Global growth lift good for shares but watch valuations

Monetary policy remains accommodative

The US Federal Reserve has commenced an upward interest rate path but monetary policy is still supportive of economic conditions. Rates will be constrained to only a gradual upward path by the mildness of economic growth and high indebtedness of corporates and government which exaggerates the impact of higher rates on investment and spending decisions.

Rates are accommodative until real rates (that is, after inflation) turn positive. With core PCE inflation now 1.8%, the real Fed funds rate is around -1%. Two or possibly three further rate hikes are likely this year. A more neutral Fed funds rate will not be reached until at least March next year.

The US Federal Reserve is yet to decide how it will go about reducing the size of its balance sheet. It is likely to move very slowly to avoid financial market disruption of the type experienced in the ”taper tantrum” of 2013 when reductions to asset purchases were first flagged. The likely initial move is to reduce the value being reinvested once bonds mature from early next year.

In Europe, underlying inflation has modestly lifted, but at 0.9% remains below the European Central Bank (ECB) target of 2%. Highly expansionary monetary policy will persist for some time yet. In Japan, monetary stimulus including asset purchases will continue to target low lending rates while reducing the funding costs of fiscal measures.

 

Key drivers of growth are in the slow lane

No matter the extent of the short-term bump from fiscal action, subdued longer term US economic growth appears to be predetermined. We expect 2.1% per annum growth over the next five years, which despite being above most western world economies is modest by historic standards.

There are two key drivers of real GDP growth: labour force expansion and productivity gains. In the last 30 years, the average annual growth rate in the US labour force over each five-year period declined to around 0.7% per annum from 1.8%. The current economic expansion has allowed some recovery. The US Bureau of Labor Statistics projects just 0.5% per annum growth in the US labour force to 2024 to 163.8 million people.

The two main factors weighing on labour force growth are declining workforce participation and the aging population. Workforce participation has declined to 63% from 67% in year 2000. Female participation has been modestly declining since 2000 after boosting labour market growth through the 1970s and 1980s. Male workforce participation has been in steady decline since 1960.

Baby boomers are now beginning to exit the workforce. The World Bank expects the proportion of the US population that are 60 years or older to rise to 26.1% in 2030 from 20.7% in 2015. As the population ages, more people drop out of the workforce. Healthcare and social assistance sectors should contribute the most to job growth, offset by declines in manufacture, federal government and agriculture.

US unemployment is now at a historically low 4.5%. While the labour market is getting tighter, there are factors allowing an extended period of employment growth while fuelling only mild wages inflation. Participation amongst the working age population (25-54 years) has increased since mid-2015 and there is scope for this to continue. Underemployment should also continue to fall as new full time positions become available. Underemployed people have work but not as much as they would like.

US policy changes including tighter immigration restrictions could further weigh on labour force growth, reducing the administration’s ability to achieve its economic growth goals.

The other key component of GDP growth, productivity, has also declined. Productivity growth has averaged 1.5% per annum since 1947 but has reduced to just 0.4% on average over the past five years.

Why productivity is so low is hard to pinpoint. It is reasonable to expect some improvement as capital expenditures rise with improved business confidence. US private investment as a percentage of GDP is below the long term average, and this is restricting potential productivity improvements.

Ultralow interest rates in recent years have encouraged companies to buy back stock instead of investing. This trend could reverse as rates drift higher over the next few years. Investments in productive infrastructure could also help lift productivity. A cut to tax rates would help boost activity in the first year but is unlikely to help much beyond that.

In any case, several more structural factors are likely to constrain productivity levels below the long term historical growth rate. Innovations in recent years have been less transformative than the electrification, automobile and wireless communications breakthroughs in the 20^th century. Recent developments such as smartphones, the so called “sharing economy” and various medical advances are yet to be fully monetised. Aging demographics also reduces potential consumption except for various healthcare and financial services.
