The measure was publicly announced by Iranian officials in early September 2026.
An Iranian exclusion/restricted zone that raises tanker and insurance risk can push global freight and crude costs higher. That generally pressures spreads on shorter-dated, oil-importer sovereign bonds (near-term eurobonds and belly maturities) while potentially supporting longer-dated bonds of African oil exporters via improved revenue visibility, though actual spread moves depend on shipping disruptions, spare capacity and global risk sentiment.
