Semiconductors might be the new oil -- and that could make the 2020s the new 1970s.

Back then, the world ran on oil -- and any change in supply had a massive impact on demand. When OPEC embargoed the U.S. in the 1970s, the price of crude rose from about $3 a barrel at the beginning of the decade to $13 a barrel by its end. The U.S. even issued gas ration coupons in 1974.

The spike was good news for $Chevron Corp(CVX.US)$ and $Exxon Mobil Corp(XOM.US)$, which returned roughly 100% and 70%, respectively, in the 1970s, but painful for everyone else, as inflation raged. The S&P 500 and Dow Jones Industrial Average rose just 17% and 5%, respectively, over the decade.

If oil was the necessary component for the 1970s economy, chips provide the same function in the 2020s. They power everything from our computers and phones to our cars and appliances. And, as everyone knows by now, there is a shortage, with delivery times growing to more than 20 weeks, per Susquehanna Financial Group data.

Roughly 80% of all the chips in the world are made in Northeast Asia. Politicians realize how big a problem this is, and they have started to demand local manufacturing, with President Joe Biden introducing a plan for $50 billion in chip research earlier this year. Reshoring any industry, including semiconductors, is a years-long process that requires billions in capital. There will be winners and losers. And if it goes on too long, it will filter into the prices of all kinds of goods.

"Shortages related to rapid upswings in demand could become inflationary...a product more known for steadily declining prices."

The global semiconductor shortage has been a particular thorn in the side of the automotive industry all year. It was supposed to resolve itself by the second half of 2021. But more production cuts announced by $Toyota Motor Corp(TM.US)$ this past week show the problem isn't going away soon. In fact, RBC analyst Joseph Spak argues the shortage could last for years.

Part of the problem is structural, Spak says. Electric vehicles need more computing power, but the auto industry typically relies on older-generation chip technology, where capacity isn't being as readily added by chipmakers. Instead, they prefer to focus on newer, higher-end chips for the consumer electronics industry.

The result: Instead of lines at the gas stations, there are lines at the automotive dealerships. Low new- and used-car inventories have pushed up pricing and contributed to rising inflation. Used-car prices rose about 20% in the first half of 2021, while new-car prices rose about 3%. The rise in used-car prices has started to slow, but new-car price gains are accelerating, rising about 7% year over year in July.

That's not good for consumers, but automakers stand to benefit. Constrained production will lead to persistently low inventories and higher pricing. Companies will sell fewer cars, but that's been offset by higher prices. $Ford Motor Co(F.US)$ and $General Motors Co(GM.US)$ shares are up 43% and 17%, respectively, in 2021, and both still trade for about seven times 2022 earnings.

And that's just the auto industry. The longer the chip shortage goes on, the more prices will rise for all types of products. That will benefit chip makers such as $Intel Corp(INTC.US)$ and $Taiwan Semiconductor Manufacturing Co Ltd(TSM.US)$. Wall Street sees upside in the latter. Some two-thirds of analysts covering the stock rate it Buy, and the average price target implies about a 33% upside.

Don't expect long lines outside RadioShack, but expect the chip shortage to be felt just the same.
