US Treasury Adjusts Series I Bond Rates for May-October Cycle
The US Treasury announced a new Series I bond composite rate of 3.98% for the May-October period, down from the previous 3.11%. The rate comprises a 2.86% inflation-adjusted component and a 1.10% fixed rate—a decline from October’s 1.20% fixed benchmark. These bonds recalibrate semi-annually, blending variable and fixed rates to determine investor yields.
While the inflation-linked portion remains static for six months post-purchase, the fixed rate persists for the bond’s lifetime. The Treasury maintains opacity around its calculation methodology. This adjustment reflects broader macroeconomic shifts but carries no direct implications for cryptocurrency markets.
