Fed Hammack says rate hikes possible if inflation persists

May producer‑price inflation jumped 6.5% year‑over‑year, topping the 6.4% consensus and marking the highest reading since November 2022, while core PPI held at 4.9%—below the 5.4% forecast [1].

Inflation data and Fed dissent

The headline PPI reading signals strong upstream price pressure, but the unchanged core PPI suggests the surge is driven mainly by volatile energy and commodity costs rather than a broad‑based acceleration. The same pattern appeared in the latest CPI report, where headline inflation rose to 4.2% while core CPI stayed at 2.9% [1].

Cleveland Fed President Beth Hammack, who voted to hold rates but dissented on the statement’s bias toward future cuts, said the “easing bias” is no longer appropriate given the outlook. She highlighted that inflation pressures remain broad‑based and that oil at $122 a barrel is adding further upside risk [2]. Hammack also noted the economy’s resilience—unemployment steady at 4.3%—but warned of upside risks to inflation and downside risks to growth.

Market reaction and policy outlook

Bond yields rose modestly as investors priced in the possibility of a future hike, while the dollar edged higher against a basket of peers. The mixed inflation picture left rate‑sensitive equities muted, but commodities and energy stocks found support from the elevated producer‑price and oil numbers [1].

Bank of America analysts, reacting to the same data, now project three Fed hikes in 2026, citing “unambiguously worse” inflation and a loss of patience for supply‑shock‑driven price spikes [3]. Their forecast of up to 75 basis points of rate increases reflects a shift from earlier expectations of a hold‑through year.

What to watch

• June 28 Fed meeting – decision on whether to maintain the pause or begin tightening.
• Core PCE inflation – the Fed’s preferred gauge, due later this week; a reading above 3% could tip the balance toward hikes.
• Oil price movements – sustained levels above $120 a barrel would reinforce Hammack’s inflation concerns.

The divergence between headline and core inflation underscores the Fed’s dilemma: a hot upstream price environment that could eventually filter through to consumer prices, versus a core backdrop that still offers room for patience. How the June meeting resolves this tension will shape the trajectory of rates for the rest of the year.
