Goldman Sachs warns that due to Trump's global trade war and a weakening US dollar, the US core inflation rate is expected to reach 3.8% in December this year, significantly higher than the Federal Reserve's March forecast of 2.8%. Goldman Sachs anticipates the core goods inflation rate to surge from 0.4% in March to 6.3% in December. The main price increases are in used cars, household appliances, audiovisual equipment, jewelry and watches, and pharmaceutical products. This upward inflation trend may offset the anti-inflation progress made previously.
