Ever since global inflation started heading north at an alarming rate, much of the conventional wisdom on the causes of this trend has pointed to energy prices, especially gas, oil and petroleum prices, says Dr Roelof Botha, economic adviser to the Optimum Investment Group.

Also, when analysing the composition of the basket of goods and services that form the basis for the calculation of the consumer price indices (CPIs) in South Africa and most of its key trading partners, these prices certainly stand out, as do some food prices, he adds.

However, when comparing the upward phase of the commodity price cycle during the first six months of the year with the previous surge in prices that was recorded between 2011 and 2013, it becomes clear that oil is not the culprit.

Rather, it is the cost of shipping commodities such as oil, petroleum and all other traded goods from one port to another that is to blame, notes Botha.

“Oil from Saudi Arabia has to travel almost 10 000 km before it reaches the Port of Cape Town.”

Logistics data tracked by the United Nations Conference on Trade and Development indicates that the oceans carry more than 80% of the world’s traded goods by volume and 70% by value, most of which sail inside 40-foot-long steel containers.

There are dozens of container ships that are the length of four soccer fields and the world’s largest one, the Ever Alot, is the height of a 22-storey building and can carry 240 000 t of cargo.

The ongoing supply chain disruptions caused by the Covid pandemic and now exacerbated by the Russian invasion of Ukraine have provided a stark reminder of the strategic economic importance of the maritime container trade, says Botha.

“The lockdown restrictions induced by the pandemic not only blocked supply chains in ports around the globe, but also did so in an errant manner.

“When one port reopened, some of its destination ports had been closed and this pattern kept on repeating itself for the better part of two years.”

Since the gradual demise of harsh lockdowns, pent-up demand from economic stimulus programmes was simply too much to handle.

The results were fairly predictable, namely long delays in getting goods to customers and an increase in the cost of getting them shipped.

However, the extent of the cost increases caught the whole world by surprise, says Botha.

Ultimately, too few ships and an explosive recovery of demand conspired to send freight costs into orbit, with the Statista Freight Rate Index (SFRI) increasing from $1 262 a container during the third quarter of 2019, to $10 362 in the third quarter of 2021 – an unheard-of increase of 721%.

The cost of shipping bulk commodities spiked even more, notes Botha.

Research by the International Monetary Fund (IMF) shows that the inflationary impact of these higher shipping costs is not likely to recede before the end of the year.

A little bit of good news is the fact that shipping costs have come down since the fourth quarter of 2021, with the SFRI standing at $7 051 at the end of June this year.

Research by the IMF confirms that the trend of rising shipping costs has affected inflation in some countries more than others, says Botha.

In general, countries with a high import propensity and a relatively high trade deficit are bound to witness larger increases in inflation, while landlocked countries and low-income countries are also likely to see a higher turning point for their respective CPIs.

This correlation provides a hint to South Africa’s current CPI, which is significantly lower than that of many of its key trading partners, notes Botha.

South Africa is classified as an upper-middle-income country and has experienced record trade surpluses since 2020. Despite a need to enhance their efficiency, the country also has six major commercial ports.

No to Higher Interest Rates
An understanding of the nature and causes of both domestic and global inflation is crucial for the determination of appropriate monetary and fiscal policy responses, says Botha.

The US and most European Union member States have every right to consider stricter monetary policy via higher interest rates, owing to the low unemployment within their borders.

Taking the natural rate of unemployment into consideration (such as postgraduate students, people on sabbatical and parents of new-born children), the US boasts virtual full employment of its economically active population.

Unfortunately, South Africa is not in such a fortunate position, with one of the highest unemployment rates in the world, although it should be noted that labour market data in many developing countries with large-scale unemployment are not reliable, explains Botha.

“It follows, therefore, that raising interest rates at a time when there is still slack in many economic sectors is a futile and reckless exercise,” he argues.

“The low level of capacity utilisation in manufacturing and the absence of real growth in private-sector credit extension represent two of a multitude of reasons why the Reserve Bank’s Monetary Policy Committee is currently committing economic sabotage and why the recent progress with new formal job creation may now be stopped in its tracks.”
