Overview of Banking and Financial Services Industry

What is BFSI?

  • BFSI is an acronym for Banking, Financial Services and Insurance. This covers a whole gamut of activities and business models.
  • Wiki defines – “ BFSI comprises commercial banks, insurance companies, non-banking financial companies, cooperatives, pensions funds, mutual funds and other smaller financial entities. Banking may include core banking, retail, private, corporate, investment, cards and the like ”

The definition above is still the right starting point. The useful next step is to sort every product by who holds the risk and who gets paid. A non-banking financial company lends without taking deposits. A payments firm moves money without lending it. A marketplace sells someone else’s loan or policy and keeps a commission. That last distinction is most of what people now call fintech.

Four pillars inside BFSI

PillarWhat it sellsWho keeps the riskWho pays
Retail and SME bankingDeposits, payments, cards, personal and home loans, current accountsThe bank’s own balance sheetBorrowers pay interest. Card spend generates interchange. Some accounts pay a fee.
Wholesale and marketsTrade finance, cash management, equity and debt capital markets, M&A advisory, custodyThe bank’s balance sheet, or the client’s, depending on the productCompanies and funds pay interest, advisory fees, and a fee in basis points of assets.
Asset management and pensionsMutual funds, ETFs, retirement products, wealth adviceThe investor. The manager does not promise the return.The client pays a fee in basis points of assets. Some funds also charge a performance fee.
InsuranceLife, health, motor, property, and reinsuranceThe carrier, then the reinsurer for the slice that is passed onThe policyholder pays premium. The carrier invests the float before claims are paid.

Banking inside the original definition already splits into core banking, retail, private, corporate, investment, and cards. Core banking is the system of record. The others are products that sit on top of it.

If you opened the ten sites, these are the products you should be able to name, and the way each institution is paid. Several names are groups, so the homepage is only the front door.

SiteProducts and servicesHow that institution is paid
ChaseChecking and savings, credit cards, mortgage, auto loans, investing, business banking, merchant servicesNet interest on loans funded by deposits, card fees and interchange, treasury and wealth fees
Credit KarmaFree credit scores, card and loan offers, insurance quotes, tax filing through IntuitLenders and insurers pay per approved customer. The score is the free hook.

New-age startups in BFSI and fintech

The firms below were mostly founded after 2008. They pulled one product out of a universal bank, shipped it as an app or an API, and charged for a thinner slice. By 2025 the cohort that started this around 2010–2018 was large enough to matter on its own. Venture funding into fintech fell 41% that year, to $26.1 billion, while revenue at the 50 largest profitable fintechs rose 29%, to $187 billion.

Four rails made that possible: India’s UPI and account aggregator, Brazil’s Pix, Europe’s open-banking rules, and US card economics that still pay the card issuer a share of each swipe. A startup can sit on those rails without owning a branch network.

Chase, SBI, HDFC, and ICICI earn a net interest margin because they hold loans against deposits. Chime, Plaid, Policybazaar, and a pure payments gateway do not. Nubank, SoFi, Monzo, and Revolut started as a slice of the bank and later took a licence so they could keep the margin. That licence, more than the app, is what turns a fintech into a bank.

Nine revenue models

Every firm in the directory uses one of these as its main engine. Most add a second engine once they have customers. The question to ask of any pitch is: who pays, on what event, and who eats the loss if the customer does not repay.

