What was the Ley Reservada del Cobre (Reserved Copper Law)?
A 1958 Chilean law requiring Codelco (state copper company) to transfer 10% of copper-export revenues to the armed forces for weapons procurement — roughly one quarter of the total military budget at copper price peaks. The law was secret ("reservada"); spending was not subject to normal congressional oversight. It was repealed in 2019 and replaced by the Strategic Capabilities Fund, with the transition to fully parliamentary-appropriated defense spending completing by 2029.
