Under heavy political pressure, Powell is about to make a speech. U.S. debt ends four consecutive increases.

Finance and Economics APP understands that as investors are eagerly awaiting for Federal Reserve Chairman Powell to give a speech on Tuesday evening, the U.S. treasuries may end their four-day consecutive rally. As of the time of writing, the yield on the 10-year U.S. treasury rose nearly 1 basis point to 4.39%, partially reversing the 10 basis points decline since the weak U.S. June PPI data was released last week. The yields on the 20-year and 30-year U.S. treasuries also increased by about 2 basis points, respectively at 4.95% and 4.96%.
