Key points
-
With inflationary pressures starting to rise in the US the global investment cycle is starting to get more mature. This is likely to mean a further rise in bond yields and more share market volatility.
-
However, there is still little sign of the sort of excesses that precede economic downturns, profit slumps and major bear markets suggesting that we are still not at the top in the investment cycle. Key to watch for will be: over investment, rapidly rising inflation above target and tight monetary policy.
Introduction
The long and strong US bull market

This makes it the second longest since World War Two and the second strongest in terms of gain. And according to the US National Bureau of Economic Research the current US economic expansion is now 104 months old and compares to an average expansion of 58 months since 1945. This naturally begs the question whether recession is around the corner leaving the US and hence global shares vulnerable to a major bear market?
The investment cycle is maturing

A typical cyclical bull market in shares has three phases: scepticism – when economic conditions are weak and confidence is poor, but smart investors see value in shares helped by ultra-easy monetary conditions; optimism or the “sweet spot” – when profits and growth strengthen and investor scepticism gives way to optimism while monetary policy is still easy; euphoria – when investors become euphoric on strong economic and profit conditions, which pushes shares into clear overvalued territory and excesses appear, forcing central banks to become tight triggering an economic downturn, which combines with overvaluation and investors being fully invested to drive a new bear market.
Typically, the bull phase lasts five years. However, “bull markets do not die of old age but of exhaustion” – their length depends on how quickly recovery proceeds, excess builds up, inflation rises and extremes of overvaluation and investor euphoria appear.
This process has taken longer than normal following the GFC because periodic crises or aftershocks from the GFC – eg, the 2010-2012 Eurozone sovereign debt crisis and the 2015-16 global growth scare both of which were associated with mini bear markets globally and 19% and 14% falls in US shares respectively. This combined with post GFC consumer and business caution have prevented the global economy from overheating and excesses building and share markets going into euphoria, that then sets the scene for the next major bear market.
However, this is starting to change. Global growth forecasts have stopped being revised down and are now being revised up. Global growth this year and next will likely be around 3.9% which is above potential. So global spare capacity is starting to be used up.

Not at the top yet
- overall private sector debt growth is modest in most countries (except for corporate debt in the US and China);
- while investment is starting to pick up globally, there is no sign of overinvestment. While the US is further advanced, even here business investment (excesses in which preceded the tech wreck) and residential property investment (excesses in which preceded the GFC) are around their long-term averages relative to GDP.

- capacity utilisation is rising and inflationary pressures are building in the US but inflation is not a problem yet and it’s not an issue in other major countries. Core inflation in major countries ranges between 0.3% in Japan to 1.5% in the US.
