Asbestos: Cycles
A fifty-year collapse instead of booms and busts
What this tab covers Price history and what drives booms and busts, including this commodity's super-cycles, the drivers behind them and the metrics to track. It charts monthly prices (World Bank) with a switch to inflation-adjusted annual prices; where there is no World Bank series it uses USGS US prices.Asbestos has a long structural decline, not a price cycle. US consumption peaked at 803,000 t in 1973 and fell to 50 t in 2025. World use fell from about 2 million t in 2000 to an estimated 930,000 t in 2025, a drop of nearly 55%. Tilton and Guzman use asbestos, like lead, to show how health regulation can permanently shrink demand. The last US price, an import unit value, rose from $1,880 per tonne in 2021 to $2,630 in 2022. Imports then stopped, so no later price exists.

Asbestos shows a long rise and a slow structural collapse, not a super-cycle. It was a cheap wonder fibre for most of the 20th century. Health evidence and liability then drove bans: US use peaked at 803,000 t in 1973 and is now near zero. World use halved between 2000 and 2025, and the remaining demand sits in Asian asbestos-cement products. Prices are not published as a series. Customs unit values show spikes when sanctions and logistics squeeze supply, as in 2022.
- 1973-2018
Health and liability issues pushed asbestos out of US markets, product by product, as substitutes took over.
US consumption 803,000 t (1973) to 500 t or less every year since 2018 (USGS); no long price series published.
- 2000-2025
Bans spread (EU-wide from 2005, Brazil's Supreme Court ruling of 2017, upheld 2023), and world fibre use more than halved.
World consumption about 2 Mt (2000) to 930,000 t (2025) (USGS); India's import unit value about Rs 34,400/t (2019-20) to Rs 38,400/t (2020-21) (IBM, derived).
- 2022
Sanctions on Russia and transport disruption backed up exports; Kostanay Minerals paused mining on 1-10 May 2022 because its warehouses were full.
US import unit value rose from $1,880/t (2021) to $2,630/t (2022), up 40% (USGS).
- 2024-2037
The US EPA banned chrysotile in March 2024; imports of fibre stopped in May 2024 and chloralkali use must end by 2029-2036, with sheet gaskets last in 2037.
US consumption 115 t (2024) to 50 t (2025), drawn from stockpiles (USGS).
What drives the cycle
- National bans and court rulings. Each ban removes a market permanently; Brazil's phase-out would take out about 15% of world supply.
- Low-cost housing in Asia. Asbestos-cement roofing remains the main use where price outweighs health concerns.
- Sanctions and transport routes. Russia and Kazakhstan supply most fibre; rail and port disruption can strand exports.
- Cost of substitute fibres. Cellulose and synthetic fibre-cement must get closer to asbestos-cement cost to replace it.
- Litigation. Liability costs deter users and investors; US deadlines may still change after 2025 legal proceedings (USGS).
