Broad money growth (M3, Shadow Government Statistics) in the US keeps on decelerating since the end of 2015. As reported in the latest Monthly Monetary Update (Institute of International Monetary Research, IIMR), ‘In the final quarter of 2016 US M3 grew at an annualised rate of 2.2%. This follows on from a mere 0.9% in the three months to November, the slowest annualised quarterly growth rate in over five years. 2016 ends with US broad money growing at an annual rate of 4.0%, which is respectable, but down on 2015’s figure of 4.3%. In mid- 2016, the figure was 4.5%. The subsequent slowdown in broad money growth has been primarily caused by “quantitative tightening” ‘.

What is ‘Quantitative Tightening’? As stated in the IIMR’s January money update cited above ‘ (…) “quantitative tightening” (i.e., the reversal of quantitative easing) when it allows its stock of asset-backed securities to run off at maturity. The Fed can use proceeds from the maturing ABSs to reduce its cash reserve liabilities to the banks rather than to finance new, offsetting purchases of securities.’ (See the January Monetary Update, IIMR). What we do not know yet is whether the Fed has intentionally pursued such a monetary contractive policy, or rather it is just the (indeed surprisingly unnoticed) consequence of the fall securities in its balance sheet when they reach maturity. As far as I know the Fed has not made a public policy announcement in this regard nor committed to such policy.
Why does this matter? Well it does matter when the medium to the long term correlation between money growth and nominal income is acknowledged. Of course it is not a mechanical or a one-to-one correlation, and indeed time lags should be taken into account; anyhow in an environment where the demand of money is fairly stable, changes in the rate of growth of money do translate into changes in nominal income. Table below shows such empirical relation in the US in the last five decades:

Thus should this weakening in money growth in the US continue in the next quarters it will most likely have an impact on economic growth forecasts. This is subject to several caveats though; the new US administration has already announced a profound change in bank regulation which may well ease the pressure put in the midst of the Global Financial Crisis on small and medium size banks particularly to expand their balance sheets. If this materialises in the near future, the creation of more bank deposits in the economy could offset the monetary contractive policy followed by the Fed in the last few months, intentionally or not.
