Key Takeaways

What This Masterclass Covers

01

Number 1: The Correlation, 0.04

Art's correlation to the S&P 500: 0.04 (Sotheby's Mei Moses, 80,000+ pairs). Citi GPS found -0.04. Renneboog and Spaenjers, across 1.1 million transactions: -0.03. Three independent studies. Three different data sets. Same conclusion. Art moves to its own rhythm.

02

Number 2: The Tax Number, 0%

Zero tax while you hold it. Art is classified as a non-wasting chattel under the Taxation of Chargeable Gains Act 1992. No income tax. No unrealised gains tax. CGT only on disposal. And if any single item sells for £6,000 or less, the gain is completely exempt. Post-October 2024 Budget, the gap between art's treatment and virtually everything else has widened.

03

Number 3: The Lending Market, £40 Billion

The global art-secured lending market: roughly $40 billion, growing at 12% a year. Loan-to-value ratios: 40 to 60%. No disposal event. No CGT. You keep the art. The answer to "I can't sell it quickly if I need cash" is straightforward: you don't have to sell it.

04

Numbers 4 & 5: ~20% Enhancement, Zero New Supply

A UCL-affiliated study of 81,891 transactions found a 20% art allocation enhances risk-adjusted returns by approximately 20% (ArXiv pre-print, caveat noted). And new supply from deceased artists? Zero. Not low. Not constrained. Zero. Rising demand meets permanently fixed supply.
