Geopolitics Daily Brief — June 23, 2026

1. Iran oil waiver lowers the Hormuz premium, but not the sanctions risk

• The U.S. Treasury issued a temporary general license allowing the production, delivery and sale of Iranian crude, petroleum and petrochemical products through August 21, with related banking, insurance and transport services covered under the framework Reuters described.1
• Washington says the license follows Iranian commitments on IAEA access and free transit through the Strait of Hormuz; Iran has publicly disputed that new nuclear commitments were made in the Switzerland talks.2
• Tanker traffic through Hormuz began to recover on Monday, and oil’s war premium eased: Reuters reported Brent down 1.22% to $76.95 early Tuesday after prices settled more than 3% lower in the prior session.3

2. Lebanon quiets, but the ceasefire channel is still politically exposed

• Under the same regional framework, officials reported a sustained lull in Lebanon after Israel agreed a new ceasefire on Friday; Lebanese officials said intense fighting continued for another day but had abated since Saturday night.2
• A hospital director in Nabatieh told Reuters by phone that it was the first two full days of calm since the war began and the longest ceasefire he had seen.2
• Israel and Lebanon were due to start a new round of talks in Washington on Tuesday, while Iran’s foreign ministry said final Lebanon arrangements could be reached in coming days.5

3. China turns rare-earth supply into a targeted export-control tool

• China added MP Materials, USA Rare Earth and eight other U.S. entities it linked to the U.S. military to its export-control list, in retaliation for Washington’s new restrictions on Chinese companies.6
• Beijing said organizations and individuals in any country are prohibited from transferring or supplying China-origin dual-use items to the named entities, turning prior licensing hurdles into a full ban for those firms.6
• China’s finance ministry separately barred Chinese buyers from procuring products made by 46 U.S. companies, while allowing U.S.-funded enterprises operating in China to keep buying them.6

4. Ukraine pressure on Russian energy logistics reaches deeper into Siberia

• Russian air strikes wounded six people in Ukraine overnight Tuesday, according to local authorities cited by Reuters; the reported injuries were in Zaporizhzhia, Sumy and Kharkiv.8
• The strikes followed a Ukrainian attack on a Voronezh missile-electronics plant that the local governor said killed five people and injured dozens; Reuters said it could not independently verify details of the latest strikes.8
• Fuel restrictions have spread from Russian-occupied Crimea to Omsk and Novosibirsk in Siberia, with Omsk limiting gasoline to 40 litres per car and diesel to 80-200 litres depending on location.8

5. Taiwan starts a readiness drill as PLA aircraft activity continues

• Taiwan’s defense ministry said the Immediate Combat Readiness Exercise would run from Monday to Friday, moving training away from set-piece events toward more realistic war-simulation drills.9
• The ministry said the exercise would use actual troops, actual terrain, real-time execution and actual equipment, with emphasis on rapid peacetime-to-wartime transition and joint command, logistics and battlefield preparation.9
• On the same day, Taiwan said China sent 21 aircraft near the island, including J-16 fighters, KJ-500 airborne early-warning aircraft and Y-20 refuelling aircraft; 19 entered airspace southwest of Taiwan and continued into the Western Pacific.9
