5 MIN READ - The Cautious Optimism Correspondent for Economic Affairs and Other Egghead Stuff once again visits recent inflation numbers and the media’s repeated attempts to link them to tariffs.

| Ricardo's 1810 Bullion Debates. The media should have checked this first |
Last week we got a slightly elevated July consumer inflation report, up 2.7% year-over-year, and higher than in June and May.
And immediately the press blamed tariffs with headlines like:
” Inflation ticks higher as Trump's tariffs kick in.”
-Politico, August 12th
“Inflation remains elevated as Trump's tariffs take hold.”
-NPR, August 12th
“US wholesale prices jump in July as tariffs hit.”
-BBC, August 12th
Now the Economics Correspondent is generally no fan of tariffs, especially when other countries impose them unilaterally on the United States for decades. But whether you’re pro-tariff, anti-tariff, pro-free trade, pro-mercantilist, or pro-industrial policy, inflation is still a monetary phenomenon and not caused by tariffs (except under a rare set of conditions which we’ll see don’t apply here).
Milton Friedman famously said “Inflation is always and everywhere a monetary phenomenon, in the sense that it is and can be produced only by a more rapid increase in the quantity of money than in output.”
That remains true, and to prove both Friedman right and the “blame Trump’s tariffs” press wrong, let’s take a look at what the media won't: the "monetary phenomenon" of the last year.
As we’ve already covered in previous articles Friedman’s license plate read:
mv=py
That is, money supply x monetary velocity = the general price level x economic output.
There’s nothing about "tariffs" in the formula.
So what happens if, unlike the media, we actually bother to look at the "m" in the equation of exchange: the money supply?
M2 from July 2024 to July 2025 rose by 4.8%, which is entirely within the purview of the Federal Reserve.

I'll repeat both numbers:
Prices rose 2.7%.
The money supply rose 4.8%.
Since the Fed is in charge of monetary policy, since the Fed is tasked with meeting a 2% inflation target, and since the Fed boasts of its independence, then the Fed is far more guilty of the 2.7% inflation report than any alleged effect of tariffs.
For all that was required for the Fed to achieve its 2% year-over-year inflation target was to increase the money supply by a still-forceful 4.1% instead of the too-high 4.8%.
Why doesn’t the press mention this instead?
Part of it is Trump Derangement Syndrome. A bigger part of it is the much longer-standing ignorance of what the Fed actually does plus a tendency by the establishment—the media included—to rally around our central bank as some indispensable institution that bestows us with eternal economic salvation (hint: it's neither).
Now some more sophisticated people might say "Well the Fed has to offset real economic growth to keep prices stable, so of course it has to grow the money supply.”
OK fine. From 2Q24 to 2Q25 real GDP rose by 2%.
https://fred.stlouisfed.org/graph/?g=1LAKs
So if you print 4.8% more money chasing 2% more goods and services, the result is 2.7% inflation (1.048/1.02 = 1.0274), which is exactly the elevated inflation rate we got.
Thus, the original point remains: none of the latest inflation number can be attributed to non-monetary factors, including tariffs.
And again, the Fed printed money too fast. If it had simply printed 4.1% more money instead of 4.8% more money then year-over-year inflation in July, even with offsetting economic growth, would have been its dead on target at 2% (1.041/1.02 = 1.0206).
But then, say the sophisticated Fed apologists, to slow down the rate of monetary growth the Fed would have to raise interest rates which would be really bad, right?
Not when considering an even better solution they don’t mention. Namely, the Fed could have simply never lowered interest rates during the last five months of the Biden administration in the first place (September 2024 to January 2025). Had rates stayed where they had been for the previous year, a full 100 basis points higher, we wouldn't be looking at 2.7% CPI inflation today.
Inflation stood at 2.6% in October 2024 and 2.7% in November 2024. Given its dual mandate of full employment and a 2% inflation target (which the Correspondent believes is already too high), the Fed’s rate cuts made no sense in late 2024, just as cutting rates today with 2.7% inflation also makes no sense.
But then the press wouldn't have a Trump-linked scapegoat to headline.
To repeat: monetary policy is the purview of the Fed. The Fed is not only entrusted with it, Congress has granted it a coercive monopoly over currency, reserves, setting interbank interest rates and interest on reserves (IOR) rates, etc... to carry out its mandates. It has all the tools it needs to achieve any price target it wants.
Former Fed governor and short-list nominee for next Fed Chair Kevin Warsh said exactly this (about the Fed’s toolbox) in his recent Hoover Institution interview.
But the media reports "tariffs, tariffs, tariffs” while remaining silent on the money supply and silent on the Fed.
One more thought that puts this all in historical perspective: The United States was a major tariff/protectionist country in the late 19th century. The post-civil war era was dominated by Republican administrations and Congresses, and in those days the Republicans were a big pro-tariff party and imposed them all throughout.
So if tariffs cause inflation, why then in the golden era of protectionist tariffs was there not only no high inflation, but prices actually ***fell*** by 39% or an annualized inflation rate of -1.0%?

The answer: there was no Fed printing fiat money. And tariffs didn't cause inflation then either.
As we’ve already discussed in earlier articles the effects of tariffs on inflation are like those of oil, with both misunderstood.
When either tariffs or more expensive oil raise the prices of certain goods, especially inputs for other products that get purchased by consumers down the line, consumers ultimately do pay more for them.
But if the money supply remains constant, then those same consumers will have less money left over to buy other products whose prices will necessarily fall due to decreased monetary demand. British economist David Ricardo understood this even in 1810 during the great Bullionist Debates. Knut Wicksell, F.A. Hayek, Milton Friedman and a plethora of other competent monetary economists have understood this basic principle too.
Yet over two centuries later journalists and even many economists continue to promote the tariff or oil “cost-push” fallacy.
Overall with tariffs or higher oil prices there is no inflation in the general price level... unless one of either two things also happens:
1) The central bank prints more money (the actual cause of the inflation)
2) The higher oil prices or tariffs begin to impact output and real GDP suffers by going negative (not the case in the late 19th century and GDP rose 3% in Q2).
Trump's tariffs are not causing inflation. The Fed continuing to inflate the money supply too fast is, but the Fed’s culpability—for the latest inflation report, for 2021 and 2022’s inflation, for the 2008 financial crisis, for the recent housing bubble, and for the last half century’s multiple asset bubbles and boom-bust cycles—is once again ignored by the press.
