Fed's Barr in Detroit: AI could push the neutral rate up, and more hikes are likely with prime at 7%

Federal Reserve Governor Michael Barr repeated on Tuesday that he expects the Fed to raise rates again, telling the Detroit Economic Club that "further policy adjustments are likely to be needed" in his base case, according to his prepared remarks. Bloomberg led with that line. It is the same sentence he used six days ago in a housing speech we covered here. What changed is the reasoning around it.

What is new in today's speech

• The inflation count. Barr said he finds only two months of data consistent with 2% core PCE inflation over the past 20 months, and that inflation has now been above the 2% target for five and a half years.
• Growth is speeding up, not slowing. Real GDP grew at roughly a 2% rate in the first half, and he expects a bit faster in the second.
• Jobs are not the constraint. Payroll growth has averaged about 80,000 a month this year, which he called close to breakeven given lower immigration, with unemployment at 4.1%.
• AI is feeding prices now. He said chip prices are surging, that the increases are spreading into other products, and that tech-driven stock gains are likely supporting spending by wealthier households.

The part the headline misses

The common read is that an AI productivity boom is good news for rates, because faster output growth eases inflation. Barr accepted the first half and rejected the conclusion. A lasting productivity gain, he argued, raises the return on investment and pulls down household saving, which lifts the equilibrium rate, or r*, and "implies a higher setting for the policy rate." He said it is too early to know whether that is happening, but it points toward higher rates, not lower ones.

The committee's own numbers already lean that way. In the September projections, the median longer-run funds rate rose to 3.2% from 3.1% in June, and the median for the end of 2026 is 4.1%, above the 3.75%-4% range the Fed set in its Sept. 16 statement. That median already implies one more quarter-point move this year. The 2027 median is also 4.1%, so the projections show no cuts next year either.

What markets are pricing

Treasury's daily yield curve put the 2-year note at 4.92% at Monday's close, up from 4.67% on Sept. 15, the day before the hike, and 92 basis points above the top of the funds range. The 1-year bill was 4.59%, against an effective funds rate of 3.88% on the Fed's H.15 release. A 1-year yield that far above the overnight rate is the market expecting policy to be higher a year out. The 10-year was 5.24% and the 30-year 5.56%.

What a quarter point does to a prime-based line

The bank prime rate, which most business lines of credit float on, stood at 7.00% through Sept. 25 on the H.15. Prime moves with the funds rate, so a quarter-point hike would take it to 7.25%. On a $250,000 line fully drawn at prime plus 2%, interest-only:

• At 9.00%: $22,500 a year, or $1,875 a month.
• At 9.25%: $23,125 a year, or about $1,927 a month.
• Each 25 basis points: $625 a year, about $52 a month. Two more hikes would add $1,250 a year.

The bigger issue is duration: the Fed median shows no relief in 2027, and a governor is arguing the floor may be rising. Our earlier walkthrough of the September hike for a contractor's line covers amortizing loans.

Why Detroit

Barr put Detroit-area unemployment near 11%, against 5% for Michigan and 4.1% nationally, and said 12% of U.S. auto assembly and parts jobs are in the metro. We count 11,289 independent businesses in Detroit on our Detroit page, and auto repair is the second-largest category, with 273 shops. Those shops carry parts inventory on revolving credit, which is where the next quarter point lands first. Our auto repair playbook covers the operating side.
