Wu Blockchain has learned, according to The Kobeissi Letter, that the U.S. Treasury has issued approximately $25.4 trillion in Treasury bills (T-Bills) over the past 12 months, bringing the total issuance to $36.6 trillion, with the proportion of short-term debt rising to 69.4%, close to a historical high. It is noted that the U.S. is rolling over long-term obligations with short-term debt maturing in "a few months," causing public debt interest to fluctuate almost in sync with the federal funds rate. If inflation rises again and the Federal Reserve is forced to raise rates again, interest costs will climb to unprecedented levels, and the U.S. debt crisis is intensifying.
