The Passion Asset Index 2026

Passion Asset Advisory's 2026 reference separates market indices, auction records and collector-wealth estimates. Knight Frank reported a 0.4% fall in its Luxury Investment Index in 2025 and a 38.6% rise over the preceding decade. Neither figure is a collector's net return. Fees, taxes, insurance, storage and the exact asset can change the result substantially.

How have passion assets performed?

Use the same source, measure and time window when comparing performance. The table keeps unlike measures separate. Its rows cannot support a like-for-like ranking of categories.

We do not calculate a composite return from these unlike measures. Jets and yachts are not included in this performance table. For model-level watch evidence, see the F.P. Journe price dataset and auction ledger.

What are the record sale prices for passion assets?

These selected record-setting sales preserve the original sale currency and source. A record is the result of one asset, not a category average or a ceiling for future sales.

How big is the passion-asset market?

No single total covers every definition of passion assets. Annual sales, the value of assets held, and wealth-transfer forecasts measure different things. They should not be added together.

How much wealth do collectors allocate?

Deloitte's 2025 summary estimates an average 10.4% allocation among the art-collecting UHNW group it describes. That is not a universal 20% allocation to every passion-asset category. It is also not a recommended allocation for a reader.

What do investors think about passion assets?

Fladgate's research summary reports interest in diversification and perceived security. Its landing page describes more than 170 wealthy investors and 171 UK advisers, not a census of collectors. Survey beliefs do not establish that collectibles are safer than stocks or bonds.

How Passion Asset Advisory compares the sources

The office compiles this register; it does not produce the third-party indices. The CSV states the measure, observation period, publication date, unit and primary source. Blank values are not zero. Different index methods, currencies and sample selections limit direct comparison.

A collector's return depends on the purchase price, eventual sale price and ownership costs. Add buyer and seller fees, tax, insurance, storage, restoration or service, transport and currency effects. Thin trading and selective public results can hide losses or make an asset appear less volatile than it is. Past performance does not guarantee a future price.

There is no like-for-like, after-cost stock-market comparison in this dataset. A collection review can help organise evidence and sale options, but it does not replace regulated investment, tax or legal advice.

Passion Asset Index questions

Is the Passion Asset Index a financial product?

No. It is Passion Asset Advisory's research reference. It is not a fund, an investable benchmark or a recommendation to buy a category.

Did passion assets rise in 2025?

The picture was mixed. Knight Frank reported a 0.4% fall in its composite index for 2025. Art Basel and UBS reported 4% growth in art-market sales value, which is turnover rather than a return on individual works.

Can auction records value my collection?

Only relevant comparable sales help. Match the asset's identity, condition, provenance and sale context, then account for costs. Record-setting pieces are usually exceptional.

How often is this report updated?

Each edition keeps the observation dates and source publication dates visible. A page review does not turn a forecast into a result or refresh an older index.

Can the office review a watch collection?

The office can review collector-watch documents and comparable evidence under an accepted scope. A watch collection review starts at $2,500 for up to 15 watches. Other categories first need confirmed acceptance, then a written scope and fee. Any transaction mandate is separate and states the represented side and fees in writing.
