Why despite a global shortage, we expect continued growth in the semiconductor sector

  • 21 May 2021 (5 min read)

A shortage of semiconductors is causing supply chain issues across the globe – but while there could be short-term disruption for some end-users, stronger demand and continued innovation will help stabilize the larger marketplace.

Over the past few months, a lack of supply has caused problems for companies ranging from car manufacturers to consumer electronics companies. Volvo1 and Jaguar Land Rover2 for example warned they have had to suspend production until supply issues are resolved, while tech companies including Apple have also felt the impact3 .

The reason for this shortage is primarily – but not only – the coronavirus pandemic. Global lockdowns, the shuttering of factories, cancellation of orders, and restrictions on transportation hampered semiconductor production and shipping in 2020.

At the same time, there was a surge in demand for many items that use semiconductors – such as home entertainment systems and domestic appliances – as consumers purchased new products or upgraded existing devices while stuck at home. Some households experienced a drop in income due to furlough or unemployment, but others saved money by not spending on commuting and leisure – meaning more cash to spend on things like games consoles and smartphones. The stimulus checks sent to individuals in the US as part of the government stimulus program also drove spending on consumer electronics4 .

As vaccines are rolled out and economies reopen, demand for bigger ticket items such as cars has also recovered5 , exacerbating the shortage.

Demand should support growth

Aside from the pandemic, other factors have contributed to the supply chain issue. Winter storms in the US this year hit Texas – home to several leading semiconductor manufacturers – causing manufacturing plants to be closed to conserve power on the grid for heating homes6 . And a fire at a Japanese factory operated by Renesas – one of the largest suppliers of semiconductors to the automotive industry – led the company to warn it may not be able to fulfil orders7 .

Semiconductor manufacturers have ramped up production where possible to try to keep up with the increased demand – but the chips take time to produce, and capacity cannot simply be added overnight. It typically takes more than three months to build a semiconductor, via a complex process in highly sophisticated factories8 , so manufacturers need to anticipate demand, which was difficult during the pandemic.

These factors combined to create a global shortage of semiconductors – albeit one that is expected to be temporary, with the supply/demand balance starting to normalize as the year progresses and potentially into 2022.

One interesting consideration for investors as a result of the shortage is the potential that producers can exert some pricing power. This could help support earnings growth for these businesses. They may also take the opportunity to increase capacity. Taiwan Semiconductor Manufacturing Company, for instance, recently raised its revenue growth targets for the year and said it would invest more in production capacity on the back of surging demand9 .

Long-term structural trends are driving growth

The industry is showing slow signs of a rebound based on long-term structural trends. Worldwide semiconductor revenue rose to $466.2bn in 2020, a 10.4% increase on the year before, according to research group Gartner10 . Meanwhile the Semiconductor Industry Association said global sales of the chips rose 17.8% in the first quarter of this year compared to the same period the year before11 .

Increased digitalization has gone hand-in-hand with developments in semiconductor technology over the past few years, meaning additional markets for these chips have opened up.

The continued development of new smartphone handsets and software remains a powerful driver for demand, but the pandemic has also accelerated certain trends which are seen as beneficial to the semiconductor industry, for example growing usage of data centers, the Internet of Things and the digitalization of industry.

As well as buying home entertainment devices in lockdown, many consumers purchased new devices to enable them to work more easily from home. With a new hybrid way of working set to be the ‘new normal’ for many employees, this will create additional ongoing demand for semiconductors.

At the same time, the need for social distancing has sharpened interest in the Industrial Internet of Things, where semiconductors are used in machines to communicate, process and analyze data, for instance in factories or warehouses, where the ability to safely meet increased long-term demand is at a premium.

Artificial intelligence used in sectors from industrials to healthcare has also come into renewed focus during the pandemic. This was already a growing trend pre-pandemic and one that we expect to continue. Semiconductor maker Nvidia is one example of a company with a wide range of end markets in this area – from data centers to industrials, to video gaming to autonomous vehicles.

While fully autonomous vehicles are still some way off, the technology is constantly developing. In the near term, net-zero targets from governments around the world are speeding up the transition to electric vehicles. These use semiconductors for a variety of purposes, from batteries to emergency braking systems.

Semiconductors play a central role

This shortage only showcases how semiconductors have slowly become essential these chips are in our daily lives. And more and more, businesses and consumers are becoming ‘connected’, adopting new processes and devices that provide solutions for a myriad of issues, ranging from entertainment to shopping to the energy transition.

The 2020s are expected to be a decade of unprecedented innovation – in which semiconductors will play a central role.
