fees and clear communication can win share without deepest discounts.
- Reputation: regulatory outcomes
- Trust: uptime & fraud response
- ESG: lending policies
- Pricing: transparency over cuts
Big Four hold ~80% of mortgages; brokers and fintechs squeeze margins
NAB faces intense rivalry from CBA, Westpac and ANZ with the Big Four holding ~80% of mortgages; NAB’s mortgage share ~12.9% (APRA 2024). Regionals and fintechs (BNPL AU$16bn, unsecured lending ~10% fintech share 2024) pressure pricing and digital service. Broker channel (~60% new loans 2024) and cashbacks (~AUD3,000) compress margins; reputation and uptime drive retention.
| Metric | 2024 |
|---|---|
| Big Four mortgage share | ~80% |
| NAB mortgage share | ~12.9% |
| Broker share | ~60% |
| BNPL volumes | ~AUD16bn |
| Cashbacks | Up to AUD3,000 |
SSubstitutes Threaten
Capital markets disintermediation
Larger corporates increasingly issue bonds or securitise receivables to bypass bank loans, reducing demand for NAB’s large-ticket lending given NAB’s gross loans of about AUD 380bn in 2024. Investment banks and private credit funds, with global private credit AUM near US$1.5tn in 2023, offer tailored capital solutions that erode bank market share. Ancillary fee income from advisory, syndication and transaction banking can partly offset lost net interest spreads.
Non-bank and fintech credit
Shadow lenders now deliver mortgages, SME loans and BNPL with streamlined UX that attracts millions of Australian customers and double-digit growth in originations through 2023–24, competing on speed rather than price.
Platform lenders have substituted bank lines for specific segments—especially microbusinesses and younger buyers—capturing material share of new flows.
Strategic partnerships and referral agreements let NAB convert this threat into origination pipelines and fee income.
Payments via wallets and platforms
Digital wallets and PSPs reroute transactions from bank channels; global digital wallet users exceeded 4 billion in 2024 (Statista), pressuring traditional flows. Interchange and acquiring margins face compression as platforms negotiate lower fees and BNPL growth reduces card volumes. Embedded marketplace payments erode bank visibility and customer touchpoints. NAB can counter by owning merchant relationships and offering integrated acquiring services.
Superannuation and wealth platforms
Superannuation platforms and robo-advisers are diverting savings—Australian super assets reached about A$3.6 trillion in 2024, while digital advisers hold a fast-growing but still small share (under 2% of assets), eroding bank deposit flows. Cash management tools and wrap accounts act as low-friction substitutes for traditional deposits and term products, and fee-transparent models pressure legacy wealth margins. NAB can partially defend share via integrated advice, bancassurance bundles and platform cross-selling.
Crypto and alternative stores of value
While niche, stablecoins (~US$155B market cap in 2024) and crypto ETFs (spot BTC ETFs >US$150B AUM by end-2024) create alternative payment and savings avenues and can siphon yield-seeking deposits during high-return cycles. Regulatory moves (EU MiCA implementation and US clearer ETF regimes in 2024) may legitimize select use cases. Bank-issued tokens or blockchain rails could internalize these substitutes through tokenized deposits or rails integration.
- Market size: stablecoins ~US$155B (2024)
- ETF flows: spot BTC ETFs >US$150B AUM (end-2024)
- Regulation: MiCA/US ETF clarity 2024
- Mitigation: bank-issued tokens/blockchain rails
Non-bank credit, digital wallets and stablecoins squeeze bank NII and deposit base
Non-bank capital (private credit US$1.5tn 2023) and shadow lenders reducing NAB loan demand; NAB gross loans ~A$380bn (2024). Digital wallets 4bn users (2024), BNPL and PSPs compress interchange and NII. Super assets A$3.6tn (2024) and robo <2% divert deposits. Stablecoins ~US$155bn (2024) create episodic yield competition.
| Substitute | 2024 metric | Impact |
|---|---|---|
| Private credit | US$1.5tn (2023) | Loan displacement |
| NAB loans | A$380bn | Scale at risk |
| Digital wallets | 4bn users | Fee/NII pressure |
| Superannuation | A$3.6tn | Deposit diversion |
| Stablecoins | US$155bn | Yield competition |
| Robo-advisers | <2% assets | Wealth share shift |
Entrants Threaten
High regulatory barriers
High regulatory barriers from APRA and RBNZ deter new entrants: Basel-derived LCR minimums of 100% and CET1 targets have seen major Australian banks hold roughly 11–13% CET1 in 2024, raising capital needs for newcomers.
Full ADI licensing demands robust governance, compliance and APS-aligned frameworks, while RBNZ’s core funding ratio (75% phased in by 2024) and prudential supervision create substantial fixed costs.
These requirements protect incumbents like NAB from rapid displacement by increasing scale and regulatory compliance advantages.
BaaS lowers tech hurdles
BaaS cuts tech hurdles so brands can launch bank-like products in weeks instead of the typical 12–18 months, letting entrants focus on UX while licensing regulated back-ends. That shifts the principal barrier to customer acquisition and CAC economics rather than infrastructure. Incumbents like major banks can also offer BaaS themselves, co-opting new challengers and compressing margin opportunity for pure-play entrants.
Big tech and platform risk
Large platforms with combined market caps exceeding US$7 trillion in 2024 can scale payments, lending and wallets rapidly, leveraging distribution to millions of users; in Australia contactless transactions accounted for about 79% of card payments by number in 2023, enabling fast adoption. Regulatory scrutiny from ACCC and CDR slows full banking entry but not incremental feature creep, and co-marketing or co-branded products often precede deeper moves.
Non-bank lenders scaling up
Non-bank lenders scale using warehouse lines and RMBS rather than deposits, enabling rapid growth and allowing cherry-picking of higher margin segments; they accounted for about 13% of new Australian mortgage originations in 2023–24, showing material share gains. Lighter regulation lets them adjust pricing faster, but reliance on wholesale funding and securitisation creates fragility in downturns, limiting sustained threat.
- Funding: warehouse lines/RMBS over deposits
- Market share: ~13% of new mortgages (2023–24)
- Strategy: segment cherry-picking, higher ROE
- Constraint: funding fragility in stress
Open banking-enabled specialists
Data portability from Australia’s Consumer Data Right (CDR) launched in 2020 enables niche entrants in PFM, credit decisioning and SME tools to wedge into value pools without becoming full banks; aggregators can capture the customer interface while the Big Four still hold about 80% of retail deposits in 2024, so NAB must defend with superior APIs and partner ecosystems.
High capital: CET1 11–13% keeps banks ahead of platform entrants
High regulatory capital/ADI costs (CET1 ~11–13% in 2024) raise entry scale, protecting NAB.
BaaS and CDR cut tech time-to-market; platform giants (>US$7T market cap in 2024) and 79% contactless share (2023) enable feature entry, not full-bank displacement.
Non-bank lenders ~13% of new mortgages (2023–24) grow via RMBS but depend on fragile wholesale funding.
| Barrier | Metric | Implication |
|---|---|---|
| Regulation | CET1 11–13% (2024) | High capex/scale |
| Tech | BaaS/CDR; platforms >US$7T | Feature entrants |
| Non-banks | 13% mortgages (23–24) | Funding fragility |
