How the world ran out of semiconductors

There’s a global shortage in semiconductors, and it’s becoming increasingly serious. The US is currently reviewing of its supply of the technology, following a landmark executive order from President Joe Biden.

The president also pledged US$37 billion (£26 billion) to cover the short-term costs of rebuilding and securing America’s supply of semiconductors, which are a fundamental part of microchips and thus integral to everything from computers to smartphones to renewable energy and military hardware.

The automotive sector has been worst affected by the drought, in an era where microchips now form the backbone of most cars. Ford is predicting a 20% slump in production and Tesla shut down its model 3 assembly line for two weeks. In the UK, Honda was forced to temporarily shut its plant as well.

Even highly experienced tech companies such as Nvidia and Microsoft are struggling to provide a steady stock of graphics cards and Xboxes respectively. It appears that no company, big or small, tech or non-tech, is safe from the wide-ranging impact of the great semiconductor famine of 2021.

The concentration problem

While it is easy to blame the COVID-19 pandemic for this situation, the truth is that the global semiconductor supply chain had this coming for some time. As much as 70% of the world’s semiconductors are manufactured by just two companies, Taiwan Semiconductor (TSMC) and Samsung.

The entry barriers into semiconductor manufacturing are astronomically high. There’s a steep learning curve required to set up a semiconductor foundry, entailing an upfront investment of US$10-$12 billion and then at least three years to become production-ready.

Even then, there are no guarantees that a new foundry’s chip yields will match those of the incumbents. Chips rapidly become obsolete and price pressures are a major problem in the tech sector, so there are lots of risks to profitability.

Due to such harsh economics, it has only made sense for a handful of large players to invest in manufacturing capabilities and then spread those costs and risks across hundreds of thousands of customers. Global tech has historically been very happy to hand the manufacturing reins to TSMC and Samsung. And in turn, this has created the supply-chain equivalent of a house of cards.

High demand

The pandemic has driven unexpectedly high demand for home electronics such as laptops and gaming consoles, as many people started working from home and seeking more sources of indoor entertainment.

Automotive companies had been expecting lower demand, given that car sales tend to move lower in an economic downturn. This, however, proved to be an erroneous assumption, as new car sales started bouncing back quickly by the tail end of 2020. Automotive companies tried to re-book previously cancelled semiconductor orders only to discover that home electronics manufacturers had taken their place.

At the same time, President Trump’s trade war with China led to new rules that made it harder for Chinese companies to source semiconductors from TSMC and Samsung. With China’s own semiconductor technology inferior to the industry leaders, Chinese tech behemoths like Huawei stockpiled semiconductor chips in advance of the new restrictions in 2020, soaking up any spare capacity with large orders.

But the straw that finally broke the proverbial camel’s back was the sharp rise in bitcoin prices in early 2021. This increased the demand for the graphics processing units that are traditionally used in mining the digital currency, exacerbating the semiconductor supply issues further.

All of this has been enough to cause TSMC and Samsung to run out of capacity and significantly increase lead times to fulfil orders, leading to the drought we see today.

Who loses

The share prices of TSMC and Samsung have risen by 190% and 61% respectively in the past 12 months thanks to the supply shortfall. Despite President Biden’s best efforts, the situation is unlikely to improve in the next three years because of all the barriers to entry in this sector.

Prices of consumer electronics have shot up, thanks to scalpers who routinely buy graphics cards and consoles at recommended retail prices and sell them for higher prices on sites like eBay.

It is only a matter of time before tech manufacturers and retailers decide to increase prices to match the high demand and low supply of the components. Expect to see releases of more expensive variants of existing electronic products hitting the market soon.

Just like in an actual famine, the end consumers of these goods are going to be significantly worse off, with little or no respite coming their way.

EXTRACT: ".... ruminants belch and fart methane, an extremely potent greenhouse gas. As a result, rearing beef cattle brings about, on average, six times the contribution to global warming as non-ruminant animals (for example, pigs) producing the same quantity of protein. ..... if projected to 2050 [beef production], would use 87% of the total quantity of emissions that is compatible with the Paris climate agreement’s objective of staying below a 2° Celsius increase in temperature."

