Japan Meteorological Agency Declares El Niño Onset, Intensifying Food Inflation Pressures
Alina Collins
Japan's JMA became the first major weather agency to declare El Niño's return after three years; some forecasters expect record-breaking intensity. Thai white rice surged 20% in May — the biggest monthly jump since 2008 — signaling acute food-inflation risk for the second half.
Who called it first, and why does this one stand out?
Japan Meteorological Agency (JMA) is the first major weather body to officially declare El Niño has begun.
Bloomberg commodities columnist Javier Blas noted this is the first El Niño in three years; some forecasters expect it could reach record-breaking intensity.
This means → if those intensity forecasts hold, this is not a routine climate swing — it could reshape global agricultural supply on a historic scale.
What exactly is El Niño, and how is strength measured?
El Niño — abnormal warming of equatorial Pacific waters that shifts rainfall and temperature patterns worldwide — is classified by NOAA using the Niño 3.4 sea-surface temperature index.
Thresholds: five overlapping three-month periods ≥ 0.5 °C above the long-term mean = El Niño; ≥ 1.5 °C = strong; ≥ 2 °C = very strong.
In plain terms = the hotter that stretch of ocean gets, the more global weather is disrupted — and this time, it may reach a historic extreme.
Are food prices already reacting?
Thai white rice — the Asian regional benchmark — surged 20% in May alone, the largest single-month gain on record since 2008.
Global grain prices posted their biggest monthly rise since 2008 over the same period.
This means → markets are not waiting for El Niño to hit full force; capital is front-running the supply shock — fear of crop losses is running ahead of actual losses.
Which regions face drought, and which face flooding?
Hotter and drier: Australia, Southeast Asia, the northern U.S. and Canada — higher risk of drought and wildfire.
Wetter than normal: the southern U.S., Chile, Argentina, and parts of East Africa.
India's monsoon rains have already been delayed; Peru's fishing season is disrupted — this reflects early-stage impacts already materializing, not just forecasts.
What is the key variable to watch in the second half?
The central question: whether this El Niño escalates to a very strong event, and how severely it hits the world's major farming regions.
Scientists expect heat released from the Pacific to push global temperatures higher still; 2027 could rank among the hottest years on record.
In plain terms = how far food prices rise depends on how fierce this El Niño ultimately becomes — and that answer won't arrive until the second half of the year.
