The October CPI report came in hotter than Wall Street expected, with consumer prices rising 0.4% against expectations of 0.3%. Core inflation, excluding food and energy, increased 0.3% rather than the anticipated 0.2%. September had already produced a 0.6% increase in headline prices, and now October has added another increase on top of that. The financial press will point out that inflation slowed from the previous month. That is technically correct, but the underlying problem is that price pressures are continuing to spread through the economy while Washington remains convinced that adjusting interest rates will somehow resolve the consequences of its own policies.
The government cannot even provide the normal annual inflation comparison this month. The 2025 government shutdown prevented the Bureau of Labor Statistics from collecting the October data needed to calculate a reliable year-over-year figure. September’s annual CPI was 3.7%, but October must be judged primarily through the monthly figures and other available indicators. We have a Federal Reserve preparing to raise rates, a government running enormous deficits, and an economy absorbing the consequences of war, tariffs, and expensive energy. Yet the political establishment continues treating each monthly inflation report as though it were an isolated event.
Core inflation failed to moderate. Energy prices have been extremely volatile because of the war with Iran, and gasoline prices have recently retreated from their highs. If inflation were simply an oil problem, we should be seeing much clearer relief elsewhere. Instead, core prices increased at the same 0.3% monthly pace recorded in September. The costs of operating a business have already been affected by transportation, insurance, imported materials, and financing. Those expenses do not disappear the moment crude oil declines. Businesses must recover their costs, and those increases work their way through the economy over time.
Federal Reserve Governor Christopher Waller has now warned that a 50-basis-point rate increase should be considered in December if core inflation remains elevated. He also acknowledged that the enormous expansion of artificial intelligence infrastructure and higher energy prices may continue generating inflationary pressure. The Fed is confronting an economy in which demand for electricity, equipment, construction, and capital is being driven by enormous investment in data centers, while the war has raised the cost of transporting energy and goods. Raising interest rates cannot manufacture electricity, repair damaged oil infrastructure, or reopen a shipping route threatened by military conflict.
The war with Iran has exposed the limitations of monetary policy. Higher oil prices do not remain confined to gasoline stations. Diesel affects trucking, agriculture, construction, and distribution. Shipping insurance increases when tankers face military threats, and those costs eventually reach businesses and consumers. Waller cited reports that insurance and additional precautions surrounding oil shipments were adding between $20 and $30 per barrel to transportation costs. Even if oil retreats, companies have already paid those expenses. There is a considerable difference between a temporary decline in a commodity price and the reversal of costs that have become embedded throughout the economy.
Tariffs introduce another complication. Washington imposes duties on imported goods and then acts surprised when importers, manufacturers, and retailers face higher costs. Some businesses absorb part of those expenses through reduced profit margins, while others pass them along to customers. The extent varies by industry and competitive conditions, but tariffs are not a mechanism for reducing consumer prices. The Fed cannot offset every cost increase caused by trade policy without imposing additional pressure on borrowing and investment.
The greater contradiction is that Washington remains the largest structural borrower in the economy. The federal government continues issuing debt to finance expenditures that tax revenues cannot cover, including growing interest obligations. When the Fed raises interest rates to restrain private-sector demand, it also increases the cost of refinancing government debt over time. Treasury yields are determined in the bond market, where investors evaluate inflation, fiscal risk, liquidity, and the availability of capital. The Fed can influence short-term rates, but it cannot dictate what investors must accept to lend Washington money for ten or thirty years.
This creates a serious problem for the real estate market. Higher Treasury yields can push mortgage rates upward even when housing demand is weakening. Homeowners who refinanced during the pandemic are reluctant to surrender mortgages carrying exceptionally low rates, while prospective buyers face higher financing costs and home prices that remain far above their pre-pandemic levels. The result is a market where transactions can stagnate without producing the broad price declines buyers expect. A household that needs financing experiences a very different housing economy from someone purchasing with cash.
The labor market is another reason the Fed should be cautious about assuming it can fine-tune the economy. Waller described a labor market characterized by limited hiring and limited firing. Employers may be retaining existing workers while delaying new recruitment, particularly as businesses reassess costs and investment in artificial intelligence. Unemployment can remain relatively stable even while opportunities for people seeking new jobs deteriorate. Raising rates into that environment risks weakening business investment and employment without addressing the supply-side forces responsible for much of the inflation.
There is also a growing divergence between the financial markets and the domestic economy. Large technology companies are spending enormous sums constructing data centers and acquiring specialized equipment. That investment can support economic growth while placing additional demand on electricity, construction materials, and skilled labor. Meanwhile, smaller businesses face higher borrowing costs, and households continue struggling with the cost of necessities. GDP may expand, but that does not mean the benefits are being distributed evenly across the economy. Capital is concentrating in sectors capable of financing enormous projects while businesses dependent upon affordable credit face increasing pressure.
The October report reinforces the danger of treating inflation as something that can be managed through a single interest-rate decision. The Fed left its benchmark rate at 3.75% to 4.00% in October, and markets are now anticipating another increase in December. The question is whether higher rates will actually resolve the forces driving prices upward or simply add to the financial strain on borrowers. Inflation caused by excessive demand is one problem. Inflation aggravated by war, energy disruptions, tariffs, and government borrowing is another.
We have entered a period where the traditional assumptions behind monetary policy are being tested. The government borrows heavily, geopolitical conflict disrupts supply chains, and enormous capital expenditures place pressure on energy and industrial capacity. The Fed responds by adjusting the price of short-term money, but it has no authority over the political decisions creating these conditions. The bond market will ultimately determine how much confidence investors place in the government’s ability to finance its obligations.
