Episode: "Is there really $500bn of Rare Earths in Ukraine?"

Date: March 8, 2025
Host: Tim Harford (BBC Radio 4)
Guest: Eli Sakhlatvala (Head of Non-Ferrous Metal Pricing, Argus Media)

Overview

In this episode, Tim Harford investigates recent claims circulating in the news that the US could secure "$500 billion worth of rare earths" from Ukraine. With expert insight from Eli Sakhlatvala of Argus Media, the show disentangles definitions, scrutinizes the credibility of mineral valuation estimates, and clarifies the real stakes in rare earth and critical minerals supply chains, particularly in the context of geopolitical tensions and the energy transition.

Key Discussion Points & Insights

1. What Are Rare Earths? (01:38–03:11)

• Definition Misconceptions: The term "rare earths" is often confused with broader mineral wealth.
• Scientific Clarification: Rare earths are 17 specific elements, as humorously listed in a Tom Lehrer-style musical nod by Helen Arney.
  • Notable Moment: Helen Arney's song naming all 17 rare earths (02:14).
  • Use Cases: Glassmaking, ceramics, catalysts, magnets for electric vehicles, and wind turbines.

Quote (02:33):
Tim Harford: "That was geeky songstress Helen Arney listing all 17 rare earths, with apologies to the great Tom Lehrer."

2. Are Rare Earths Really Rare? (03:11–04:53)

• Abundance in Nature: Despite their name, rare earths are not actually "rare" in Earth's crust.
  • Quote (03:11):
    Eli Sakhlatvala: "They are famously not rare...They are quite abundant in the Earth’s crust."
• Extraction Challenges: Access, extraction, and processing make them ‘rare’ in supply chains.
  • Geological complexity: Often found mixed with radioactive elements like uranium and thorium.
  • High CAPEX and timelines: Starting a new project can take over a decade and cost more than $1 billion, with no guaranteed pricing power due to China’s market dominance.

Quote (03:32):
Eli Sakhlatvala: "Within the metals world, it's a bit of an in joke that rare earths are not really rare."

3. Geopolitical Stakes & the US-Ukraine Narrative (05:07–05:53)

• US Dependency on China: The US is highly reliant on Chinese rare earths, heightening strategic concerns.
• Vulnerability Illustrated: COVID-19 exposed the dangers of overreliance on a single source for critical materials.

Quote (05:15):
Eli Sakhlatvala: "These are undoubtedly critical materials for all sorts of industries...the US supply chain...is extremely vulnerable."

4. The $500 Billion Claim – Does It Add Up? (05:53–09:18)

• Dubious Figures: The claim that Ukraine holds $500bn in rare earths does not align with market realities.
  • Ukraine’s actual reserves of true rare earths are only loosely mapped (mostly with outdated Soviet-era surveys).
• Market Comparison:
  • The global rare earths market was about $12.4 billion in 2024, making a $500bn valuation implausible.
    • Quote (07:00):
      Tim Harford: "That would be the value of the entire global market. For decades."
    • Quote (08:11):
      Eli Sakhlatvala: "It would be an extraordinary amount. If we're talking about true...rare earth elements."
• Likely Explanation:
  • The term "rare earths" is being stretched; more likely, it conflates a variety of valuable minerals—lithium, titanium, graphite, manganese, and others—all present in Ukraine.
  • Quote (08:28):
    Eli Sakhlatvala: "The term rare earths is being used in quite a loose sense to refer to this wide array of minerals..."

5. How Much Are Ukraine’s Mineral Resources Worth? (09:14–09:50)

• Numbers with a Grain of Salt: Cited numbers (e.g., $15 trillion) are mostly speculative and depend on extraction feasibility, not just presence in the ground.
  • Many such figures are best treated with skepticism until modern exploration and valuation are done.
  • Quote (09:50):
    Eli Sakhlatvala: "It's always very, very difficult to estimate the value of resources in the ground...I would take them with an enormous pinch of salt."

Tone & Style

The episode is characteristically skeptical, data-driven, and wry, with a debunking spirit. Tim Harford’s hosting remains genial and probing, while Eli Sakhlatvala provides grounded, industry-insider clarity on technical topics.

Summary

The claim of "$500 billion worth of rare earths in Ukraine" is highly dubious when compared to both the actual global market value of rare earths and the technical difficulties in extracting and commercializing such resources. The real mineral wealth of Ukraine is broader, involving many critical minerals vital for the green energy transition, but breathless figures in headlines should be treated critically—especially when they rely on outdated surveys and imprecise definitions.

This episode is an accessible and illuminating case study of how numbers in the news—especially as they relate to geo-economics—require careful scrutiny before being accepted at face value.
