Article content CHICAGO — The $22 trillion market for U.S. Treasury securities may get a reality check from the Federal Reserve this week following a plunge in interest rates that bucked expectations of higher yields this year as the economy rebounds from the COVID-19 pandemic. Yields, which move inversely to prices, have been in a downward trend since the last Federal Open Market Committee meeting in June. The market initially perceived the Fed as being a bit hawkish as policymakers last month projected an accelerated timetable for rate hikes and opened discussions on ending crisis-era bond purchases amid a backdrop of rising inflation.
