What’s Happening

Odds that the Fed's upper bound reach 4.75% or higher before 2027 firmed sharply in early June after Kalshi contracts on a 2026 Federal Reserve rate hike jumped from 25.3% to 52% in a single week, while a separate contract on a hike before July 2027 climbed from 54% to 65%. The repricing followed a hotter-than-expected April jobs report and confirmation that the annual core PCE-adjacent CPI print hit 3.3% in April, well above the Federal Open Market Committee's 2% target. The current federal funds upper bound sits at 4.50%, meaning a single 25 basis-point hike would satisfy the threshold. [CNBC, Jun 5]

Cleveland Fed President Beth Hammack reinforced the hawkish turn on June 2, telling an audience the central bank may need to act "soon" against inflation pressures she described as "already too high and on a worrisome trend." Hammack said she is "more concerned about the growing risks of persistently elevated inflation than the risks to full employment," signaling that current policy may not be "sufficiently restrictive." Treasury markets corroborated the shift: 30-year yields touched 5.2% ahead of Memorial Day, the highest in 19 years, while the benchmark 10-year reached 4.7%, a level last seen in mid-2007. The CBO's February "Budget and Economic Outlook: 2026 to 2036" baseline assumes materially lower yields against $39 trillion in federal debt. [Yahoo Finance, May 30]

Counterweighting the hawkish data, Fed Chair Kevin Warsh holds only one FOMC vote and faces a committee that has remained cautious on aggressive moves in either direction, despite White House pressure for lower rates. The Q3 2026 CPI-W reading will set the Social Security 2027 COLA, giving the committee a politically sensitive inflation window through September. For the Fed's upper bound to reach 4.75% or higher before year-end, the FOMC would need to break from its current pause at one of the remaining 2026 meetings — a path consistent with Hammack's framing but not yet endorsed by the broader committee.
