The buyback guarantee is not a guarantee. Here is what it actually is.

A buyback guarantee sounds like insurance. It is not insurance. It is a promise from a company to repurchase a loan from you if the borrower stops paying, usually after 30 or 60 days.

The question nobody asks at the point of signing up is: which company?

The promise comes from the party most likely to break it

On almost every marketplace platform, the buyback is issued by the loan originator — the lender that made the loan in the first place. That company earns money when its loans perform and loses money when they do not.

So consider what has to happen for you to need the buyback. Borrowers have stopped paying, in volume. The originator's revenue has fallen. Its own funding costs have probably risen. And it is at exactly that moment that you are asking it to write you a cheque for every loan that went bad.

This is not a hypothetical. It is what happened across the sector in 2020, when several originators on Mintos were suspended and investors discovered that a buyback obligation from an insolvent company is an unsecured claim in a foreign bankruptcy proceeding.

What separates a real structure from a marketing line

There are a small number of things that make a buyback meaningfully stronger, and they are all visible before you invest:

• A group guarantee. The parent company, not just the local lending entity, stands behind the obligation. Check whether the guarantor publishes audited accounts.
• A cash reserve held outside the originator. Money that is already set aside cannot be spent by a company in trouble.
• A monitoring or collection account. This is the strongest mechanism in the sector: the platform can intercept borrower repayments directly if the originator fails, which means recovery does not depend on the originator's cooperation.
• Skin in the game. The originator retains a first-loss piece of every loan, so it takes the first hit rather than you.

These layers are only as good as their record. On Income Marketplace, the one lender failure so far — ClickCash, suspended in November 2022 — was about half recovered by September 2026, partly with Income's own money. The structure helped; it did not make investors whole quickly.

What to do with this

Do not treat a buyback badge as a risk-removal device. Treat it as a claim on a specific company, and go and look at that company. If you cannot find out who the guarantor is and whether they publish accounts, you have learned something important about the platform.

And size the position accordingly. A 60-day buyback that pays reliably for five years is genuinely valuable. It is also exactly the kind of thing that works perfectly right up until the moment you need it most.
