Thursday should have been an ugly day for bonds.

Instead, Treasury yields collapsed.

September producer prices surged 1.3% in a single month, more than double expectations and the largest increase since March 2022. PPI inflation jumped to 6.3% year over year, up from 5.6% in August. Reuters

This came one day after CPI accelerated to 3.7%.

Two inflation reports.

Two upside surprises.

And the 10-year Treasury yield fell roughly ten basis points to about 5.09%, its biggest one-day decline in more than a year. The dollar fell sharply as well. Stocks recovered from early losses, with the Dow gaining 1.1%, the S&P 500 up 0.3% and even the Nasdaq managing a small gain. MarketWatch

If the market was supposed to be terrified of an inflation-fighting Fed, somebody forgot to tell the bond market.

This Was More Than Gasoline

Energy was responsible for much of the PPI explosion.

Producer energy prices rose 10.8% in September. Gasoline jumped 20.3%. Diesel rose 21%.

That was bad enough.

But underneath those numbers was evidence that the energy shock is beginning to spread.

Food prices rose 1.2%.

Services prices jumped 0.8%.

Transportation and warehousing costs increased 3.4%.

Truck freight costs rose 3.8%.

And the broad PPI measure excluding food, energy and trade services still climbed 0.5% for the month and 5.0% over the past year. Bureau of Labor Statistics

That last number makes it much harder to dismiss the report as gasoline volatility.

The pipeline is showing exactly what we have worried about for months. Expensive oil becomes expensive diesel. Expensive diesel becomes expensive freight. Higher freight costs eventually become higher prices for everything being carried on the truck.

Economists now estimate September core PCE could rise around 0.3%-0.4% for the month and about 3.1% from a year ago, up from 3.0%. Reuters

The trend is not toward 2%.

At least not right now.

Yet October Is Nearly Dead Again

The remarkable part is how little Thursday's report changed the Fed outlook.

October hike odds reached only around 30% after PPI. Then Kevin Warsh spoke overnight from the IMF meetings in Bangkok and they fell all the way back toward 15%. Reuters

That is an extraordinary response to the week's data.

Wednesday:

CPI hotter than expected.

Thursday:

PPI dramatically hotter than expected.

Friday morning:

Markets become less convinced the Fed will raise rates this month.

Warsh did not explicitly promise a pause. He reiterated that the Fed intends to deliver price stability and said he does not prejudge meetings.

But his most important message may have been what he didn't say.

He gave no indication that this week's inflation reports had materially changed his outlook. Warsh described the economy as broadly developing as the Fed had expected in September and referred to last month's quarter-point hike as removing "a dose of accommodation." Reuters

One dose.

Twenty-five basis points.

That is the Fed's inflation campaign so far.

The Market Believes December Will Fix It

The consensus has simply moved the hike down the calendar.

October?

Probably not.

December?

Still roughly a 90% probability.

We have seen this movie before.

A month ago September was uncertain until suddenly it wasn't.

Then October became highly probable.

Weak employment arrived and October collapsed.

Now December has become the new certainty.

There is nothing certain about it.

If employment deteriorates again, oil retreats and economic activity weakens, the same market assigning nearly 90% odds to a December hike could decide by Thanksgiving that Warsh should wait again.

That matters because inflation is not waiting.

The Fed raised rates 25 basis points in September.

It now appears likely to wait at least six weeks.

Perhaps another 25 comes in December.

That would amount to 50 basis points of tightening during a period in which producer inflation has already reached 6.3% and headline consumer inflation is moving higher.

The Fed may ultimately be correct that gradualism is sufficient.

But it is unquestionably a very gradual experiment.

Warsh Identified Another Inflation Problem Himself

One part of Warsh's speech was especially interesting.

He acknowledged that the AI investment boom is hitting the demand side of the economy before the supply-side productivity benefits arrive.

In other words, AI may eventually increase productivity and make the economy more efficient.

Right now it requires data centers, chips, electricity, construction workers, transformers, land and enormous amounts of capital.

That creates demand.

Warsh explicitly acknowledged that this investment surge is putting upward pressure on prices in the near term. Reuters

So we now have at least two major inflationary forces operating simultaneously.

