Climate and Geopolitical Shocks Leave Central Banks Powerless
El Niño will add 3% to global food inflation over six to twelve months according to the European Central Bank, while attacks in the Red Sea have tripled Asia-Europe transport costs to $6,000 per container. For the first time since the 1970s, central banks face simultaneous climate and geopolitical supply shocks that their monetary tools cannot combat.
This dual pressure reveals the growing impotence of traditional monetary policies in the face of structural inflation fueled by external factors. Raising interest rates cannot stop a cyclone that destroys Brazilian crops or Houthi missiles that close the Suez Canal.
The Essentials
- El Niño could add 3% to food commodity inflation for 6 to 12 months according to the ECB
- Asia-Europe transport costs have tripled to $6,000 per container following Red Sea attacks
- Central banks maintain elevated rates despite their ineffectiveness against supply shocks
- This climate and geopolitical inflation threatens to become structural and persistent
El Niño Transforms Climate into a Permanent Inflationary Factor
The climate phenomenon El Niño, which warms equatorial Pacific waters every three to seven years, is no longer merely a meteorological hazard. It has become a macroeconomic factor that central banks now incorporate into their forecasting models.
The ECB estimates that El Niño will add 3 percentage points to global food prices over six to twelve months. This imported inflation directly hits European consumers without monetary policy being able to influence it. Raising rates will not prevent droughts in Australia from sending wheat prices soaring, nor floods in Peru from destroying quinoa plantations.
Australia illustrates this new inflationary regime. Droughts linked to El Niño reduced wheat production by 40% in 2023, sending global prices up 15% in six months. The Reserve Bank of Australia maintained its rates at 4.35% but openly acknowledges that this increase can do nothing against the weather.
The phenomenon is worsening with climate change, which intensifies the violence of El Niño episodes. The Super El Niño predicted for 2026 could be the strongest since 1997-1998, with lasting inflationary consequences that current monetary tools cannot anticipate.
Regional Conflicts Paralyze Global Supply Chains
War is transforming global economic geography into a permanent inflationary factor. Houthi attacks against merchant vessels in the Red Sea forced 90% of Europe-Asia traffic to circumnavigate Africa, extending routes by 3,400 kilometers and adding fifteen days of navigation.
This diversion has caused maritime transport costs to explode. The price of a container between Shanghai and Rotterdam rose from $2,000 to $6,000 between December 2023 and January 2024, a 200% increase in just weeks. JP Morgan Research estimates that this spike will add 0.7 percentage points to European inflation over twelve months.
Central banks find themselves powerless against this imported inflation. The European Central Bank can do nothing about Houthi missiles disrupting 12% of global maritime commerce. Raising rates in the eurozone will not influence military decisions in Sanaa.
The Ukrainian conflict amplifies this structural dynamic. Ukraine and Russia together represented 30% of global wheat exports before February 2022. Two years after the war began, cereal prices remain 25% higher than in 2021, despite agreements on export corridors.
This geopolitical inflation becomes permanent. Each new regional conflict can now jam a global supply chain and send prices soaring across entire sectors. Central banks are discovering the limits of their power in a multipolar and conflict-ridden world.
Traditional Economic Models No Longer Predict Anything
Central banks are navigating blind with instruments designed for a stable and predictable economy. Their macroeconomic models, calibrated on the post-war decades, cannot handle simultaneous climate and geopolitical shocks.
The U.S. Federal Reserve is experiencing this painfully. Its inflation forecasts for 2024 were revised upward four times between January and October, rising from 2.1% to 3.2%. Jerome Powell acknowledges that “external factors are increasingly escaping our traditional models.”
Inflation becomes multi-causal and unpredictable. A cyclone in the Philippines can send nickel prices soaring. A drought in Argentina affects global soy. A geopolitical tension at the Strait of Hormuz sends oil prices up. Central banks can no longer anticipate these cascading shocks.
This unpredictability paralyzes monetary policy. The Bank of Japan has maintained rates near zero since 2016, but Japanese inflation oscillates between -0.5% and +4% depending on climate and geopolitical hazards. The BoJ can no longer achieve its target of stable 2% inflation.
Economists acknowledge this failure of models. The OECD has abandoned its two-year inflation forecasts, deemed “too uncertain in the current context.” The IMF now revises its projections every three months instead of twice a year.
The Monetary Weapon Dulls Against Persistent Supply Shocks
Central banks maintain elevated rates out of habit more than effectiveness. The European Central Bank raised its rates to 4%, their highest level since 2001, but acknowledges that this increase does not combat climate and geopolitical inflation.
This impotence is measured in the numbers. Despite policy rates at 5.5% in the United States, American food inflation remains stuck at 3.8% for eight months. The Fed can do nothing about California droughts sending fresh vegetable prices skyward.
Europe is experiencing the same failure. The ECB’s deposit rate rose from -0.5% in 2022 to a peak of 4% in 2023, a 4.5 percentage point increase. Yet European energy inflation oscillates between 8% and 15% depending on geopolitical tensions and climate hazards, with no correlation to monetary policy.
Central banks are discovering that raising rates can even worsen supply inflation. High rates increase the cost of investments in renewable energy and transport infrastructure, slowing the transition toward an economy less dependent on external shocks.
This contradiction forces a doctrinal revision. Sweden’s central bank was the first to cut rates in December 2024 despite inflation at 4%, acknowledging that “monetary policy cannot do much against imported inflation.”
Central Banks Attempt New Anti-Inflation Tools
Facing this impotence, some central banks are experimenting with unconventional instruments. Chile’s central bank created in 2024 a “climate corridor” that adjusts rates according to the intensity of weather shocks. Rates automatically decline in the case of major droughts or floods.
This innovation remains marginal but inspires other emerging countries. Brazil has been testing since January 2025 “climate swaps” that allow agricultural businesses to hedge against weather hazards directly with the central bank. The objective: limit the transmission of climate inflation to the rest of the economy.
Central banks in developed countries remain more conservative but are evolving. The Reserve Bank of Australia has incorporated El Niño weather forecasts into its monetary policy models since 2024. A global first that is inspiring the U.S. Federal Reserve.
Europe is seeking its path between orthodoxy and pragmatism. The ECB is studying the creation of a “climate stabilization fund” that would intervene in commodity markets in the event of a major weather shock. The idea divides the governing council between orthodox Germans and pragmatic Southern Europeans.
These experiments remain timid in the face of the challenge’s scale. Tariffs and commercial sanctions add a third source of structural inflation that monetary tools cannot combat.
Central banks are navigating toward a world where their traditional instruments become secondary to climate and geopolitical forces. They must either accept their impotence or invent monetary policy for the era of permanent shocks.
