Here’s What’s Happened

• The Federal Reserve raised the target range for the federal funds rate by 25 basis points to 3.75%–4.00% on September 16, 2026, its first rate increase since 2023. The Federal Open Market Committee approved the move by a unanimous 12–0 vote.
• Federal Reserve Chairman Kevin Warsh characterized the US economy as expanding at a solid pace, with the unemployment rate “little changed” and productivity growth strong. He described inflation as “too high and has been for too long.”
• The Fed’s updated Summary of Economic Projections shows the median federal funds rate projection revised upward across every year through 2029 relative to its June projections: to 4.1% from 3.8% for the end of 2026, and to 3.9% from 3.4% for 2028. The Fed’s inflation and growth projections moved only modestly by comparison: the Fed now projects Personal Consumption Expenditures (PCE) inflation at 3.7% for 2026, versus 3.6% in June, and real GDP growth at 2.3%, versus 2.2%. Its unemployment rate projection for 2026 fell to 4.1%, from 4.3% in June.
• Separately, the Mortgage Bankers Association reported that the average 30-year fixed mortgage rate rose to 6.97% in the week to September 16, 2026, from 6.85% the prior week. These rates track the 10-year Treasury yield rather than the federal funds rate directly.
• The US Energy Information Administration’s weekly data show gasoline prices reaching $4.17 per gallon in the week of September 14, 2026, up 37.3% year over year.
• The New York Fed’s Consumer Credit Panel shows credit card balances rising 4.5% year over year (up $54 billion) to $1.263 trillion in the second quarter of 2026, from $1.209 trillion a year earlier.

Fed Rate Rise: Coresight Research Analysis

1. Higher Revolving-Credit Costs Are the Point, and Consumers Are Already Carrying More of Them

Raising the cost of revolving credit is the effect that a rate increase is designed to have on consumer borrowing and spending.

Consumers are entering this cycle already carrying more of that debt:

• The New York Fed’s Consumer Credit Panel shows credit card balances rising 4.5% year over year (up $54 billion) to $1.263 trillion in the second quarter of 2026, from $1.209 trillion a year earlier.
• Per NY Fed data, credit card debt, and total consumer debt, rose most sharply among older age groups (year over year) in the second quarter of 2026. Credit card balances were up 7.8% among consumers aged 70+ versus up 1.0% among those aged 18–29.
• The Federal Reserve’s data show revolving credit, in total, up 4.9% year over year in the second quarter, versus up 4.2% in the first quarter.
• New York Fed analysis found that the share of credit card balances 90+ days delinquent climbed from 7.6% in the third quarter of 2022 to 12.8% in the first quarter of 2026. This is due mostly to older, charged-off debt remaining on lenders’ books for longer rather than a fresh wave of missed payments; the rate of new delinquencies has stayed broadly stable since 2024.

A further 25-basis-point increase in the cost of carrying that debt lands on a base that was already expanding.

2. Mortgage-Linked Retail Faces a Separate, Treasury-Driven Squeeze

The rate increase does not flow through to mortgage-linked retail categories in the same direct way.

The Mortgage Bankers Association reported that the average 30-year fixed mortgage rate rose to 6.97% in the week to September 16, 2026, from 6.85% the prior week. These rates track the 10-year Treasury yield rather than the federal funds rate.

The 10-year Treasury yield this week climbed above 5%, a rate not seen since mid-2007, as bond yields have risen worldwide.

Home and home-improvement retail, including Home Depot, Lowe’s and Wayfair, remain constrained by that separate, already-elevated cost of financing rather than by the Fed’s decision itself.

3. The Timing Compounds an Already Fading Consumer Tailwind

The rate increase adds to, rather than introduces, a set of pressures already building on the consumer:

• The US Energy Information Administration’s weekly data show gasoline prices again exceeding $4 per gallon (at $4.17) in the week of September 14, 2026, up 37.3% year over year (versus up 30.2% in the prior week).
• Total headline inflation is on course for a sixth consecutive year above the Fed’s 2% target, a risk that we have flagged since the start of the year.
• Coresight Research estimates that more than 30% of this year’s approximately $50 billion increase in tax refunds was redirected to retail spending, a benefit that is fading from household budgets heading toward the holiday season.

Lower-income households face a larger compounding effect from higher borrowing costs, elevated gasoline prices and persistent inflation together. Higher-income households are generally better placed to keep driving spending growth. This is consistent with the “K-shaped” pattern in the consumer economy that Coresight Research has previously identified, whereby more affluent consumers drive spending growth while lower-income consumers contract areas of their spending.

