Why Is Oud So Expensive? The Truth Behind the World’s Most Valuable Fragrance

Few materials in the world command the reverence — and the price tag — of oud. Gram for gram, fine oud oil can exceed the value of gold. But what exactly makes this ancient resin so extraordinarily costly, and why has it captivated civilisations for thousands of years?

Known across the Arab world as oudh, and throughout Southeast Asia as agarwood, oud is the dark, fragrant resinous heartwood that forms inside Aquilaria trees when they become infected with a specific mould.

The result is one of nature’s most complex and intoxicating aromatic substances – and one of the most expensive raw materials on earth. Understanding its price requires understanding its entire journey, from deep in the forest to the skin.

If you have been asking “why is oud so expensive?” – this guide covers everything: the biology, the economics, the market, and how to find authentic oud oil in Australia without being misled.

A brief history: oud through the ages

Oud is not a modern luxury invention. Its use stretches back at least three millennia. Ancient Sanskrit texts reference agarwood as a sacred substance used in religious ceremony. The Bible and the Quran both mention aloes wood – widely believed to be agarwood – as among the most precious of aromatic gifts. In imperial China, it was burned in royal courts and Buddhist temples alike. In Japan, the practice of kōdō — the art of listening to incense — was built largely around the subtleties of agarwood.

In the Arabian Peninsula, oud became inseparable from culture and identity. Burning bakhoor before guests, anointing the body with oud oil before prayer and celebration, gifting fine oud as a mark of deep respect – these traditions persist to this day. The recent explosion of oud fragrance in Western fine perfumery – with houses like Tom Ford, Maison Francis Kurkdjian, and Dior releasing landmark oud compositions – has introduced an entirely new audience to the material, creating global demand that a scarce natural supply chain struggles to meet.

A rarity born from suffering

The story of oud wood begins with a tree in distress. The Aquilaria genus, native to the rainforests of South and Southeast Asia — spanning India, Bangladesh, Cambodia, Vietnam, Malaysia, Indonesia, and beyond — only produces its prized resin as a defence response to fungal infection, primarily Phialophora parasitica. When the fungus penetrates the sapwood, the tree responds by flooding the affected area with a dark, oleoresinous compound. Over years and decades, this saturates the heartwood, turning pale timber into the dense, dark, fragrant agarwood we prize so highly.

Here is the unsettling truth: only about 2% of wild Aquilaria trees ever become infected naturally. Centuries of over-harvesting, combined with the clearing of Southeast Asian rainforests, have pushed multiple Aquilaria species onto CITES protected lists. Wild oud is increasingly rare, legally restricted, and in some origins, essentially exhausted — a key driver of why oud oil price continues to rise.

“Oud is not simply an ingredient. It is a living record of time, ecology, and transformation — irreplaceable in every sense.”

The 7 reasons oud commands such a price

So why is oud so expensive?

There is no single answer – it is a convergence of seven compounding factors, each of which would make any ingredient costly.

Together, they explain why the finest pure oud oil commands prices that exceed precious metals.

• Extreme natural scarcity
  Wild Aquilaria trees that yield harvestable resin are genuinely rare – only about 2% of trees are affected. Decades of unregulated logging have depleted populations across India, Bangladesh, Cambodia, and Indonesia. What remains is heavily protected and legally restricted under CITES international trade laws.
  
• Decades of maturation
  Premium oud resin develops slowly – the most sought-after grades come from trees harbouring infection for 40 to 100 years. An oud from a century-old infected tree is as much an heirloom as a fragrance ingredient. This time investment cannot be shortcut or scaled.
  
• Extraordinarily low distillation yield
  It takes hundreds of kilograms of agarwood chips to distil a single kilogram of pure oud oil – a yield rate often below 0.5%. Every millilitre of genuine oud represents a significant quantity of raw material consumed in the distillation process.
  
• Skilled, labour-intensive harvesting
  Identifying infected trees deep in dense forest, carefully extracting resin-bearing heartwood, and hand-sorting wood chips by resin density demands years of expertise. The entire supply chain from forest to distillery is deeply, irreducibly human – and cannot be mechanised.
  
• Distillation artistry
  Traditional oud distillation is as much craft as chemistry. Master distillers spend years mastering the precise temperature, pressure, duration, and water quality needed to coax the finest oil from the wood. A poorly distilled batch can destroy the olfactory complexity that defines exceptional oud.
  
• Geographic variation and terroir
  Like fine wine, oud expresses its origin with remarkable fidelity. Hindi oud is earthy and animalic; Cambodian oud is sweeter and fruitier; Malaysian oud is clean and green; Vietnamese oud is often creamy and floral. Provenance profoundly shapes value – and certain classic origins are commercially exhausted.
  
• Surging global luxury demand
  Oud has crossed from Arabian Gulf culture into the most prestigious Western fragrance houses. This convergence of deep-rooted Eastern tradition and rapidly growing Western luxury appetite has created a demand spike that the natural supply chain – already under severe ecological pressure – simply cannot meet.

Cultivated Oud (Oudh): a sustainable answer

Recognising the ecological crisis in wild forests, producers in Vietnam, Malaysia, Thailand, India, and increasingly Australia have pioneered plantation cultivation of Aquilaria trees with artificially induced infection.

This cultivated agarwood oil – sometimes called farmed oud – has allowed the fragrance world to continue without stripping the last wild forests bare.

The debate between wild and cultivated is real. Wild oud develops an aromatic complexity shaped by decades of environmental variables that plantations cannot fully replicate.

And yet: the finest cultivated oils – particularly Vietnamese plantation oud – are genuinely extraordinary. More importantly, cultivated oud is the ethical choice, and increasingly the only responsible choice available at scale.

Australia has quietly emerged as a significant contributor to cultivated agarwood production. Aquilaria trees thrive in tropical Queensland and the Northern Territory, and Australian-grown agarwood is earning recognition for its distinctive clean, soft profile with a subtle sweetness that resonates with contemporary Western fragrance sensibilities.

This makes Australia not just a consumer of oud culture, but a genuine contributor to its sustainable future.
