How a pig’s tusks became a measure of wealth
In parts of Vanuatu, especially on the island of Malekula, pigs have served as important forms of wealth in systems of exchange. Their value could be judged by their tusks: a pig whose upper tusks curled into a near-complete circle was far more prized than one with ordinary tusks.
The curl was produced through careful husbandry. A pig’s lower tusks were removed or broken so they could not wear down the upper pair. Left to grow, the upper tusks curved inward over time. The result was a living asset whose value depended partly on years of care—and on a feature that could be seen and compared.
Wealth that had to be kept alive
A tusked pig was not simply money in animal form. Pigs could be exchanged in major social transactions, including marriage arrangements, compensation, and ceremonies. Giving one away could help establish or honor relationships; possessing prized pigs could signal status and the ability to meet obligations.
That made wealth demanding to hold. A pig needed food and protection, and its tusks could be damaged before they reached the desired shape. Its owner also had to weigh the value of keeping it against the purposes for which it might be given or killed. The asset could grow more valuable with time, but only if it survived—and only if its owner could eventually put it to social use.
From animal to public value
At a gathering, a pig could be killed and shared, turning stored wealth into a visible act of generosity and exchange. The value did not vanish; it changed form, helping create or reinforce ties among people. A living pig could therefore represent both accumulated resources and future obligations.
That is the striking economic logic: the tusks measured more than an animal’s rarity. They embodied years of labor and care, while the pig’s eventual exchange or feast made that investment matter to a wider community.
