Chile’s Kast Names Fontaine to Chair the World’s Top Copper Producer
Key Facts
—The appointment: Chilean President José Antonio Kast designated economist Bernardo Fontaine as the new chairman of Codelco, the world’s largest copper producer. Fontaine takes office on May 26, replacing Máximo Pacheco.
—The board reset: Kast also named Luz Granier and Alejandro Canut de Bon as new board directors. The three replace Pacheco, Josefina Montenegro, and Alejandra Wood. Appointments run for four-year terms.
—The crisis: A Codelco internal audit found that 20,000 tonnes were inappropriately added to December 2025 production figures, allowing the company to formally meet annual targets. External investigations are now under way.
—The financial picture: Codelco transferred $7 billion to the Chilean state over the past four years while debt grew by more than that figure, in Fontaine’s own diagnosis. He described the company as “carrying a lead backpack” and pledged public-private partnerships as a structural fix.
—The political signal: Fontaine was a close adviser to Kast’s 2025 campaign and a former constitutional convention member. His appointment marks the most visible signal yet of the Kast administration’s shift toward market-friendly governance at the state copper company.

Chile’s new right-wing administration just put its closest economic adviser at the head of the world’s largest copper company, in the middle of an accounting scandal. The signal for the global copper market is unambiguous: Codelco is being reset, the public-private model is opening, and the people who shaped Kast’s first 90 days are now responsible for the cash machine that funds the Chilean state.
Who is Bernardo Fontaine?
Fontaine is an economist trained at the Pontificia Universidad Católica de Chile, with more than three decades in business and advisory roles. He has served as director of more than 20 Chilean companies across financial services, retail, logistics, real estate, insurance, and public services, including Falabella, Banco Bice, and Metro de Santiago. He was a member of the 2022 Constitutional Convention and became one of the visible faces of the “Con mi plata no” movement defending individual ownership of pension funds. He is the brother of former minister Juan Andrés Fontaine. The Rio Times, the Latin American financial news outlet, reports that the new chairman is widely read as a market-friendly appointment with deep ties to Kast’s economic team.
Fontaine was reportedly the figure who introduced Kast to economist Jorge Quiroz in early 2025, helping shape what became the Kast economic platform. He declined to take a ministerial role but participated in designing the first 90 days of the new administration. His arrival at Codelco follows months of speculation about the leadership reset and several weeks of public criticism of incumbent chairman Pacheco’s management.
Why does the timing matter?
The announcement landed in the middle of a Codelco production-accounting scandal. A preliminary internal audit found that roughly 20,000 tonnes were added to December 2025 production figures, allowing the company to meet its annual target. Joint Minister of Economy and Mining Daniel Mas confirmed that investigations and possible external audits are being launched. “The new directors will take office with a special mandate of investigation and possible external audit, to recover the information Chileans deserve to know,” Mas said.
Mas described the broader inheritance as a company facing “production figures currently under audit” and “economic performance that leaves much to be desired.” The Kast administration’s framing positions the new board as a reset team rather than a continuity team. Granier brings infrastructure and energy directorship experience including Colbún, Metro de Santiago, Entel, and Saesa, plus a public-sector record as a former deputy minister. Canut de Bon brings mining-law specialisation, having served as director of state mining company Enami and legal counsel for BHP at Minera Escondida and JX Mining at Caserones.
What does this mean for Codelco’s strategy?
Fontaine published a public statement after his appointment listing the structural challenges: rising costs, high debt, declining production, “serious problems in the structural investment projects,” worker safety, global sustainability, and the need to deepen public-private partnerships. He framed the financial picture in stark terms: “Codelco delivered $7 billion to the State over the past 4 years while its debt grew by more than that figure. In other words, the entire State contribution was pure debt.”
Mas was explicit about the public-private opening: “For Chile to be a true mining power, Codelco must establish alliances, understanding the relevance that work with the private sector has for the future of the company.” This is a structural break from the previous Boric administration’s posture, which prioritised state-led restructuring including the lithium partnership with SQM. The new framework opens the door to private-sector participation in Codelco’s largest structural projects, including Chuquicamata’s underground transition and El Teniente’s New Mine Level.
Codelco’s challenges at a glance
| Indicator | Reading |
|---|---|
| State transfers (past 4 years) | ~$7 billion |
| Net debt increase (same period) | More than $7 billion |
| December 2025 audit issue | 20,000 tonnes added to production figures |
| Production status | Under formal audit |
| Structural projects flagged | Multiple budget overruns |
| New chairman effective date | May 26, 2026 |
| Board terms | 4 years |
| Public-private partnership posture | Explicitly opened |
Finance Minister Jorge Quiroz described Fontaine’s appointment as a “first line” pick to address inherited problems. The market reading is that Kast is signalling seriousness on both the production audit and the structural turnaround. Codelco’s bond spreads have been the most direct external signal of investor sentiment; subsequent issuances will test whether the board reshuffle materially shifts cost of capital.
What should investors and analysts watch next?
- External audit findings. Independent confirmation of the 20,000-tonne December issue, plus any wider production-restatement, will reset the baseline for future quarterly comparisons.
- Public-private partnership announcements. Any framework agreement on Chuquicamata Underground, El Teniente New Mine Level, or Andina expansion would be a structural signal to the global copper market.
- Bond market response. Spread compression or widening on Codelco’s outstanding USD curve will be the cleanest external read on whether the board reset shifts credit quality perception.
- Lithium and Boric-era partnerships. Whether the SQM-Codelco lithium framework survives the new administration is an open question with material implications for global lithium supply.
- Copper price backdrop. Copper at $6.57/lb provides decent operating cash flow if Codelco can stabilise volumes. A price reversal during the turnaround would compress execution room.
Frequently Asked Questions
Is Codelco being privatised?
No. Codelco remains 100% state-owned by constitutional mandate. The Kast administration is opening public-private partnerships on specific projects rather than transferring company ownership. Any deeper change would require a constitutional amendment.
What is the production-audit scandal?
A preliminary internal audit found that approximately 20,000 tonnes were added to December 2025 production figures, allowing Codelco to meet its annual target. Executives reportedly invoked an internal norm permitting the addition. The new board has been mandated to commission external audits and clarify the methodology.
How does this compare to past leadership transitions?
Codelco chairs typically reflect the political colour of the incumbent administration. Pacheco was a Boric-era appointment. Fontaine’s arrival is comparable in scale of political shift to past transitions, but the combination of audit scandal, debt diagnosis, and PPP opening makes this reset more structural than past changes of guard.
