In short

Peer-to-peer lending platforms match people with money to people who want to borrow, taking a fee for the matching and often for servicing the loans.

RISK-FORWARD, and three things belong before anything else. First: you are the lender. Not a depositor, not a saver — a lender making unsecured loans, generally to borrowers who could not obtain bank credit on the same terms, and if they do not repay, the loss is yours. Second: a provision fund is not a guarantee. It is a pot of money set aside by the platform, sized on expected losses, and it can be exhausted — which is most likely to happen precisely when defaults rise, meaning the protection weakens exactly when it is needed. Third: platforms have failed, and a reader should know what happens to their loans if the one they use does. This article explains the mechanics and the arithmetic. It names no platform and recommends nothing.

The economics are legible and the yields look attractive against deposit rates. The comparison to a deposit is the error the whole article exists to correct, because a deposit is a claim on a bank and frequently protected by a compensation scheme, while this is a loan book with the credit risk sitting on the reader.

Where the yield comes from, and what removes it

The portal's credit principle applies unchanged: extra yield is compensation for something. Here the something is specific and identifiable. Borrower credit risk. These borrowers are typically served less well by banks — because of thin credit history, business type, or affordability assessments — so the rate reflects a genuinely higher probability of not being repaid, which is the high-yield principle in a retail setting. No deposit protection. A deposit-taking bank is generally covered by a compensation scheme; a peer-to-peer loan is not, and part of the yield premium is the absence of that safety net. Illiquidity. Loans run to a term, and exiting early depends on a secondary market that may not exist or may be suspended — a facility that can be switched off is not a market, the same point the crowdfunding article made. And platform risk, which is the exposure with no analogue in a savings account. Now what removes the yield, and this is where the arithmetic matters. Defaults are not an accident; they are a rate. A platform advertising 9.5% expects some proportion of loans to fail, and the honest figure is the yield after expected losses and fees. Four things a reader should compute or find before assessing any advertised rate. The default rate and how it is measured — annualised, cumulative, or by cohort, which are different numbers. The recovery rate on defaulted loans, since a 100% loss and a 40% loss are very different. Platform fees, charged on lending, servicing, or both. And the seasoning effect: a new loan book shows almost no defaults because loans have not had time to fail, so a young platform's reported default rate is systematically flattering and improves nothing. That last point is the most useful single item in this article, because it explains how an advertised track record can be accurate and misleading at once.

The provision fund, and platform failure

Many platforms operate a provision fund and it deserves precise treatment, because it is the feature most likely to be read as safety. What it is: money retained from borrower payments, held to compensate lenders for defaults. What it genuinely does: smooths ordinary, expected losses, so a lender does not experience each individual default directly — and that is a real benefit in normal conditions. What it is not: a guarantee. It is finite, it is sized against expected losses, and it is typically discretionary in application. And the structural problem: a fund sized for expected defaults is by construction insufficient for unexpected ones — so it works in the conditions where a lender needs it least and fails in the conditions where they need it most. That is not a criticism of any platform's integrity; it is what a fund of that design can do. Then platform failure, which requires four questions — the same four the portal has now applied to crypto custody, property platforms, farmland vehicles, and crowdfunding. Do you hold the loans or a claim on the platform? Where loans are held directly or through a segregated arrangement, they may survive the platform's insolvency; where the position is a claim on the platform, the lender is an unsecured creditor of a failed company. Is there a wind-down plan, and who administers it? Loans need collecting for years after a platform stops operating, and collection is labour, so someone must be paid to do it or it does not happen. Does the secondary market survive? Generally not. And is the platform regulated, for what activity, in your jurisdiction? What this article will not say is that peer-to-peer lending is a fraud. It performs a real function — funding borrowers banks have retreated from — the disclosure on regulated platforms is substantive, and a lender who diversifies across many loans, understands the default arithmetic, and treats the yield as compensation rather than as interest is making an informed decision. What it will say is that the reader is the lender, the provision fund is not a guarantee, the seasoning effect flatters young platforms, and the correct comparison is not a savings account but a portfolio of unsecured consumer or small-business loans — which is exactly what it is.

