Market Impact

BTC-2.57%$83,421

Last Updated

O preço do Bitcoin BTC$63,636.81 tem estado estranhamente calmo por semanas, travado em uma faixa estreita abaixo de $65,000. Opções, ou contratos derivativos que oferecem seguro contra oscilações bruscas de preço, deveriam ser baratas em um mercado tão calmo. Elas não são.

Isso pode soar contra-intuitivo, mas na verdade não é, e é importante para os traders que consideram opções para se proteger contra, ou lucrar com, um potencial boom de volatilidade. A volatilidade é reversível à média e muitas vezes sobe repentinamente após um período prolongado de negociação monótona e limitada a uma faixa.

Tudo se resume ao fato de que esses contratos de opções são precificados com base no que o mercado espera que aconteça nos próximos dias ou semanas, e não no que já aconteceu recentemente.

A calma atual é real. A volatilidade realizada de 30 dias do Bitcoin, a volatilidade de preço observada nas últimas quatro semanas, caiu para uma taxa anualizada de 21.80%, a menor desde outubro de 2025. No entanto, a medida prospectiva, a volatilidade implícita ou esperada de 30 dias, representada pelo índice BVIV da Volmex, situa-se atualmente em 36%, cerca de dois terços acima da volatilidade realizada.
