Over weekend: Iran rejected talks, dollar up, gold down.

Last Friday, optimism surged in the market as the Iranian Foreign Minister announced that merchant ships could pass through the Strait of Hormuz. The US dollar index once hit a new low since February, but later regained all losses of the day and returned to above 98, ultimately closing up 0.01% at 98.22; On Monday, as Trump's optimistic messages were refuted one by one by Iran over the weekend, the US Composite Index jumped high. The benchmark 10-year Treasury yield closed at 4.251%, while the 2-year Treasury yield sensitive to the Federal Reserve policy rate closed at 3.712%. On Monday morning (Beijing time, April 20th), spot gold opened lower in the Asian market, trading near $4776 per ounce, and may test the $4750 per ounce mark during the day. The situation between the United States and Iran escalated again over the weekend, with the United States and Iran accusing each other of violating the ceasefire agreement by attacking ships, and the Strait of Hormuz closed again. Iran warns that war may restart at any time, and the armed forces remain fully prepared. Affected by the opening of the Strait of Hormuz, international oil prices plummeted sharply last Friday. WTI crude oil fell more than 10% at one point during the day, but regained some lost ground in the late trading, ultimately closing down 6.3% at $86.89 per barrel; Brent crude oil ultimately closed down 6.49% at $88.17 per barrel. On Monday, WTI crude oil opened significantly higher and returned above $90.
