Fine art as an alternative asset in 2026: provenance, valuation and exit

Is fine art an investable asset, or simply a valuable one? For most works it is the latter. Art can hold significant value, but it produces no income, trades in a thin, opaque market and carries high transaction and holding costs. What makes a work underwritable for a family office, private bank or fund is not the price paid but the evidence behind it: defensible attribution, clean title, documented condition, sound custody and a realistic route to sale.

The market in 2025: modest growth, concentrated at the top

Global art sales rose 4% to an estimated $59.6 billion in 2025, according to the Art Basel & UBS Art Market Report 2026, prepared by the research firm Arts Economics and published on 12 March 2026. The United States (US) accounted for 44% of sales by value, the United Kingdom (UK) 18% and China 14%.

The recovery was uneven (see table). Online sales fell to $9.2 billion, their lowest level since 2019, and 56% of the value of fine art auctions held in sale rooms came from lots above $1 million. Headline growth says little about how easily an average work can be sold.

In Poland, Artinfo.pl reported auction turnover of 427.1 million Polish złoty (PLN) in 2025, down almost 5% from 2024, across 568 auctions, 15% more than a year earlier. About 24,000 of roughly 50,000 works offered found buyers. The top lot, Jacek Malczewski's Rzeczywistość (1908), sold for 22.2 million PLN including buyer's premium.

What separates an investable work from a valuable one

Price records what one buyer paid. Investability depends on whether the next buyer, lender or insurer will accept the same evidence. Five tests do most of the work.

Attribution is not permanent. Artist foundations can withdraw from authentication: in October 2011 the Andy Warhol Foundation announced it would close its authentication board after spending over $7 million defending a lawsuit. Elsewhere, attribution rests on individual experts, whom the market can reassess.

Provenance and title risk is legal, not aesthetic. The Best Practices for the Washington Conference Principles, released on 5 March 2024, state that a sale by a persecuted person between 1933 and 1945 can be treated as equivalent to an involuntary transfer. In the US, the Holocaust Expropriated Art Recovery (HEAR) Act of 2025, signed into law on 13 April 2026, removed the original sunset date of 31 December 2026 and aims to stop claims being dismissed on time-based defences. A search of the International Criminal Police Organization (INTERPOL) Stolen Works of Art Database, which holds almost 57,000 items, is a baseline rather than a clearance.

Cross-border rules add a further layer. Under Council Regulation (EC) No 116/2009, exporting a painting over 50 years old and valued above 150,000 euros (EUR) outside the European Union (EU) requires an export licence. National rules also apply: in Poland, a permanent export permit is needed for paintings older than 50 years and worth more than 40,000 PLN. Since 28 June 2025, bringing certain categories of cultural goods into the EU has required an import licence or an importer statement, depending on the category.

Technical analysis, such as pigment analysis, X-ray fluorescence (XRF) spectroscopy, infrared reflectography and dendrochronology (tree-ring dating of wooden panels), can show that a work is inconsistent with its claimed date but rarely proves authorship alone. New York's Knoedler gallery closed in 2011 after selling forged Abstract Expressionist paintings; a museum study of one found no anachronistic pigment. The weak point was provenance: an anonymous collector and no clear ownership history.

Custody, insurance and the cost of ownership

With no income to offset them, costs reduce the eventual outcome directly:

• Buyer's premium (the fee added to the hammer price, the price at which a lot is sold before fees). Sotheby's charges 28% up to $2 million in New York, 22% to $8 million and 15% above, after an increase in February 2026; Christie's schedule since September 2025 starts at 27% up to $1.5 million.
• Seller's commission and sale costs. Seller's commission ranges from 0% to 10% or more, with possible charges for insurance, shipping and restoration.
• Artist's resale right. In the EU, resale royalties run for 70 years after the artist's death on a sliding scale from 4% to 0.25%, capped at EUR 12,500 per sale.
• Insurance, storage and transport. Specialist cover, climate-controlled storage and fine-art shipping vary with value and location; price them from quotes, not assumptions.
• Compliance. In the EU, dealers, auction houses and free ports (duty-suspended storage zones) have anti-money laundering (AML) obligations for transactions of EUR 10,000 or more, so identity and source-of-funds checks are standard.

Illustratively, at a 28% buyer's premium and an assumed 10% seller's commission, a work bought at a $1 million hammer price must resell at roughly $1.42 million hammer just to recover its purchase cost, before holding costs or royalties.

Exit routes and timelines

Exit should be planned at acquisition. Public auction offers transparent price discovery but exposes a work to visible failure if unsold. Consignment involves an estimate, a reserve (the confidential minimum price), cataloguing and marketing ahead of a scheduled sale; Sotheby's remits proceeds within 45 days of the sale, provided the buyer has paid. Decision to cash typically takes months, not weeks.

Private sale through a dealer or auction house is confidential but offers narrower price discovery; such auction-house sales fell 5% in 2025. Art-secured lending provides liquidity without a sale: the Deloitte Private and ArtTactic Art & Finance Report 2025 projected the market for loans secured on art and collectibles at $33.9–40 billion by the end of 2025, and Sotheby's financing arm closed $900 million of asset-backed notes backed by art-secured loans in February 2026. Borrowing moves valuation risk into loan-to-value limits; it does not remove it. Tax on disposal varies by jurisdiction and structure.

Risks, stated plainly

Illiquidity comes first: demand is thin outside the top segment, and a work that fails at auction may be viewed differently afterwards. Valuation is subjective: appraisals are opinions, and in 2025 only 27% of wealth managers, 38% of collectors and 48% of art professionals reported high trust in art market data, according to Deloitte. Cost drag accrues whatever the outcome. Attribution and forgery risk can surface years after purchase. Title and regulatory risk, from restitution claims to export controls, can delay or block a sale.

Fractional and tokenized structures divide exposure to a work, usually held in a special purpose vehicle (SPV), into smaller units. They change the access point, not the asset: the risks above remain, and the structure adds its own fees and governance. Deloitte notes that such initiatives have yet to achieve widespread acceptance. In the US, fractional art interests have been offered as securities under the Securities and Exchange Commission (SEC) Regulation A; one offering circular calls the painting's value inherently subjective and cautions that its secondary market may not be an effective way to sell. In the EU, crypto-assets that qualify as financial instruments fall outside the Markets in Crypto-Assets Regulation (MiCA) and under financial-instruments rules.

What we watch next

• The Art Basel & UBS Survey of Global Collecting 2026, due on 8 October 2026, for collector spending and allocation.
• Autumn 2026 auction results under the higher buyer's premium schedules, especially sell-through below $1 million.
• Artinfo.pl's full-year 2026 figures for Poland, to test whether the 2025 stabilisation in volume holds.
• Early claims under the revised HEAR Act.
• Application of the EU Anti-Money Laundering Regulation (AMLR) from 10 July 2027, and the growth of art-secured lending and its securitisation.

OKETO evaluates art and other alternative assets with a focus on attribution, title, condition, custody and exit, and considers ownership or financing structures only where appropriate and subject to structure, jurisdiction and eligibility.
