April 13, 2026 - April 15, 2026, the price of the '5.00-5.49%' option fell from 63.05c to 47.8c, as the market saw profit-taking and a slight recalibration of expectations following the previous rapid upward adjustment.
April 11, 2026 - April 13, 2026, the price of the '5.00-5.49%' option climbed from 52.8c to 63.05c, due to heightened market concerns over Brazil's inflation outlook, with funds concentrating in this high inflation bracket.
April 13, 2026 - April 14, 2026, the price of the '4.50-4.99%' option rebounded quickly from 15.7c to 27.7c, and subsequently to 29.75c, reflecting a repricing of the likelihood of inflation settling in this range.
March 26, 2026 - March 28, 2026, the price of the '4.50-4.99%' option surged from 3.3 cents to 30.9 cents, driven by the market repricing upside inflation risks in Brazil (such as fiscal spending expectations or energy price shocks), leading to significant capital inflows into this medium-high inflation bracket.
March 24, 2026 - March 27, 2026, the price of the '3.50-3.99%' option plummeted from 20.5 cents (peaking at 30.5 cents) to 18 cents, and continued to decline to 11.5 cents subsequently, as the market abandoned its previously overly optimistic expectations of inflation cooling.
March 14, 2026 - March 15, 2026, the price of '7.00%+' anomalously surged from 1.45 cents to 15.15 cents (+13.7 cents). This spike lacks direct fundamental support (latest inflation data was a bullish 3.81%) and likely stems from a delayed, panic-driven overreaction to headlines regarding 'oil shocks,' or simply a 'fat finger' trade in an illiquid tail option.
March 13, 2026 - March 15, 2026, the '4.50-4.99%' option ticked up from 9.8 cents to 12.8 cents, reflecting slight hedging activity into higher brackets as the market digested the Daycoval report on oil price risks.