Worked example

Worked example

Worked example (fictional). Priya lends $20,000 across a platform advertising 9.5% gross. Year one, a good year. Defaults run at 3% of the book with 45% recovery, costing 1.65 points. Platform fees take 1.0 point. Her net return is approximately 6.85%a real return, meaningfully above a deposit rate, and honestly earned for accepting credit risk. Year three, a downturn. Defaults rise to 9% and recovery falls to 25%, costing 6.75 points. The provision fund absorbs the first 2 points and is then exhausted, leaving her to bear 4.75. After fees, her return is approximately 3.75%less than half the good year's, and it would have been 1.75% without the fund; and she cannot exit, because the secondary market has been suspended as other lenders try to do the same thing. The provision fund covered part of the bad year and was empty before the year was out — one more year at that default rate and it would cover nothing. The seasoning point. When Priya joined, the platform advertised a 1.1% historical default rate. That figure was accurate — and the loan book was fourteen months old, so most loans had not reached the age at which they typically fail. The mature default rate settled near 5%. Nobody misrepresented anything; the number simply could not mean what it appeared to mean. And the platform case. In year four the platform ceases trading. Priya's loans are held through a structure she never examined. An administrator takes over collection, servicing costs are deducted from recoveries, communication becomes quarterly, and the remaining term extends by two years. Her borrowers keep paying — and the loans still perform while the channel does not, which is a risk that exists only because the channel was there. (All names and figures fictional; parameters from this pillar's canonical set; annual return = gross rate − loss borne after any provision-fund cover − fees.)

Frequently asked

9 questions

Is peer-to-peer lending like a savings account?

No, and that comparison is the central error. A deposit is a claim on a bank and frequently protected by a compensation scheme. This is unsecured lending to borrowers who generally couldn't obtain bank credit on the same terms — if they don't repay, the loss is yours.

Why is the yield higher?

Four identifiable reasons: genuinely higher borrower credit risk; the absence of deposit protection; illiquidity, since exiting early depends on a secondary market that may not exist or may be suspended; and platform risk, which has no analogue in a savings account.

What should I check before believing an advertised rate?

Four things: the default rate and how it's measured (annualised, cumulative, or by cohort are different numbers); the recovery rate on defaults; platform fees; and the age of the loan book.

Why does loan-book age matter so much?

Because a new loan book shows almost no defaults — loans haven't had time to fail. So a young platform's reported default rate is systematically flattering. On the illustration here, an accurate 1.1% figure came from a fourteen-month-old book, and the mature rate settled near 5%. Nobody misrepresented anything; the number couldn't mean what it appeared to mean.

Does a provision fund protect me?

It smooths ordinary, expected losses, which is a real benefit in normal conditions. It isn't a guarantee: it's finite, sized against expected losses, and typically discretionary. The structural problem is that a fund sized for expected defaults is by construction insufficient for unexpected ones — so it works when you need it least and fails when you need it most.

What happens if the platform fails?

Ask four things: do you hold the loans or a claim on the platform; is there a wind-down plan and who administers it; does the secondary market survive (generally not); and is the platform regulated, for what, where. Note that collection is labour — someone must be paid to do it for years after a platform stops, or it doesn't happen.

Can the loans perform while the platform fails?

Yes. On the illustration, Priya's borrowers keep paying while an administrator takes over, servicing costs come out of recoveries, and the term extends by two years. The loans perform and the channel doesn't — a risk that exists only because the channel is there.

What does a bad year actually look like?

On the illustration: defaults at 9% with 25% recovery cost 6.75 points, the provision fund absorbs 2 and is exhausted, and the net return falls to about 3.75% — less than half the good year's, and with no ability to exit because the secondary market was suspended as other lenders tried to do the same thing. A second year at that default rate would find the fund empty.

Is there a sensible way to do this?

A lender who diversifies across many loans, understands the default arithmetic, and treats the yield as compensation rather than as interest is making an informed decision. The platform performs a real function, and disclosure on regulated platforms is substantive. The correct mental model is a portfolio of unsecured consumer or small-business loans — because that's what it is.