EXTRACT: " .... while China’s leaders never mention it, they are just as embittered over Russia’s theft of Chinese territory in the nineteenth century as they are over the West’s imperial predations. With Western imperialism having been largely rolled back, it is Russia’s continued occupation of historic Chinese territory that stands out the most to ordinary Chinese observers. For example, the city of Vladivostok, with its vast naval base, has been a part of Russia only since 1860, when the tsars built a military harbor there. Before that, the city was known by the Manchu name of Haishenwai." ---- "There is also a demographic argument for Putin to consider: the six million Russians spread along the Siberian border face 90 million Chinese on the other side. And many of these Chinese regularly cross the border into Russia to trade (and a good number to stay)."

EXTRACTS: "According to a new analysis by researchers at Brown University, America’s two-decade war in Afghanistan cost it nearly $2.3 trillion. Now, Afghanistan’s neighbors – Pakistan, Iran, China, India, and the Central Asian countries – are wondering just how much it will cost them to maintain security after the United States is gone." ----- "After clandestinely supporting the Taliban as a means to undermine the US war effort, Russia now fears broader destabilization in Central Asia and beyond." ---- "Similarly, after having made nice with the Taliban, China also now fears the greater regional instability that the US withdrawal may incite. In addition to disrupting Chinese President Xi Jinping’s Eurasia-spanning Belt and Road Initiative, a revitalized Taliban could re-energize the Islamist extremist threat in China’s western Xinjiang province."

EXTRACT: "When former Fed Chair Paul Volcker hiked rates to tackle inflation in 1980-82, the result was a severe double-dip recession in the United States and a debt crisis and lost decade for Latin America. But now that global debt ratios are almost three times higher than in the early 1970s, any anti-inflationary policy would lead to a depression, rather than a severe recession. ---- Under these conditions, central banks will be damned if they do and damned if they don’t, and many governments will be semi-insolvent and thus unable to bail out banks, corporations, and households. The doom loop of sovereigns and banks in the eurozone after the global financial crisis will be repeated worldwide, sucking in households, corporations, and shadow banks as well. ---- As matters stand, this slow-motion train wreck looks unavoidable."

EXTRACT: "Xi Jinping’s call for friendship gives us an opportunity to examine Chinese politics on both the domestic and international stage. On the face of it, it suggests the possibility of rapprochement between the rich liberal democracies represented by the G7 and the authoritarian Chinese state. However, despite appearances of a call for a closer relationship, there is more than one way of being friends – and Xi’s idea might be somewhat different to what many in countries attending the G7 might expect."

EXTRACT: "China’s recently published census, showing that its population has almost stopped growing, brought warnings of severe problems for the country. “Such numbers make grim reading for the party,” reported The Economist. This “could have a disastrous impact on the country,” wrote Huang Wenzheng, a fellow at the Center for China and Globalization in Beijing, in the Financial Times. But a comment posted on China’s Weibo was more insightful. “The declining fertility rate actually reflects the progress in the thinking of Chinese people – women are no longer a fertility tool.” "

Ambition: to be a doctor ...... Favorite sport: football ...... Favorite hobby: making people laugh ...... Death: by mutilation ...... Last words: the UN are coming to save us ----- In his idealism and innocence, David believed the international community would save him and his mother. We didn’t. "

EXTRACT: " While many conservative Republicans opposed Trump and saw that he posed a danger to their party and democracy itself, they were hesitant to buck the mass movement they had created, fearing that it would turn against them. Some of these same conservatives assumed that with Trump's defeat, the horror of January 6th, and the former president's banishment from social media, the time had come to restore sanity to their party. But the GOP leadership’s continued cowering in the face of what they now call "Trump's base" has caused them to circle the wagons and purge their ranks of those who call for sanity. "

