The blue chips held and gained while the broad market fell — a textbook flight to liquidity in a softening market.

For press & citation

The wsky1 Collectable Scotch Index, a benchmark built from 431,813 auction lots, opened its first reading up +10.5% over the trailing twelve months — even as 58% of all tracked expressions fell over the same period. The collectable Scotch market has bifurcated: liquidity and value concentrated into a blue-chip core while the long tail, and Japanese whisky in particular, sold off hard.

What the index measures

The CSI Blue-Chip 10 is a lot-volume-weighted basket of the ten most actively traded expressions in the dataset — the deepest, most liquid corner of the secondary market. Weighting by lot volume means the index reflects where money actually moves, not where a single trophy bottle spiked.

Equal-weighted, the basket reads +11.3%; the median constituent move is +7.5%. Lot volume is the weight, so the liquid core dominates the reading.

The story behind the number

1

Blue chips up, broad market down

Across the trailing twelve months, 58% of all tracked expressions fell and only 33% rose (of 5,012 with a clean year-on-year comparison). Yet the blue-chip basket was up ~10%. The market isn't uniformly weak — it's narrowing. Collectors and flippers are crowding into the liquid, name-brand core and abandoning the speculative long tail.

2

Japanese whisky led the fallers

The steepest declines were Japanese: Yamazaki Distiller's Reserve −99.2% (to a £40 median), Suntory White −98.3%, Japanese blended malt broadly −96%+. The post-2020 bubble continues to deflate at the entry/mid tier, even as a few aged Yamazaki bottlings move the other way — the category is splitting just as the wider market is.

3

Activity is concentrated — and concentration is liquidity

Macallan alone changed hands 2,873 times in the window — more than the next two distilleries combined. Trading is dominated by a familiar roster (Macallan, Springbank, Ardbeg, Bowmore, Glenfiddich). For a collector, liquidity is the asset: these are the bottles you can actually sell when you want to.

Notable lots & movers

Methodology
  • Universe: 431,813 public auction lots across 31+ houses (Scotch Whisky Auctions, Whisky Hammer, Just Whisky, Whisky-Online, Bonhams, Sotheby's, Christie's and 28+ more), covering 22,607 catalogued bottles. Refreshed daily.
  • Prices: median hammer price per expression, GBP, excluding buyer's premium.
  • Index construction: the CSI Blue-Chip 10 is the ten most actively traded expressions over the reporting window, weighted by lot volume. The index is rebased to 1,000 at the trailing-twelve-months base (Mar–May 2025).
  • Window: three months to May 2026 (Mar–May 2026), compared with the same window one year prior for the 12-month figure.
  • Why the 12-month horizon leads: monthly medians shift with the mix of lots that happen to trade, so 1M/3M readings are volatile and reported only for transparency. The 12-month change is the stable signal.
  • Not investment advice. Auction data is informational; past hammer prices do not predict future value.
