From April 2023 to April 2025, there has been an inverse relationship between the U.S. Dollar Index (DXY) and 10-year Treasury yields. When Treasury yields rise, the DXY tends to decline, and conversely, when yields fall, the dollar index tends to increase. This trend reflects the dynamics of capital flows and interest rate movements affecting the dollar's strength. Despite fluctuations, May 2025 has been the best month for the U.S. dollar within this period, although it experienced declines in four of the previous five months.
