When Iran closed the strait of Hormuz the debate focused on oil prices and petrol pumps. Our VoxEU column with @alvinulido, S. Mouabbi & @Adrien_Rousset shows that effective economic policy must consider broader supply chain dynamics following supply bottlenecks 👇

12/13 Our framework provides policymakers and market participants a new lens to understand commodity market disruptions and their heterogeneous global impacts.

11/13 Was the COVID supply chain experience exceptional? Our work shows diverse commodity disruptions systematically shape macro outcomes—COVID-19 was just part of a broader pattern.

10/13 For central banks: this means different policy responses required depending on your country's commodity position. One-size-fits-all tightening could exacerbate output losses for net importers.

9/13 Net exporters are partially insulated, able to offset higher import costs with commodity revenue gains. The following four figures show the response of industrial production on oil supply (top row) and non-oil supply disturbances (bottom row) across commodity importing and exporting countries.

8/13 Net importers of both oil and non-oil commodities (think most European and Asian nations) face a double whammy: stronger inflation pass-through and more persistent output contractions.

7/13 To illustrate: consider the response of inflation to a negative commodity supply development driven by geopolitical risk. The following four figures show the response of inflation on oil (top row) and non-oil supply disturbances (bottom row) across commodity importing and exporting countries.

6/13 Relevant *right now*: the response of inflation and output to supply-side shocks driven by geopolitical risk dominates. For a potential conflict escalation, this means: initial inflation spikes across most economies, but the effects differ dramatically between net importers vs. exporters.

5/13 Our most striking finding is that supply disturbances in non-oil commodities (natural gas, metals, grains, etc.) affect inflation and industrial production at least as strongly as oil. The literature's narrow focus has severely understated commodity shocks' importance.

4/13 Our innovation: automated narrative analysis to create daily supply and demand proxies of shocks for 20 commodities. We further decompose commodity fluctuations into key drivers including geopolitical risk, natural disasters, and climate change.

3/13 Why? Because modern economies depend on a much broader commodity basket. The COVID-19 pandemic, Ukraine, and current geopolitical tensions make this gap impossible to ignore.

2/13 Our @cepr.org WP "Beyond Oil: The Origins of Commodity Price Fluctuations", with Alvin Lumbanraja, Sarah Mouabbi and Adrien Rousset Planat, analyzes 1.1 million news articles to build the first comprehensive framework measuring supply/demand disturbances across the entire commodity space.

1/13 As Middle East tensions escalate, markets are fixated on oil prices. But our new research suggests the economic fallout from Iran conflict goes way beyond oil as the Strait of Hormuz—a critical shipping chokepoint—remains closed, with some countries facing much harder recoveries than others.

US Firms Are Snapping Up the Rare Earths Europe Needs to Rearm As Europe embarks on a historic rearming effort, its defense companies are scrambling for a vital component in high-tech weapons: rare earth minerals, which more nimble US rivals are scooping up.

More rare earths depression for Europe. It's too slow so US rivals getting supplies first

“If we look at how long it takes us on average to sell, say, a ton of terbium to a European partner, we’re talking 3-4 weeks; with the Americans it’s more 3-4 days"

Graph showing net demand indices and the business cycle. Commodity prices have historically been considered leading indicators of inflation, but the relationship has weakened since the mid-1980s, making them less reliable predictors. This column analyses more than a million Reuters news articles between 2001 and 2023 to capture supply and demand dynamics in commodity markets. The findings show that text-based indicators of supply and demand disturbances significantly enhance inflation forecasting accuracy, allowing policymakers to better understand the nature of inflationary pressures and adjust their responses accordingly.

In 2014, half of Greece's electricity was generated by coal.

A decade later, that share has fallen to just 6%.

China’s rare earths controls prompt fears of auto shortages and shutdowns Traders and executives warn of limited inventories and a risk of disruption to automotive production

A senior automotive executive described China’s latest export controls on rare earth minerals as a 7 or 8 on a scale of 1 to 10 in terms of severity.

China Halts Critical Rare Earth Exports as Trade War Intensifies (Gift Article) Beijing has suspended exports of certain rare earth minerals and magnets that are crucial for the world’s car, semiconductor and aerospace industries.

It's kind of telling that Trump thought he was punishing China by making it prohibitively expensive for American manufacturers to buy critically important inputs, and China countered by making it impossible for American manufacturers to buy critically important inputs
