The United States has commenced new military operations against Iran following the collapse of a temporary ceasefire, leading to increased instability in the Strait of Hormuz and fluctuations in global energy prices.

由於臨時停火協議失效，美國已對伊朗展開新軍事行動，導致霍爾木茲海峽不穩定程度增加，並引發全球能源價格波動。

The current geopolitical friction originated from a conflict initiated on February 28, which was temporarily mitigated by a Memorandum of Understanding signed in mid-June. However, the cessation of hostilities terminated after Iran targeted three commercial vessels in the Strait of Hormuz and conducted strikes against US military installations in Bahrain and Kuwait. In response, the US administration revoked Iranian oil sanctions waivers and executed strikes against approximately 90 military targets, including coastal surveillance and logistics infrastructure, to ensure the continued viability of the Strait of Hormuz as a transit route.

目前的地緣政治摩擦源於 2 月 28 日爆發的衝突，雖於 6 月中旬簽署諒解備忘錄暫時緩解，但伊朗隨後在霍爾木茲海峽攻擊三艘商船，並襲擊美國在巴林與科威特的軍事設施，導致停火協議終止。作為回應，美國政府撤銷了伊朗的石油制裁豁免，並對約 90 個軍事目標（包括海岸監測與物流基礎設施）執行打擊，以確保霍爾木茲海峽作為運輸航道的持續可行性。

From an economic perspective, the International Monetary Fund has identified this conflict as the primary risk to global growth, which is projected to decline to 3 percent this year. The potential closure of the Strait of Hormuz—a conduit for 20 percent of global oil and LNG supplies—has induced volatility in crude benchmarks; Brent crude surged toward $80 per barrel following the US declaration that the ceasefire had concluded. Furthermore, QatarEnergy has suspended production increases at the Ras Laffan complex due to safety concerns following an attack on the Al Rekayyat LNG tanker, potentially exacerbating supply shortages in European and Asian markets.

從經濟角度來看，國際貨幣基金組織將此衝突視為全球成長的主要風險，預計今年成長率將下降至 3%。霍爾木茲海峽作為全球 20% 石油與液化天然氣 (LNG) 供應的通道，其潛在的封鎖風險已導致原油基準價格波動；在美國宣布停火結束後，布倫特原油價格飆升至每桶近 80 美元。此外，由於 Al Rekayyat 液化天然氣油輪遭襲擊，QatarEnergy 出於安全考量，暫停了 Ras Laffan 綜合設施的增產計劃，可能加劇歐洲與亞洲市場的供應短缺。

Institutional responses vary by stakeholder. The Australian Treasury, represented by Jim Chalmers, has noted that prolonged instability poses significant inflationary risks and threatens domestic economic growth. Conversely, some analysts suggest that both the US and Iranian administrations possess financial incentives to achieve a rapid rapprochement to avoid further economic degradation, particularly given the proximity of US midterm elections and Iran's own fiscal constraints.

各利益相關者的體制反應不一。澳洲財政部代表 Jim Chalmers 指出，長期的不穩定將帶來顯著的通貨膨脹風險，並威脅國內經濟成長。相反地，部分分析師認為，鑑於美國中期選舉在即以及伊朗自身的財政限制，美伊兩國政府均有經濟誘因促成快速和解，以避免經濟進一步衰退。

Global markets remain vigilant as the US and Iran oscillate between military escalation and the possibility of renewed diplomatic negotiations.

由於美國與伊朗在軍事升級與恢復外交談判的可能性之間搖擺，全球市場仍保持警戒。
