Quando a paz chega ao Oriente Médio, nem sempre chega da forma que os mercados esperavam. O acordo de cessar-fogo entre Estados Unidos e Irã, anunciado por Donald Trump, reabriu o Estreito de Ormuz e derrubou o petróleo quase 5% — e com ele, as ações da Petrobras, que sozinhas carregam 12% do Ibovespa. O índice, que subia mais de 1% pela manhã, fechou em queda de 0,35%, lembrando que o alívio geopolítico e o alívio financeiro nem sempre coincidem.

US-Iran diplomatic rapprochement signals potential de-escalation in Middle East tensions, reducing US regional military posture. Iran gains legitimacy through peace agreement. Global energy markets shift from conflict-premium pricing to normalized supply expectations, benefiting oil-importing nations but pressuring commodity-dependent exporters like Brazil.
Similar to 2015 Iran nuclear deal (JCPOA) which initially caused oil price declines and benefited global markets, though geopolitical risk premiums returned when US withdrew in 2018.

Inflation-sensitive sectors
Lower oil prices benefit consumers through reduced fuel and transportation costs, but Ibovespa decline may reduce household wealth and investment returns. Potential monetary policy easing could support consumption, though inflation pressures remain.
Central Bank may proceed with Selic rate cuts as geopolitical risk premium diminishes, but must balance this against persistent inflation core pressures and resilient economic activity. Policy pause may follow initial cuts to assess lagged effects of stimulus.
