After a tropical cyclone ravaged key croplands, the market price of vanilla rose sharply in the late 1970s and remained high through the early 1980s despite the introduction of Indonesian vanilla. In the mid-1980s, the cartel that had controlled vanilla prices and distribution since its creation in 1930 disbanded. Prices dropped 70% over the next few years, to nearly US$20 per kilogram; prices rose sharply again after tropical cyclone Hudah struck Madagascar in April 2000. The cyclone, political instability, and poor weather in the third year drove vanilla prices to US$500/kg in 2004, bringing new countries into the vanilla industry. A good crop, coupled with decreased demand caused by the production of imitation vanilla, pushed the market price down to the $40/kg range in the middle of 2005. By 2010, prices were down to $20/kg. Cyclone Enawo caused a similar spike to $500/kg in 2017.
