美国袭击委内瑞拉：发生了什么？有何影响？

Group 1: Venezuela's Oil Market Impact - Venezuela has the largest proven oil reserves globally, approximately 300 billion barrels, accounting for 17% of the world's total, but its current oil production is only about 1 million barrels per day, representing roughly 1% of international supply [2] - The recent U.S. military action against President Maduro may cause short-term volatility in oil prices, but the long-term impact on the global oil market is expected to be negligible due to Venezuela's limited market share and the nature of its heavy sour crude oil, which requires extensive processing [2][3] - The core factors influencing international oil prices remain supply and demand dynamics, with a persistent oversupply expected to continue into 2026, driven by geopolitical challenges among oil-producing countries and a decline in global oil demand due to economic downturns and the rise of renewable energy sources [3] Group 2: Gold Market Dynamics - The recent geopolitical tensions have led to increased investor interest in safe-haven assets, pushing gold prices to new highs, with forecasts indicating that central banks' net purchases of gold will reach 950 tons in 2026, up from a previous estimate of 900 tons [4] - The ongoing uncertainty in the global economy and political landscape, including factors like U.S. midterm elections, is likely to sustain demand for gold, providing solid support for its price in the long term [4]
