Money supply growth rose in August, rising to the highest rate recorded since March of this year. Overall, money-supply growth remains well below the growth rates experienced from 2009 to 2016, and has fluctuated very little since March.

In August, year-over-year growth in the money supply was at 4.8 percent. That was up from July's growth rate of 4.1 percent, and was also up from August 2017's rate of 4.2 percent.

The money-supply metric used here — the "true" or Rothbard-Salerno money supply measure (TMS) — is the metric developed by Murray Rothbard and Joseph Salerno, and is designed to provide a better measure of money supply fluctuations than M2. The Mises Institute now offers regular updates on this metric and its growth.

This measure of the money supply differs from M2 in that it includes treasury deposits at the Fed (and excludes short-time deposits, traveler's checks, and retail money funds).

M2 growth rose slightly in August 2018, rising 4.1 percent, compared to July's rate of 3.9 percent. M2 grew 5.3 percent in August of last year. Like Like the TMS measure, the M2 growth rate has fallen considerably since late 2016, but has varied little in recent months.

Money supply growth can often be a helpful measure of economic activity. During periods of economic boom, money supply tends to grow quickly as banks make more loans. Recessions, on the other hand, tend to be preceded by periods of falling money-supply growth.

Many factors contribute to these trends. In recent months, money supply growth — in both M2 and TMS — has likely been impacted by falling growth rates in real estate loans at commercial banks. In August, real estate loans grew 3.3 percent, year over year, which was a 44-month low. The demand for mortgage loans has softened as mortgage rates have risen. In August, the 30-year, fixed average mortgage rate reached 3.55 percent, which was near a seven-year high:
