BLS Shake-Up Casts Doubt on CPI, Puts $2.1 Trillion TIPS Market at Risk

Wall Street is questioning the integrity of U.S. inflation statistics after President Donald Trump fired Bureau of Labor Statistics Commissioner Erika McEntarfer on 1 August, alleging manipulation of jobs data. The dismissal comes just one day before the BLS is scheduled to publish its monthly Consumer Price Index, heightening scrutiny of a data series that guides Federal Reserve policy and underpins markets from Treasury securities to consumer contracts. Analysts warn that any hint of political interference could erode confidence in the $2.1 trillion Treasury Inflation-Protected Securities market, whose payouts are linked directly to the CPI. "There’s real money on the line here," said Michael Feroli, chief U.S. economist at JPMorgan Chase. Ten-year TIPS yields have edged up to 1.864% since the firing, but strategists at TD Securities caution the market could "get nervous" if the next BLS chief is perceived as biased. Banks including Morgan Stanley say investors may demand higher compensation to hold TIPS or turn to private data sources if they doubt official figures, potentially widening term premiums across the Treasury curve. Portfolio managers at Natixis add that a wider margin of error around headline indicators may force markets to discount single-month prints and wait for longer trends before reassessing inflation expectations and the outlook for Fed rate cuts.
