ICSID Caseload Statistics Report Published for Fiscal Year 2026
The International Centre for Settlement of Investment Disputes published its Caseload Statistics for the 2026 Fiscal Year on 14 August 2026, recording an all-time high of 363 administered cases and 60 newly registered claims between 1 July 2025 and 30 June 2026, according to Mondaq and Herbert Smith Freehills Kramer LLP. This record volume highlights an ongoing climate of geopolitical risk, increased nationalism, and regulatory flux that drives a wedge between foreign investors and host States.
Asia-Pacific Investor Claims Maintain Steady Volume Despite Global Shifts
Investors based in the Asia-Pacific region filed nine newly registered arbitrations during fiscal year 2026, accounting for 15 percent of all new ICSID cases, according to Mondaq. This figure remains consistent with fiscal year 2025, during which regional investors brought 11 claims, representing 16 percent of the global total. Claimants in the 2026 fiscal year originated from China, Japan, Kazakhstan, and Singapore, with one proceeding featuring two co-claimants from the region. This marks a geographical concentration compared to fiscal year 2025, when claimants represented a broader array of jurisdictions including Australia, Armenia, Indonesia, South Korea, Malaysia, and the Philippines, as detailed by Herbert Smith Freehills Kramer LLP.
Global Geographic Spread and Sector Concentration of Regional Claims
Asia-Pacific investors directed their new claims against a geographically diverse group of host States in fiscal year 2026, focusing heavily on European jurisdictions. Target countries included Switzerland, the United Kingdom, Guinea, Bangladesh, Kazakhstan, Panama, and Australia. In comparison, the 2025 fiscal year saw regional investors lodge claims against South Sudan, Kazakhstan, Malaysia, Myanmar, the Philippines, Uzbekistan, France, Spain, Canada, Honduras, and Panama. Across both years, the vast majority of these disputes remained concentrated within the oil, gas, and mining sectors, alongside additional cases in construction, electric power and other energy, finance, information and communication, transportation, and services and trade.
Decline in Arbitration Cases Brought Against Asia-Pacific Host States
While regional investors stayed active abroad, new investor-State dispute settlement cases brought against governments inside the Asia-Pacific region dropped sharply. Herbert Smith Freehills Kramer LLP reported that only three new cases were registered against Asia-Pacific States—specifically Australia, Kazakhstan, and Turkmenistan—during fiscal year 2026. This represents a decline from the seven cases registered against the region in fiscal year 2025, which involved Bangladesh, Kazakhstan, Malaysia, Myanmar, the Philippines, Turkey, and Uzbekistan. Despite this drop, Asia-Pacific States continued to face a high proportion of claims from investors within their own broader region, including filings by entities from the Bahamas, China, Japan, the Netherlands, and the United Kingdom.
Reliance on Investment Treaties Over Commercial Contracts
Claimants with an Asia-Pacific connection relied exclusively on international agreements rather than direct commercial contracts to establish jurisdiction in fiscal year 2026. Mondaq noted that not a single claimant invoked a contract in their filings. Instead, investors depended principally on bilateral investment treaties and free trade agreements, supplemented to a lesser extent by domestic investment laws and multilateral treaties, mirroring a broader global reduction in contract-based claims for the period.
