Group 1 - The recent rise in gold prices is attributed to renewed risk aversion driven by geopolitical tensions and concerns over U.S. fiscal health, with gold surpassing $3,300 per ounce [1][2] - The U.S. government's trade policies, particularly the proposed tariffs on the EU, have negatively impacted U.S. stock indices, leading to a decline in major tech stocks [2] - Moody's downgraded the U.S. sovereign credit rating from Aaa to Aa1, reflecting growing concerns over U.S. fiscal stability, which has increased demand for gold as a safe-haven asset [2][4] Group 2 - Copper and oil prices have also risen significantly due to geopolitical risks and a weakening dollar, with WTI crude oil settling at $61.53 per barrel and Brent crude at $64.78 per barrel [3] - OPEC+ is expected to announce an increase in production, which may influence oil prices further, while the copper market has seen a price increase of over 5% in May [3] - The short-term impact of U.S. tariffs on metal exports is becoming evident, but low inventory levels are providing some support for metal prices [4]