How We Got Here

Why Inflation Reaccelerated in 2026

• Inflation has run above the Fed’s 2% target for more than five years, a stretch comparable to 2003–2008.
• Headline inflation had been moderating through 2024 and into 2025.
• Two factors reversed that trend in early 2026: tariffs announced in 2025 began flowing through retail supply chains with a multimonth lag, and the closure of the Strait of Hormuz following the outbreak of conflict involving Iran in late February 2026 triggered a sharp rise in energy prices.
• Total CPI rose from 2.4% in February to 4.2% in May, before easing to 3.4% by August 2026. Coresight Research’s retail-specific inflation estimate rose more modestly, running between 2.2% and 2.6% through May before easing to 1.8% by August, with the sharpest pressure in categories such as apparel (4.8% in May) and sports equipment (4.2% in May).

Why the Fed Held, Then Acted

The Fed left its policy rate unchanged at 3.50%–3.75% for most of 2026, even as its own signals turned more hawkish:

• At its June meeting, the Committee held rates steady but raised its median year-end projection to 3.8%, up from 3.4% in March, and removed language pointing to further rate cuts.
• At its July meeting, the Committee held again; Warsh said a majority of the Committee judged it wiser to await further data before acting.
• At the Jackson Hole policy symposium in August, Warsh said financial conditions could not be described as restrictive and pointed to rising commodity prices, hardening market expectations of a September increase.
• By September 16, the Committee judged that its standard for holding rates—clear, sufficiently fast progress toward the inflation objective—had not been met, and it raised the target range by 25 basis points.

What We Think

The near-term effect of the rate increase is to raise the cost of consumer borrowing slightly, adding modestly to the retail-spending pressures discussed above and representing another headwind for holiday-season demand. Per our new holiday consumer survey, 41% of shoppers expect credit cards to be among their most-used payment methods for holiday 2026 (a close second to debit cards at 47%), and 26% expect to put a greater share of purchases on credit this year than last year (versus 14% for less); and that 26% skews toward consumers with an income of $100,000+).

Its intended effect, though, is to bring inflation back toward the Fed’s 2% target over time, as the Fed’s own policy statement sets out. If that succeeds, slower price growth would itself benefit consumers, including the higher-income households currently driving spending growth.

The rate rise may accelerate a divergence between financially resilient and financially constrained consumers during holiday shopping. Higher-income households are not insulated from the cost of revolving or short-term credit, although they are generally better placed to absorb or avoid it. Our existing “K-shaped” view of the consumer economy—in which higher-income households continue to drive retail spending growth while lower-income households absorb a disproportionate share of pressure from higher costs—is reinforced by the rate rise.

Retailers with a lower-income skew include Dollar General, Dollar Tree, Family Dollar and Walmart. Those with a higher-income skew include Costco, Macy’s, Sam’s Club, Target and Trader Joe’s. See our Who Shops Where? report for major US retailers’ proprietary shopper profiles, including by income group.

• We will shortly be publishing our US Holiday Survey and Outlook, with a detailed look at consumers’ expected responses to inflation during the holiday season.
• We will also shortly publish our analysis of last-mile retailing in the holiday season, which will look at the issue of rising shipping costs in US retail.

Longer-Term Structural Forces Behind Persistent Inflation

We point to demographic shifts as a source of inflationary pressure over the near to long term, and separate from the tariff- and energy-driven causes discussed above:

• Net immigration into the US declined from 2.7 million in 2024 to 1.3 million in 2025; the US Census Bureau estimates it will total just 321,000 in 2026, reducing labor-supply growth.
• Almost one in five Americans is now aged 65 or older, per the US Census Bureau. A reduced working-age population must increasingly support a larger retired cohort’s demand without a matching increase in labor supply.
• Retirees tend to spend rather than save. Economists Charles Goodhart and Manoj Pradhan have argued, in “The Great Demographic Reversal,” that a shrinking pool of savers can put upward pressure on interest rates because there is less capital available to lend.
• The US general fertility rate fell to 53.1 births per 1,000 women aged 15–44 in 2025, the lowest on record according to the Centers for Disease Control and Prevention, pointing to further labor-force constraints roughly two decades from now.

Coresight Research expects these structural upward pressures on costs and prices to sustain the case for automation and AI-driven productivity tools over the medium to long term.

Implications for Brands/Retailers

Brands or Retailers Poised to Gain Advantage

• Retailers and brands with a higher-income-skewing customer base are better placed to sustain spending growth through the holiday season, although these consumers are not fully insulated from higher borrowing costs.
• Discretionary categories that benefited from this year’s tax-refund flow, such as apparel, may see continued strength for as long as that spending persists, although the tailwind is fading.

Brands or Retailers That Risk Losing Advantage

• Retailers and brands with a lower-income-skewing customer base face a compounding effect from higher revolving-credit costs, elevated gasoline prices and persistent inflation together, given a higher debt-to-income burden at that end of the market.
• Retailers and brands that are more exposed to credit, such as electronics, furniture and other big-ticket home goods, are likely to be more vulnerable.
• Home Depot, Lowe’s, Wayfair and other home and home-improvement retailers remain constrained by mortgage rates that are already elevated, indirectly to interest rates, as bond yields remain high.
