Recent SP drop most likely due to the political instability in Chile.
The lefty dominated assembly approved a proposal to nationalise copper and lithium mines.
Even if these radical measures do make their way into drafting in the next few weeks they are still required to have majority support in the referendum later this year. This means that they will draft a document that is likely to be supported by a broader base ie. more lenient
Note that Boric appointed a centrist central bank boss as finance minister, potentially showing he is willing to compromise.
Most importantly, if Chile wanted to nationalise all these copper and lithium projects they would have to spend billions of dollars in compensation. This would reduce their ability to spend on welfare and social expenditure, which is a key issue in his campaign.
As a previous poster alluded to, I think it is more likely that Chile reaps the benefits through higher taxation of foreign investment in these mines.
