The world economy may have dramatically dipped and the price of oil crashed, but one commodity is seeing an unprecedented boom: the face mask. Samanth Subramanian explores the newly distorted marketplace for masks and the lengths some will go to get them
When the coronavirus began spreading beyond China in January, the race to buy up any available protective face masks went global. It caused a frenzy of buying as prices rocketed and suppliers were overwhelmed by the demand.

For one man, Ovidiu Olea, a businessman in Hong Kong, it was the start of a wild ride from mask buyer to mask dealer to ultimately, mask producer. The Guardian writer Samanth Subramanian caught up with him as he begins production. He tells Rachel Humphreys about how distortions in the mask market have led to diplomatic incidents.

But with mask sales rocketing and many governments starting to either recommend or insist on their use, the evidence about their efficacy is still inconclusive. And some fear that widespread rush to buy up stocks will prevent them reaching the people who need them most: frontline workers and medics.
