The convergence of two major economic headwinds—a strengthening El Niño weather pattern and rising energy prices stemming from Middle East geopolitical tensions—could derail inflation's recent downward trajectory, according to a Friday analysis from JPMorgan. The investment bank projects that the combination could increase global headline inflation by roughly 0.3 percentage points in 2024, reversing months of progress central banks have made in cooling price pressures.
JPMorgan estimates an 81% probability that the current El Niño event will intensify into a "very strong" or "super" classification by year-end, with a 97% likelihood that such conditions will persist through the forecast period. Historically, powerful El Niño episodes have disrupted agricultural output and commodity supply chains, creating upward pressure on prices across food and energy sectors.
The timing of these dual shocks—weather-driven supply constraints colliding with geopolitical-driven energy costs—presents a particular challenge for policymakers who have spent the past two years wrestling inflation back toward target levels. If both scenarios materialize as JPMorgan projects, central banks may face renewed pressure to maintain elevated interest rates longer than previously anticipated, potentially complicating economic growth prospects heading into 2024.