EXTRACT: "Netanyahu claims to be acting in the name of the Jewish people. He certainly is not. Many Jews around the world, including me, despise Netanyahu’s racist politics. As an American, I am also deeply troubled by the US government’s knee-jerk support of Israel. Fortunately, I am not alone in this view. A growing number of Democratic Congressmen, Jews and non-Jews alike, have called on the United States to stop supporting Israel’s lawlessness. The truth is that the US government’s uncritical support for Israel has come to depend more on evangelical Christians, such as former US Secretary of State Michael Pompeo, than on American Jews, who are deeply divided by Netanyahu’s actions. And the evangelicals’ real interest in Zionism is not Jews’ security, but Armageddon, the end of the world, which they believe will come only when all Jews are in Israel."

EXTRACT: "While reading Human Rights Watch’s (HRW) monumental report “A Threshold Crossed,” I felt a range of emotions. It also left me with one big question. I was deeply impressed by the report’s rigorous scholarship. At the same time, it brought to the surface feelings of anger and profound sadness. It’s an extraordinarily complete study detailing not only the many ways Israel has violated a broad range of Palestinian human rights, but the ideology of racial superiority and entitlement that Israel has used to justify its repression." ..... "My advice to both Israel’s defenders and weak-kneed liberals is​, “Read the damn report.” "

EXTRACT: "On the face of it, the latest escalation of violence is following the template of all inter-ethnic wars. Muslims observing Ramadan shouted nationalist slogans and clashed with Israeli right-wing groups chanting “Death to the Arabs.” The Israelis haughtily marched with their national flag on Jerusalem Day, marking Israel’s capture in 1967 of East Jerusalem and the Temple Mount, the site of the biblical Second Temple, and of Al-Aqsa, completed in the year 705. Battles in and around the Al-Aqsa compound erupted, with worshipers inside throwing stones at the Israeli police, who responded by firing rubber-tipped bullets and other projectiles, wounding hundreds."

EXTRACT: "Human history, ancient and contemporary, is replete with instances of genocide – that is, the effort to eradicate a people, erase their history, denigrate their culture, and destroy their physical presence. Many of these atrocities have been recognized by the victims and other nations who support them. But, with the notable exception of the German acknowledgment of the Holocaust, rarely have the perpetrators of these crimes accepted responsibility and offer recompense "

EXTRACT: "The best way to defend liberal democracy is to practice it at home and abroad with the “courage and self-confidence” that Kennan touted at the dawn of the Cold War. This is also the best way to ensure the survival of our own conception of human freedom. And survive it will."

EXTRACT: "Ann Arbor (Informed Comment) – Sammy Roth at the LA Times/ Boiling Point Newsletter reports that California’s main power grid was powered for several hours last Saturday by 90% renewables. For just four seconds that day, the grid, which covers 4/5s of the state, reached 94.5% generation by green energy. California is the world’s fifth largest economy. The main grid does not cover Los Angeles County. On the other hand, these figures do not include the electricity generated by the Diablo Canyon nuclear plant, which is not counted as renewable but which is also very low-carbon."

EXTRACT: "It is no accident that there has been an economic divergence in Central and Eastern Europe. Those countries that have joined the European Union have improved their economic governance, and GDP has begun to converge with Western Europe. Between 2014 and 2019, Hungary, Poland, and Romania grew at an annual average rate of 3.9%, 4.1%, and 4.7%, respectively. Meanwhile, Belarus and Ukraine experienced minimal growth during this period, and Russia’s economy expanded at an average annual rate of just 0.7%. Though Russia had a higher per capita GDP (in terms of purchasing power parity) than Croatia, Poland, Romania, and Turkey as recently as 2009, all of these countries have since overtaken it. Russians today are shocked to learn that they are worse off than Romanians and Turks. Among EU member states, only Bulgaria is still poorer than Russia. With its close proximity to the EU single market, Russia could have had higher growth if it had pursued sound economic policies. Instead,..... "
