Kazakhstan received a $3 billion investment commitment from the International Finance Corporation for infrastructure projects, but this was overshadowed by an arbitration court's decision to dismiss $12 billion in claims against oil giants. The Permanent Court of Arbitration in The Hague ruled that Kazakhstan's claims, related to alleged costs incurred between 2011-15 in the development of the Kashagan oil field, were filed after the statute of limitations had expired. However, the court allowed another $8 billion in claims to proceed. The Kashagan field, located offshore in the Caspian Sea, is estimated to hold over 13 billion barrels of recoverable reserves and has posed significant engineering challenges due to its environment. Kazakhstan's oil production has also seen a decline, with an 8.4% drop in the first eight months of 2026 compared to the same period in 2025, partly due to disruptions on the Caspian Pipeline Consortium route.