ModelWho paysWhat triggers the chargeFirms
Payments take-rateThe merchant or the businessA percent of volume successfully collected or paid out, sometimes plus a fixed feeStripe, Adyen, Razorpay, PhonePe, Paytm, dLocal, Flutterwave, Wave, Toss
Card interchangeThe merchant’s bank, through the card networksEach swipe or tap. The issuer’s share is the neobank’s revenue.Revolut (largest slice), Chime, Monzo, Ramp
FX and spreadThe person or company converting currencyA fee and a thin markup on the mid-market rate, or interest on balances parked between transfersWise, Airwallex. Revolut also has an FX line.
Net interestThe borrowerInterest received on loans and cards, minus interest paid on depositsNubank, SoFi, WeBank, Tyme. Interest was 21.6% of Revolut’s 2025 income.
BNPL feeThe merchant, then the shopper if they finance for longerA merchant discount higher than a normal card rate, plus interest on instalment loansKlarna, Affirm
BrokerageThe trader, the market maker, or bothA flat or zero commission, payment for order flow, margin interest, or a spread on cryptoZerodha, Groww, Robinhood
Software and APIThe bank or the fintech, not the end consumerA subscription, a per-connection fee, or a platform fee per cardPlaid, Marqeta, Mambu
DistributionThe lender or insurer whose product is soldA commission when a loan or policy is completed. The app does not keep the credit or insurance risk.Policybazaar. Also a second engine at PhonePe, Paytm, and Credit Karma.
Insurance premiumThe policyholderPremium comes in. Claims and reinsurance go out. The carrier keeps a fee or an underwriting margin.Lemonade. Policybazaar never takes the claim.

Revolut’s 2025 income mix

Revolut is the cleanest public illustration of a super-app bank. Fee lines were 76% of turnover, so the group is less tied to interest rates than a traditional bank. No single line was more than a quarter of income. Business accounts were 16% of income. Revenue was £4.5 billion, up 46%. Profit before tax was £1.7 billion. Net profit was £1.3 billion. Retail customers reached 68.3 million. A secondary sale implied a $75 billion valuation.

Income lineShare of 2025 group income
Card payments22.2%
Interest income21.6%
Subscriptions15.7%
Wealth14.7%
FX13.4%
Other12.4%

Latest revenue, selected firms

These numbers are approximate and they do not share one fiscal year. They are here so the revenue models above have a sense of scale.

FirmApproximate annual revenueWhat the figure is
Stripe$20 billion2025 private-company estimate, not a filing
Nubank$10 billion2025. Published roundups range from about $9.4 billion to $10.6 billion.
Revolut£4.5 billion (about $5.7 billion)Reported 2025 revenue. Dollars use about 1.27 USD per GBP.
WeBank$5.4 billionThird-party 2025 comps for the Tencent-linked digital bank
Klarna$3.5 billion2025 figure cited in public comps
Wise$2.5 billionReported FY2026 net revenue, year ended 31 March 2026, up 19%
Adyen$2.2 billion2025 net revenue, as cited in results roundups
Zerodha₹8,847 crore (about $1.1 billion)FY25 revenue, roughly flat into FY26. Profit after tax about ₹4,200 crore. Rupees converted at ₹84 per USD.
PhonePe₹7,115 crore (about $0.85 billion)FY25 revenue from operations, from its DRHP
Razorpay₹3,783 crore (about $0.45 billion)FY25 operating revenue. A confidential IPO filing was reported in 2026.

PayPal and Block are larger, and they are older than this cohort. Block’s gross revenue is swollen by bitcoin that passes through the Cash App, so it is a poor comparison with the net revenue figures above. Wise is worth a separate line: FY2026 cross-border volume was $244 billion, the cross-border take rate was 0.52% (down from 0.58% the year before), and almost half of net revenue came from card spend and interest on balances rather than from the transfer itself.

How to read the next fintech you see

Name the rail it sits on: cards, UPI, Pix, SWIFT, a broker exchange, or an insurance licence. Name the payer: merchant, borrower, policyholder, or another financial firm. Then ask whether losses stay with the startup. If they do, it is a balance-sheet business, and capital and bad debts matter more than app downloads. If they do not, it is a take-rate, software, or commission business, and the risk sits at a bank, NBFC, or insurer whose brand you may never see on the homepage.

Figures mix fiscal years, currencies, and gross versus net revenue. Stripe’s $20 billion is an outside estimate. India’s numbers are rupee operating revenue. This is a study map for the original BFSI note, not a ranking for investment.
