The 10-year Treasury yield jumped to 8.07% on April 13, 1987, representing a 4.3 standard deviation move above its 60-day average of 7.28%. This extreme deviation signals a major shift in bond market sentiment. The spike occurred amid record-low unemployment (4.30%) and rising inflation (CPI up 1.8% over 3 months), suggesting investors were pricing in significant inflationary pressure. GDP growth of 1.4% over the quarter indicates a robust economy potentially overheating. This rare statistical event in Treasury markets often precedes major economic turning points or policy shifts.
