Jon Faust, a researcher at the Center for Financial Economics at Johns Hopkins University who served as a senior adviser to Federal Reserve Chairman Powell, said that the Iranian conflict "may cause oil prices to soar, market confidence to collapse, and even become the fuse of economic recession", but its ultimate impact is still difficult to predict. In an interview, he pointed out: "Economic recessions often begin with some kind of shock - now such a crisis may be brewing in the Middle East, and the probability is slightly higher than before." The Federal Reserve will hold an interest rate meeting from Tuesday to Wednesday this week, and the market generally expects that the benchmark interest rate will be maintained in the range of 4.25%-4.5% for the fourth consecutive time. Foster believes that the core suspense of this week's meeting is whether Powell will send a clearer signal: Is the risk of inflation rebound greater, or is the weak job market more worrying? "This will reveal the Fed's policy orientation in the second half of the year." He added that the Fed has not yet clearly leaned towards either side.
