Water Futures Climb as Traders Price a Long, Dry Autumn

GENEVA — The loudest number on the Cerulean Exchange this week was not a stock but a liter. Contracts for delivered fresh water firmed again as traders priced in a dry autumn across three water-stressed megacities, extending a climb that has made desalination capacity the exchange's most closely tracked asset. "People still call it a commodity," said floor analyst Priya Deshmukh. "It stopped being one when you can't substitute it." The pressure runs back to households: in Jakarta, utility clerk Sari Wibowo says her district's tariff has risen twice since June, each increase traceable to the same delivered-water cost the traders in Geneva quote by the second. The exchange sees the tightening as orderly for now, not a shock. But with registered climate migrants approaching 116 million and swelling the demand on stressed corridors, analysts warn the arithmetic gets harder before it gets easier. The screens count in cents. Wibowo's neighbors count in buckets.
