According to The Kobeissi Letter, the US government's deficit to GDP ratio was significantly impacted by interest payments last year. The primary deficit was 3.3%, but interest payments added 3.1 percentage points, bringing the total deficit to 6.4%. This situation highlights the government's need for lower interest rates, which could affect trading strategies involving US debt securities and the USD. Investors should monitor interest rate policies closely, as they can influence bond yields and currency valuations.
