Analysis

5d ago

This market shows extreme mispricing with the "Yes" position (no rate change) trading at just 4¢ despite historical precedent suggesting rate holds are plausible outcomes for the Brazilian central bank. The implied yield of 75,122% on the Yes side is extraordinarily high and likely reflects illiquidity rather than genuine probability—the $16,480 open interest is modest for such a volatile contract, and the 1¢ spread is tight relative to the price level. The sharp 55% price collapse over seven days (9¢ to 4¢) combined with only 12 days to expiry and a cliff risk index of 24 suggests either informed traders are heavily betting on a rate change, or the market is simply too thin to price accurately.
