The Warsh Fed is Growing Money Supply at the Fastest Rate since Covid
Money Supply is a very important indicator. It helps show how tight or loose current monetary conditions are regardless of what the Fed is doing with interest rates. Even if the Fed is tight, if Money Supply is increasing, it has an inflationary effect.
One key metric shown below is the “Wenzel” 13-week annualized money supply figure. It was made popular by the late Robert Wenzel who tracked the metric weekly as an indicator for where the economy might be headed. In 2020, the Fed started reporting the data monthly instead of weekly. It should also be noted that Money Supply data can be heavily revised in future months.
Recent Trends
Seasonally Adjusted Money Supply has been growing on a consistent monthly basis since November 2023. The latest month (July) showed growth of $103B which followed a similar increase in June and the May increase of $256B which was the biggest monthly surge since 2021.
Since Warsh has taken the helm at the Fed, the Money Supply has been growing faster than at any period over the last 2+ years. Don’t listen to the words, watch the actions!

The increase in July was 5.5% annualized, which is above the three year trend and slightly below the 12-month trend.

July is typically around 5.5%, so this July came in right in line with history.

Non-seasonally adjusted shows that July (orange bar) was actually negative (note: this data is ahead of the seasonally adjusted data above). The up months have gotten larger and the down months have gotten smaller. Not a good trajectory!

The weekly data still bounces around quite a bit. There were actually three negative weeks in a row which last happened in April.

The “Wenzel” 13-week Money Supply
The late Robert Wenzel of Economic Policy Journal used a modified calculation to track Money Supply. He used a trailing 13-week average growth rate annualized as defined in his book The Fed Flunks. He specifically used the weekly data that was not seasonally adjusted. His analogy was that in order to know what to wear outside, he wants to know the current weather, not temperatures that have been averaged throughout the year.
The objective of the 13-week average is to smooth some of the choppy data without bringing in too much history that could blind someone from seeing what’s in front of them. The 13-week average growth rate can be seen in the table below.
Growth had been on an upswing but has flattened out in the high 5% / low 6% range. It got as high as 7% 7 weeks ago.

The plot below shows how the latest year compares with previous years. You can see how 2026 is stronger than all the recent years. It sits only below 2020 and 2021 which were the Covid years. 2019 is starting to catch up but remains below the 2026 trend for now. All the years since 2021 are well below the 2026 level.
Again, if Warsh was serious about fighting inflation, this number would be moving down, not up!

Inflation and Money Supply
The chart below shows the history of inflation, Money Supply, and Fed Funds. As shown, in 1970 inflation worked with a ~2 year lag compared to Money Supply. Money Supply slowed dramatically in 2023 and 2024 but has been moving back up. Inflation has also been stickier than the Fed would like, but unfortunately, they cannot do much given the large debt load of the US Government and Corporations. Despite inflation staying elevated, even moving up in the recent period, the Fed has no choice but to continue lowering rates.
The inflation rate is at 3.3% which is 30 bps below the Fed Funds rate of 3.6%. The inflation rate has remained above 2% for 5 years now, proving much stickier than anyone originally forecast.
To really bring inflation back down, Warsh and the Fed would need to raise rates much higher than the inflation rate. Unfortunately, the math will not allow for that scenario.

Historical Perspective
The charts below are designed to put the current trends into historical perspective. The orange bars represent annualized percentage change rather than raw dollar amount. You can see that the Money Supply has stayed at a positive and consistent growth level. This is not a good sign if inflation needs to be coming down.

Figure: 9 M2 with Growth Rate
Below shows the 13-week annualized average over history. This chart overlays the log return of the S&P. Mr. Wenzel proposed that large drops in Money Supply could be a sign of stock market pullbacks. His theory, derived from Murray Rothbard, states that when the market experiences a shrinking growth rate of Money Supply (or even negative) it can create liquidity issues in the stock market, leading to a sell off.
While not a perfect predictive tool, many of the dips in Money Supply precede market dips. Specifically, the major dips in 2002 and 2008 from +10% down to 0%. 2022 was highly correlated with a fall in Money Supply and the rebound has corresponded with the big stock market move we saw in 2023 and into 2024.
More liquidity getting pumped into the economy helps explain why the market continues to reach all-time highs despite all the headline risk. With the war still on, oil prices reaching multi-year highs, and a ton of uncertainty, one would expect the market to be under pressure. Sure, it has taken a breather since the recent all-time highs, but it is up substantially over 12 months and only given the last little bit back.
Please note the chart only shows market data through August 3rd to align with available M2 data.

One other consideration is the reverse repo market at the Fed. This is a tool that allows financial institutions to swap cash for instruments on the Fed balance sheet.
Reverse Repos peaked at $2.55T on Dec 30, 2022. Money gushed out from March 2023 to May 2024. The balance now sits close to zero.

Wrapping Up
Bottom line is that the Money Supply is growing faster now than it was at any point post-Covid. Warsh can talk tough all he wants, but if the Money Supply is inflating, prices are going to follow. Warsh has another chance this week at Jackson Hole to talk tough, but the market is going to believe it less and less as more data shows he is doing absolutely nothing to combat rising prices.
