Why the Fed is still hiking: The inflation mechanics

A rate hike is not just a number changing on a board. It is a deliberate squeeze on liquidity that makes borrowing more expensive and saving slightly more rewarding, and right now the Federal Reserve is tightening that screw. After the committee voted on September 16 to lift the federal funds target range by 25 basis points to 3.75% to 4.00%, the central bank has signaled that this was the opening move, not the finale.

The core question on every investor's mind is simple. Why are rates going up when the stock market is wobbling and the Nasdaq just posted its longest losing streak since 2008? The answer lies in the disconnect between asset prices and the cost of goods. The Fed is looking at the Consumer Price Index, where September headline inflation hit 3.7% year over year. That is nearly double their 2% target, and for policymakers, that gap is a crisis of credibility that must be closed before growth concerns can take priority.

The Inflation Signal

Inflation is the primary driver here, and it is proving remarkably sticky. UBS, which recently revised its outlook to expect three total hikes, points to the fact that price pressure has failed to retreat convincingly toward the target. Even if headline numbers show a slight dip, core inflation remains elevated, keeping policymakers on a tightening path into early 2027.

The data from the Bureau of Labor Statistics is the benchmark that matters most. When the CPI was released on October 14, it rose 0.6% from the previous month, with core CPI up 0.3%. Gasoline prices accounted for more than half of the overall increase, but the underlying trend in services is what keeps the Fed's hawkish camp awake. As long as these readings resist the downward trajectory, the Fed will prioritize its inflation-fighting credibility over near-term growth risk.

Market Expectations vs. Reality

There is a fascinating tension between what the market prices in and what the Fed actually does. According to CME FedWatch Tool data, traders are currently pricing in an 83.9% chance that the central bank will keep interest rates unchanged at the October 27-28 meeting. This is a substantial shift from the 49% probability recorded just a month ago, suggesting that the market is betting on a pause.

However, this view is not universal. UBS stands as a firm outlier, arguing that the September hike was just the first of three steps. They expect two more quarter-point hikes, one in December 2026 and another in March 2027. This divergence highlights the uncertainty in the macro debate. While some watchers decline to signal near-term increases, the bank's rationale is that the current level of policy is not yet restrictive enough to bring inflation under control.

The Employment Factor

You cannot talk about the Fed without mentioning the labor market, and this is where the mechanics get complex. UBS argues that resilient labor market conditions are a key force keeping policymakers on a tightening path. If people are still employed and earning, they have money to spend, which fuels inflation. The Fed wants to cool that demand without triggering a recession.

James Butterfill, head of research at CoinShares, points to the tension between inflation and employment. He explains that if inflation cools, the Fed gains more room to respond to labor-market weakness. But right now, the labor market is strong enough that the Fed feels it must keep rates high to prevent the economy from overheating. This is a classic balancing act, and the Fed is currently leaning heavily on the inflation side of the scale.

What This Means for You

So, what does a rate hike actually mean for your wallet? It means that if you are looking to take out a mortgage, a car loan, or a credit card balance, your borrowing costs are likely to rise or stay elevated. For savers, it is a bit of a silver lining, as higher rates translate to better yields on savings accounts and bonds. But the real impact is on the cost of money across the entire economy.

The Fed's moves are designed to slow down the pace of economic activity just enough to bring prices back down. It is not a punishment, but a corrective measure. By making credit more expensive, the central bank aims to reduce demand, which in turn puts downward pressure on prices. This is the economic mechanics at play, and it is why the Fed is willing to accept a slower economy in exchange for price stability.

Looking Ahead

As we approach the October 27-28 meeting, the market is watching for any signals from Fed Chair Kevin Warsh. He has stated that he does not prejudge monetary policy decisions, leaving markets without a clear direction. This neutrality is a double-edged sword, as it keeps the market guessing and adds to the volatility.

The next few months will be critical. If inflation continues to resist the downward trajectory, we could see further hikes, as UBS predicts. But if the labor market weakens, the Fed may be forced to pivot. For now, the message from the central bank is clear. They are committed to bringing inflation back to 2% in a timely manner, and they are willing to keep rates higher for longer to achieve that goal. This is the reality of the current economic landscape, and it is one that every investor and consumer needs to understand.
