El Niño and Brazil: The Economic Costs of Climate Inaction

Brazil stands on the precipice of a potential “super” El Niño, a climatic phenomenon that, while recurrent, manifests with increasing intensity, exacerbated by global climate change. Projections indicate a scenario of torrential rains in the South and severe droughts in the North and Northeast, echoing recent extreme events such as floods in Rio Grande do Sul and droughts in the Amazon and Pantanal. This erratic weather pattern poses significant challenges to macroeconomic stability, impacting everything from agricultural productivity to critical infrastructure and energy security, with potential repercussions on inflation and foreign trade.

Historically, the country's response to these events has been predominantly reactive, prioritizing post-disaster recovery over prevention. Recent data from the Federal Court of Accounts (TCU) reveals a troubling fiscal imbalance: between 2012 and 2026, spending on response and reconstruction reached R$ 21.54 billion, while investments in preventive actions totaled only R$ 6.8 billion. This resource allocation not only generates continuous fiscal pressure but also diverts capital that could be invested in productive sectors, compromising long-term economic growth and the country's resilience.

The fragility of prevention policy is multifaceted, as highlighted by the TCU. Failures in monitoring and evaluating actions, inadequate mapping of risk areas, and a high percentage of unfinished or paralyzed infrastructure projects (37%) illustrate the deficiency in risk management. Despite the promulgation of Law 14.904/2024, which requires municipalities to plan for climate adaptation, most Brazilian cities demonstrate low or very low capacity to respond to extreme events, according to the AdaptaBrasil platform. This gap in local governance amplifies economic risks, making communities and value chains even more vulnerable.

For financial markets and the business environment, the persistence of climate inaction translates into greater uncertainty and elevated costs. Sectors such as agriculture, insurance, logistics, and energy are particularly exposed to price fluctuations, supply chain disruptions, and increased premiums. Climate predictability is a crucial factor for investment planning and corporate decision-making, and its absence can affect Brazil's attractiveness for foreign capital. Building a more resilient economy requires a paradigm shift, with substantial investments in adaptive infrastructure, early warning systems, and land-use policies that consider new climate patterns.
