Neoliberal

The law may have unintended consequences, too. Chip firms which accept state aid are barred from expanding manufacturing capacity in China. Besides crimping the desire of firms like tsmc and Samsung, which have plenty of Chinese customers, to invest more in American fabs, such rules are prompting Chinese chipmakers to invest in producing less fancy semiconductors. The hope is that lots of older-generation chips can do at least some of what fewer fancier ones are capable of.

According to semi, an industry research group, in 2019 China made about a fifth of “trailing-edge” chips, which go into everything from washing machines to cars and aircraft. By 2025 it will produce more than a third. In July nxp Semiconductor, a Dutch maker of trailing-edge chips, warned that excessive supply from Chinese firms is putting downward pressure on prices. In the long run, this could hurt higher-cost Western producers—or even drive some of them out of business. In July Gina Raimondo, America’s commerce secretary, acknowledged that China’s focus on the trailing edge “is a problem that we need to be thinking about”.

Hardest to predict is the chips Act’s effect on the semiconductor industry’s notorious boom-and-bust cycle. Usually chipmakers would be boosting capacity at a time of rising demand. Right now the opposite is true. Pandemic-era chip shortages have been replaced by a glut, now that consumers’ insatiable appetite for all things digital appears, after all, to be sated. tsmc’s sales declined by 10% in the second quarter, year on year, and the company now expects a similar drop for the whole of 2023. Intel’s revenue was down by 15% in the three months to June, compared with a year earlier. Samsung blamed a chips glut for its falling revenues and profits. Intel’s share price is half what it was at its recent peak in early 2021.

Chip executives point out that prospects for their industry remain rosy. They are probably right that demand is bound to revive at some point. Yet “inventory adjustments” (reducing oversupply, in plain English) are taking longer than expected. And when inventories finally adjust, the business that emerges may be less lucrative. Since early 2021 Intel, Samsung and tsmc have lost a third of their combined market value, or nearly half a trillion dollars. A few more anniversaries may be needed before the chips Act’s impact on American economic security can be properly evaluated. Investors are already making up their minds.