The energy shock from the Middle East.

And an enormous domestic capital-spending boom centered around AI.

Neither is especially sensitive to another 25-basis-point increase in the federal funds rate.

That complicates the Fed's job considerably.

Why Did Bonds Rally?

Thursday's Treasury move initially looks irrational.

Hotter inflation normally means higher yields.

There were several reasons for the opposite reaction.

The weakness in AI-related stocks early Thursday created a flight toward government bonds. Investors were already nervous about the enormous amount of debt being issued to finance AI infrastructure.

More importantly, Fed officials have spent the week convincing markets that they are not eager to respond immediately to the inflation data.

If traders believe Warsh will wait, the short end has less reason to price another October hike.

There is also growing concern that today's extremely high long-term borrowing costs eventually weaken the economy without additional help from the Fed.

The retail-sales report provided a hint.

Headline sales rose a strong 0.8% in September, but gasoline-station receipts surged 6.4% because fuel became so expensive. The retail-sales control group most closely tied to GDP consumption rose just 0.1%. Reuters

Consumers are spending more dollars.

That does not necessarily mean they are buying considerably more stuff.

When part of the increase is simply paying more for gasoline, nominal growth can disguise declining purchasing power.

That may be what the bond market is beginning to notice.

The Dollar Makes the Message Stranger

The dollar's reaction was equally noteworthy.

Only days ago the dollar index reached an 18-month high as investors anticipated tighter U.S. policy.

Thursday it fell about 0.5%, and it continued weakening Friday after Warsh failed to sound alarmed by the inflation numbers. Reuters

That produces a curious policy combination.

Inflation rises.

The Fed signals patience.

Bond yields fall.

The dollar weakens.

A weaker dollar can itself increase the cost of imported goods and commodities.

Lower yields loosen financial conditions.

Higher stock prices loosen them further.

Those are not exactly the conditions one would normally associate with an aggressive inflation fight.

The market seems to believe the Fed will eventually tighten enough to control inflation, while simultaneously betting that it will not tighten very much right now.

That assumption deserves to be tested.

The Real Danger Is the Trend

Any single inflation report can be noisy.

Energy prices are particularly volatile.

September's 1.3% PPI increase will almost certainly not be repeated every month.

That isn't the concern.

The concern is direction.

CPI accelerated from 3.4% to 3.7%.

PPI accelerated from 5.6% to 6.3%.

The underlying PPI measure excluding food, energy and trade services is running at 5.0%.

Core PCE appears likely to move higher.

And oil remains above $100.

That is a collection of numbers moving away from the Fed's target, not toward it.

Yet after the strongest monthly PPI increase in four and a half years, Warsh sounded comfortable enough that markets reduced the probability of immediate action.

That is the real story of the week.

Not whether October ultimately produces another 25 basis points.

The question is whether the Fed is once again responding to an inflation trend only after it becomes impossible to ignore.

By the time several months of higher energy, transportation and producer costs finally work their way through consumer prices, a quarter-point increase in September may look very small.

Another quarter point in December may not look much larger.

The Market Is Betting on a Very Fine Line

For now, investors seem to believe everything works out.

Inflation rises enough to keep December in play.

Employment weakens enough to keep October off the table.

The economy slows enough to bring inflation back down without recession.

Bond yields retreat from their extremes.

And corporate earnings keep stocks near record highs.

Possible.

But Thursday demonstrated how confused the pricing has become.

The hottest PPI report since 2022 produced falling Treasury yields, a falling dollar and rising stocks.

Warsh then looked at an economy with accelerating inflation and said conditions remain broadly in line with what the Fed expected.

Perhaps he is right.

Perhaps September's energy spike begins reversing before it becomes embedded elsewhere in the economy.

But the PPI report contains an uncomfortable warning that the process may already have started.

Freight is rising.

Services are rising.

Food is rising.

Underlying producer prices are rising.

And the Fed's response so far amounts to 25 basis points.

There may be another 25 in December.

At the speed inflation is moving, the risk is becoming obvious:

by the time the Fed stops tiptoeing, it may already be chasing it.
