Wool

Wool is the fleece shorn from sheep, and it was the original performance fibre long before synthetics: it insulates when wet, resists fire, wicks moisture, and is naturally elastic and odour-resistant. It is sold first as greasy wool, still carrying lanolin, grease, and dirt (a bale yields only around 60 percent clean fibre after scouring), and graded above all by fineness, measured in microns. Fine merino wool (roughly 17 to 24 microns) goes into next-to-skin apparel and commands a large premium; coarser crossbred wool (28 microns and up) goes into carpets, upholstery, and insulation. Australia dominates fine apparel wool, New Zealand the coarse carpet trade, and China produces the largest raw volume and is also the world's dominant processor and buyer.

Wool is one of the few soft commodities sold by a genuine auction system: brokers display tested lots and buyers bid in salerooms across Australia, with prices tracked by the AWEX Eastern Market Indicator (EMI), the benchmark quoted in Australian cents per kilogram clean. A futures market exists but is thin: the ASX lists greasy and fine wool contracts, descended from a Sydney wool-futures exchange founded in 1960, used mainly by growers and brokers to hedge rather than by a deep speculative crowd. Price turns on micron (the fine-coarse premium swings widely), Chinese demand, the price of competing synthetics, drought and flock size in Australia, and the apparel cycle.

The long arc is decline then premiumisation. Wool clothed the world and Australia famously "rode on the sheep's back," but cheap synthetic fibres from the 1950s, and cotton, pushed wool down to roughly 1 percent of world textile fibre. The 1970-to-1991 reserve-price scheme, a guaranteed floor defended by state buying, ended in a stockpile collapse that scarred the industry for a decade (see The Story). What survived reinvented itself at the top end: merino activewear and base layers sold on natural, biodegradable, temperature-regulating performance, plus enduring uses in carpets and a small, growing role as a premium natural building insulation, where wool's moisture buffering and flame resistance beat petroleum foams even though cost keeps it niche.

Wool is worth pausing on as one of the last big auction commodities. Auctions suit goods that resist standardisation: every lot differs by micron, yield, strength, and colour, so buyers want to inspect and bid lot by lot, exactly the goods that never collapsed into a single exchange grade. Many things sold this way once (tea, tobacco, furs, fish), but as products standardised they migrated to futures exchanges or to price-reporting-agency assessments, leaving the auction to the heterogeneous holdouts: wool, tea, cut flowers (the Dutch descending-clock auction), tuna at Toyosu, and dairy on the Global Dairy Trade. The trade-off is that an auction gives transparent, competitive price discovery for variable lots but offers no forward price to hedge against, so the grower carries the price risk until the hammer falls.

The animal underneath is humble economics. A prime breeding ewe is worth real money, but cull ewes and crashed markets can be almost worthless: in Australia's 2023 oversupply some sheep sold for cents or were simply given away, the grain of truth behind the "ten-dollar sheep." Sheep are sometimes called the strip-miners of pasture because they bite very close to the ground, and overstocked flocks really can scalp grass and trigger erosion, but rotational grazing, moving the flock between paddocks to let pasture recover, manages it. They are still shorn by human shearers with electric handpieces, a skilled and physically brutal trade (robotic shearing has been attempted since the 1980s but never made commercial sense), and there is a chronic shearer shortage. As for the meat, lamb is a sheep under about a year, hogget one to two, and mutton older and stronger; lamb usually costs more per kilo than beef and stays a minor meat in the United States, around a pound a head a year, for cultural and price reasons, even as it is a staple around the Mediterranean, the Middle East, and South Asia.
