Analyst Malcolm Penn of Future Horizons is predicting high prices and chip shortages in 2021 with a semiconductor capacity crunch as the market is set to grow significantly by 18 percent. 

Chip supply is effectively sold out for the whole of 2021 as little new capacity will come online before 2022, he says, something that automobile makers are finding to their cost.

Penn has consistently argued that the state of the semiconductor industry always depends on four factors: global GDP; IC manufacturing capacity; the number of units produced; and average selling prices. These are what he calls the four horsemen of the semiconductor apocalypse. One of those – global GDP – fell of his horse in 2020 with the Covid-19 pandemic but for once it did not cause the customary slow-down in the semiconductor industry.

 

Conventionally a crash in the world’s GDP such as happened in 2020 – a fall of 4.4 percent – would be the indicator of a severe recession in multiple fields of endeavour and almost guarantee a subsequent fall in the chip market. But this time some industries stayed strong and 4.4 percent collapse in GDP accompanied a 7.3 percent growth in the semiconductor market. “It has happened before, but only about three times,” observed Penn, speaking in an on-line virtual version of the Future Horizons’ industry forecast seminar.

With GDP set to be 5.2 percent in 2021 the V-shaped nature of the business impact of the pandemic is clear, said Penn. The recovery will be strong in Europe and the UK partly because they, with their exposure to automotive and industrial sectors, suffered the worst with GDP contractions in 2020 of 8.3 and 9.8 percent respectively, he said. This will lead to further chip shortages, he says.

Next: Capex takes time to impact


Penn pointed out that some top line capital expenditure budgets recently announced for 2021 are eye-wateringly large amounts for individual companies – up to $30bn from Samsung and $28bn from TSMC (see US fab part of TSMC capex surge to $28 billion). But added that overall the industry needs to spend $80bn to be in-line with the long-term average of 15 percent of sales, which is the new normal.

With both leading-edge and more mature manufacturing processes the industry has underspent in recent years and as a consequence is now sold out. This partly reflects the diminishing influence of IDMs and the growing importance of foundry manufacturers and their concentrated and tighter control. 

Recoveries in ASPs tend to be slow argued Penn which means that alongside sold-out manufacturing capacity, prices will get jacked up by vendors gradually, bringing the growth in the market. “2019 saw the start of the cyclical ASP recovery. Watch for the graph to turn up in 2021,” he said.

This all led to Penn giving his ‘bull’, ‘bear’ and ‘Goldilocks’ forecasts for 2021.

Penn said the semiconductor market will grow an annual basis by between 11 and 24 percent with 18 percent as the most likely figure. Given the limited ability to expand capacity in the short-term the market increase will driven by shortages of supply and rising chip prices, particularly in the second half of the year. This is a long way above the forecast of World Semiconductor Trade Statistics (WSTS) from December 2020.

There are some caveats Penn puts forward that might reduce or change the numbers. There is still a lot of uncertainty in the world: not least in the tension between an incoming US administration and China; uncertainty in the economics and the unwinding of the fiscal support provided during lockdown. Finally, there is the uncertainty around delays or hiccoughs while returning to post-pandemic normality. Any of these could have a negative or in some cases a positive impact.

But Penn concluded apart from the economic uncertainties the other factors – horsemen – are all strong. The balance of risks to semiconductor growth are more on the upside than the downside, he said.

And whatever, is achieved in 2021 will probably be exceeded in 2022, Penn added. “But don’t worry; it’ll crash in 2023! Because that will be the end of supercycle.”
