US threats to seize Kharg Island, Iran's primary oil export terminal handling roughly 90 percent of its crude shipments, have shaped trader views amid the ongoing 2026 conflict over Strait of Hormuz access. President Trump stated on June 11 that US forces would take the island and related infrastructure "in the not too distant future" to control oil markets, echoing earlier March strikes on military targets there that deliberately spared oil facilities. Iran has reinforced air and naval defenses on the island in response. Recent walk-backs of planned strikes, tied to reported progress in multilateral talks, have tempered near-term expectations of a change in control, while highlighting risks of escalation or negotiated de-escalation.
