P2P & Marketplace Loan
Also known as: Peer-to-peer lending, Marketplace lending, Crowdlending
Retail investors funding consumer and business loans through a platform. Real credit risk, real yields, and a business model that has repeatedly discovered it was a lender all along.
1 · SnapshotThe one idea to remember
2 · BeginnerWhat is it, really?
A platform connects borrowers who want a loan with investors who want the interest. The platform underwrites, services the loan, and takes a fee — but historically did not lend its own money.
The investor's position is straightforward and easy to misjudge:
- You are the lender. A headline "8% return" is a gross interest rate before defaults, and defaults are not a tail event here — they are the expected cost of doing business.
- Diversification is not optional. One €5,000 loan is a coin flip. Five hundred €10 slices is a portfolio. Every platform's tooling exists to enforce this because concentrated retail lenders are the ones who lose money.
- The platform is not a bank. There is no deposit insurance, and in most jurisdictions no obligation to make you whole.
The honest framing: this is private credit in retail-sized pieces, with the same risks and less negotiating power.

The money is lent to strangers. The platform arranges and services it, and what happens if the platform itself fails is a separate question from whether the borrowers pay.
When you lend
- You → The platform Spread across many loans, usually automatically. Diversification here is a mechanism, not a suggestion.
- The platform → Borrowers Each borrower receives money from many lenders at once.
Every month
- Borrowers → The platform Collected by the platform, which keeps a servicing fee.
- The platform → You What reaches you is net of fees and net of whatever has defaulted.
If borrowers default
- Borrowers → You There is no deposit guarantee. A provision fund, where one exists, is a pot of money with a limit rather than a promise.
If the platform fails
- The platform → You Loans should be administered by a backup servicer. Whether that works in practice has been tested and the results have been mixed.

Which risks decide the outcome
Not how risky this is, and not a rating — there is deliberately no total. It says which of five failure modes drives what happens here, in the same order on all 129 products so they can be compared. This publication's own reading; see the notice below.

What decides it here. No deposit guarantee, no market to sell into, and a platform whose own failure is a separate question from whether the borrowers pay.

The arithmetic that decides the outcome
What the symbols mean
- rthe interest rate, per year
- Pa price, or a present value
- Dduration: how far a bond's cash flows sit in the future
- Lleverage, or a loss given default
- An unsecured consumer loan at 11% gross with a 6% default rate and 70% loss given default returns 11 − 4.2 − 1 ≈ 5.8% — before any recession.
- Losses are front-loaded and cyclical: defaults cluster 6–18 months after origination and rise sharply in downturns, precisely when investors want out.
- The default-probability tool and spread-duration calculators apply here unchanged — this is credit, wearing a website.
The three structural risks
| Risk | What it means |
|---|---|
| Credit | Borrowers do not repay — expected, priced, and underestimated by most retail lenders |
| Platform | The platform fails; who services and collects the loans then? |
| Liquidity | Secondary markets work in calm conditions and close in stress |
Platform risk is the one investors consistently miss. Ask a specific question: if this company entered administration tomorrow, who collects the loan payments and where do they go? Good platforms have a funded back-up servicer and hold loans in a bankruptcy-remote structure. Weak ones have a paragraph of intent.

What happened to the original model
The founding pitch was disintermediation: cut the bank out, split its margin between borrower and lender. What the sector actually discovered was that a bank's margin is mostly compensation for underwriting, servicing, funding stability and capital — and that removing the bank removes none of those costs.
- Institutional capital displaced retail. Credit funds and banks now provide most of the funding on major platforms, because they underwrite better and price the risk properly. Retail is a small and shrinking share of a market it invented.
- Platforms became balance-sheet lenders. Several acquired bank charters or now retain loans. The model converged back on banking, with better software.
- Adverse selection is structural. A borrower who can get bank credit generally does. The marginal platform borrower is the one a bank declined, and the platform's model must be better than the bank's to profit from that — a strong claim, not a given.
The regulatory reset
The sector's history includes genuine failures: the UK's largest platform wound down its retail business after loan-book problems; China's parallel market collapsed from thousands of platforms to essentially none after widespread fraud and losses. Regulators responded with appropriateness tests, marketing restrictions, capital requirements and, in several jurisdictions, caps on retail exposure. The market that remains is smaller, better supervised and considerably more honest about what it is.
How to evaluate one properly
- Cohort loss curves, by vintage. Not a blended average — a platform growing fast shows flattering aggregate numbers because young loans have not defaulted yet.
- Recovery data, not just default data. LGD moves the answer as much as PD.
- Skin in the game: does the platform hold a first-loss piece? Aligned incentives are worth more than any provision fund.
- Loan-level data availability. Platforms that publish full histories invite scrutiny; those that publish summary statistics have chosen not to.
The formulas above are standard textbook formulations, simplified for teaching. They explain the mechanism — they are not a valuation tool, and they will not reproduce a dealer’s price.

Close the page and give P2P & Marketplace Loan in four sentences. It takes a minute and it is the only way to find out whether reading it was enough.
- Who wants what — two parties wanted opposite things badly enough to write it down.
- What the contract obliges, and when — not the payoff; the obligation.
- Where the money comes from — name the source, or you have described a hope.
- What makes it lose — the ordinary way, not the dramatic one.
