There is a number that explains most of what has happened in markets over the last few years, and it is not the level of the stock market. It is this: inflation in the United States has now been above the Federal Reserve's 2% target for more than five straight years.
Five years is a very long time in central banking. It is long enough that a whole generation of new workers has never known stable prices. It is long enough to change how people behave. And it is the reason the Fed is still talking about raising rates in late 2026 rather than cutting them.
Where inflation actually is
The most recent full reading, published in mid-August 2026, covered the twelve months to July. It showed:
- Headline inflation of 3.4%, down a touch from 3.5% the month before.
- Core inflation of 2.5%, which strips out food and energy.
Those two numbers tell slightly different stories, and the gap between them is the whole argument.
Core at 2.5% is not far off target. If that were the only number that existed, the Fed would probably be relaxed. Headline at 3.4% is a different matter, and the difference is largely energy, which we will come back to.
Why "just get it back to 2%" is harder than it sounds
People often assume bringing inflation down is a single action, like turning off a tap. It is not. Inflation comes from several places at once, and they respond to interest rates at very different speeds.
Goods versus services
Prices of physical things - cars, furniture, appliances - respond fairly quickly to higher borrowing costs, because most people buy them on credit. Make credit dearer and demand cools.
Services are stickier. The cost of a haircut, a dentist appointment, insurance or a restaurant meal is mostly the cost of people's time. Wages do not fall easily. Once pay has risen, it stays risen, and businesses pass that through in prices. This is why the last stretch of an inflation fight is always the slowest.
Housing lags everything
Shelter is one of the biggest single components in the inflation basket, and it is measured in a way that trails reality by a long way. Rents agreed today take many months to show up fully in the official figures. That means the inflation number you read is partly describing the housing market of a year ago.
Energy keeps interrupting
This is the big one in 2026. Just as inflation looked to be settling, oil pushed sharply higher on Middle East supply worries, trading around $91 a barrel in early September after a near 9% weekly gain. Energy feeds into everything: transport, manufacturing, food distribution, plastics, heating.
A central bank is technically supposed to look through a one-off energy spike. The trouble is that after five years of above-target inflation, nobody is confident it stays a one-off. That is exactly the problem.
The credibility problem
Here is the thing that keeps central bankers awake. Inflation is partly psychological.
If everyone believes prices will rise 2% a year, workers ask for roughly 2% pay rises and businesses plan roughly 2% price increases, and the belief becomes self-fulfilling in a manageable way.
If people stop believing it - if five years of overshoot teaches them that 3% or 4% is the new normal - then pay demands and pricing decisions get built around that higher number, and inflation becomes much harder to shift. Economists call these inflation expectations, and protecting them is the real reason a central bank will accept a slower economy rather than tolerate another year of overshoot.
This is the backdrop to Fed chair Kevin Warsh's firm message at Jackson Hole in August 2026. It is less about the exact level of inflation today and more about making sure people still believe the target means something.
What it feels like for households
Inflation at 3.4% does not sound dramatic. Compounded over years, it is.
Something that cost $100 five years ago, rising at an average of just over 3% a year, costs roughly $117 today. Wages for many people have not kept pace across that whole stretch, which is why the official statistics can improve while people insist things still feel expensive. Both can be true. The rate of increase has slowed; the accumulated increase has not been undone.
Prices very rarely fall back. Falling prices across the board, called deflation, sounds appealing but is usually a symptom of something badly wrong with the economy. What normally happens instead is that prices stop rising quickly and wages gradually catch up.
What it means for markets
Persistent inflation reshapes almost every market relationship.
Bonds suffer. A fixed interest payment is worth less when prices are rising, so investors demand a higher yield to compensate. This is a large part of why the ten-year Treasury yield has been near multi-year highs, sitting around 4.78% in early September.
Cash stops being punished. When rates are near zero, holding cash costs you. With policy at 3.50% to 3.75%, cash pays a real return if inflation keeps easing.
Shares get pickier. Companies that can raise their prices without losing customers do well. Companies that cannot get squeezed from both ends by rising costs and flat revenue.
Hard assets get attention. Gold and, increasingly, bitcoin attract money from people worried about the purchasing power of currency. That is part of the reason crypto rallied in early September even as rate-hike fears rumbled on.
What to watch next
The August inflation report lands on 11 September 2026, and it arrives before the Fed's next decision. Watch three things:
- The core number. It matters more than the headline for policy, because it filters out the oil noise.
- Services excluding housing. This is the wage-driven part, and it is the piece the Fed watches most closely.
- The monthly rate, not just the annual one. The annual figure is heavily influenced by what happened a year ago. The month-on-month change tells you what is happening now.

The honest summary
Inflation is not out of control, and it is not solved. It has spent five years grinding slowly toward a target it has never quite reached, interrupted every time it gets close by something new - and this year that something is oil.
For your money, the practical implications have not changed much: clear expensive debt while rates are high, make sure your cash is actually earning something, and do not assume the cost of living quietly reverses. For your trading, expect inflation releases to keep being the biggest scheduled movers on the calendar for a while yet.
How inflation is actually measured
It helps to know where the number comes from, because it explains several things that otherwise look strange.
Statisticians build a notional shopping basket meant to represent what a typical household buys. It contains hundreds of items, each given a weight according to how much of the average budget it consumes. Housing takes a very large share. Food and transport take substantial shares. Individual items like cinema tickets take tiny ones.
Every month, prices are collected for those items and the basket's total cost is compared with a year earlier. The percentage change is the inflation rate.
Two consequences follow from this design.
First, your personal inflation rate is almost certainly different from the published one. If you rent in an expensive city and drive a lot, you are far more exposed to housing and fuel than the average basket implies. If you own your home outright and work from home, considerably less. Neither of you is wrong to feel the official number does not describe your life.
Second, the basket gets adjusted over time as spending habits change, and adjustments to quality are made too. If a product improves substantially while its price stays the same, statisticians may record that as an effective price fall. This is defensible in principle and controversial in practice, and it is one reason some people distrust the figures.
What matters more: the monthly or the annual figure?
Most headlines quote the annual rate - prices compared with twelve months ago. It is the more stable measure, but it has a significant flaw for anyone trying to understand what is happening right now.
The annual figure includes eleven months of old news. If prices jumped sharply last autumn and have been flat since, the annual rate will stay elevated for months purely because of that old jump, long after the pressure has ended. When that month eventually drops out of the calculation, the annual rate falls sharply without anything actually changing in the present.
Professionals therefore watch the month-on-month change, and often the three-month annualised rate, which takes recent months and projects them forward. These are noisier but far more current.
When you see commentary about inflation "momentum" or the "run rate", this is what is being discussed. It is entirely possible for the annual rate to be falling while the monthly momentum is rising, which is one of the more dangerous situations for a central bank and one of the easiest to miss if you only read headlines.
Three things that would genuinely change the picture
- Wage growth falling clearly. Services inflation is mostly wages. If pay growth cools toward levels consistent with 2% inflation, the last mile becomes achievable rather than aspirational.
- Energy stabilising. With crude around $91 after a sharp weekly rise, energy is currently pushing the wrong way. A sustained retreat would take real pressure off headline inflation within a couple of months.
- Housing costs catching down. Because shelter is measured with a long lag, cooling in the actual rental market takes many months to appear. If current market rents are softer than the official data reflects, there is disinflation already in the pipeline that has simply not shown up yet.
That last point is the strongest argument the doves on the Fed have. It is also unprovable in real time, which is precisely why the committee is split.
