The valuation is free. That should be the first clue.

At most lenders, when you borrow against a painting, an independent appraiser sets its value. The lender pays for that distance. They want a number they did not produce, because the number decides how much they can safely lend.

Sotheby's Financial Services does it differently. The appraisal is complimentary, carried out in-house, anchored to the auction house's own low and high estimates. The firm that values your Rothko also writes the loan against it. And if you miss a payment, the same firm can sell it.

Three roles, one hand. Valuer, lender, liquidator.

The figures are not small. SFS reports 5.5 billion dollars in loans made to date, individual loans running from 1 million to 200 million, typically at half the appraised value. A 10 million dollar collection releases 5 million in cash, often within weeks, no credit check, no financial disclosure. The art is the only thing underwritten.

Here the structure tightens. The loan-to-value ratio rests entirely on the appraisal. A lower valuation means a smaller loan and a thicker cushion for the lender. The firm setting the number is the firm protected by it. When the same house may one day sell the work, a conservative estimate today is not caution. It is positioning.

None of this is hidden, exactly. It is simply never named as a conflict. The appraisal arrives as a courtesy. The loan arrives as a relationship. The sale, when it comes, arrives as a service. Each step is framed as the house doing you a favour, and at no point does anyone write down that the favour has a direction.

In 2023 a collector in Ohio put that argument before a federal court, alleging Sotheby's had undervalued his Gentileschi and his Van Dyck while acting as both appraiser and lender. The claim is contested. But the filing placed a question on the public record that the art-lending world prefers to keep off it.

A valuation is meant to be a fact about the work. At SFS it is also a fact about the lender's exposure, and the two do not always point the same way.

The question, then, is not whether Sotheby's is honest. It is structural, and it outlasts any individual's good faith: whom does an appraisal serve, when the appraiser stands to gain from the sale?

Sotheby's is the visible version of the problem, an appraiser with a stake in the number. The invisible version is the appraisal you give your own painting, the one no specialist can correct for you: The art investment risks nobody prices.
