In a move reflecting escalating geopolitical risks, Iran has once again announced the closure of the Strait of Hormuz, leading to an immediate slowdown in global maritime shipping traffic. This strategic decision disrupts the recent recovery in the waterway, which serves as a critical artery for approximately 20% of global oil and liquefied natural gas supplies. According to analyst reports, this closure places significant pressure on energy supply chains at a sensitive moment for international diplomatic efforts.
Oil prices experienced sharp volatility in response to these developments; Brent crude spiked to $82.30 per barrel at the start of trading on June 22, 2026, before retreating toward $79 levels following news of progress in technical talks in Switzerland, per market data. Similarly, U.S. West Texas Intermediate (WTI) rose 2.64% to $78.62 per barrel (close June 22, 2026) ahead of the July contract expiry. Traders are now monitoring the sustainability of a maritime security mechanism discussed in Switzerland to ensure safe passage and mitigate the risk of sea mines, which experts estimate at roughly 80 in the main shipping channel.
