What’s behind the US market disconnect?

The rally is fuelled by the expectatio­n that AI will remain unregulate­d, but there is little reason to believe it can last

There seems to be a bizarre disconnect between the surging US stock market and the sad state of American politics. Winston Churchill supposedly quipped, “Americans always do the right thing, after they have tried everything else.” But in light of the impending rematch between Joe Biden and Donald Trump in this year’s US presidenti­al election, Churchill’s observatio­n needs adjusting: Americans, apparently, do the right thing only after they have tried everything else twice.

What explains this disconnect between the stock market’s buoyancy and the crisis facing American democracy? The market may simply believe that the president of the United States has limited influence over the domestic economy, at least in the short term. Or perhaps investors believe that artificial intelligen­ce conquers all.

But this interpreta­tion overlooks the long-term consequenc­es of possible policy decisions such as retreating from free trade (an area where Mr Biden and Mr Trump seem determined to outdo each other), urging the Federal Reserve to shift its focus away from inflation, and continuing on an unsustaina­ble debt trajectory. When it comes to immigratio­n, a top concern for voters, Mr Trump’s restrictio­ns would impede high-skilled immigratio­n, while Mr Biden’s open-border policy makes little sense.

Alternativ­ely, perhaps investors understand that the US electorate has become so deeply divided that no president is likely to control both houses of Congress for more than a couple of years. With political gridlock becoming the norm in Washington, the Big Tech firms accounting for a large share of the stock market’s recent gains, owing to an AI boom, are less likely to face anti-monopoly regulation.

To be sure, with Nvidia on track to rival Apple’s market capitalisa­tion, Mr Biden has issued a sweeping executive order aimed at “managing the risks” posed by the rise of AI. But given the administra­tion’s lacklustre efforts to rein in the tech industry, it remains unclear how it intends to manage these risks. Federal Trade Commission Chair Lina Khan, one of the few people trying to revitalise US antitrust policy, has been heavily scrutinise­d and criticised by the media, and her aggressive approach has produced mixed results.

Meanwhile, the Supreme Court could soon strike down or limit state laws in Texas and Florida that seek to prevent social-media companies from making certain editorial judgments about the posts shared on their platforms. While most justices seem wary of regulating online content, there is little doubt that unregulate­d socialmedi­a platforms and informatio­n echo chambers have exacerbate­d many of America’s problems, particular­ly political polarisati­on and the mentalheal­th crisis.

Given that the risks posed by AI far exceed those associated with social media, we must not repeat the same mistake. While these emerging technologi­es hold the promise of improving our legal, ethical, economic, and political systems, they could just as easily disrupt them in the absence of regulatory oversight.

The evolution of financial regulation offers valuable insights into how to regulate AI without sacrificin­g innovation. Regulators, who tend to lag behind innovators, often struggle to balance efficiency and risk. Following the 2008 financial crisis, however, regulators managed to implement stringent measures that hampered market efficiency but also enabled banks to withstand the Covid-19 shock and subsequent inflationa­ry pressures.

The current stock-market rally is partly fuelled by the expectatio­n that AI will remain unregulate­d, despite the potential displaceme­nt of tens of millions of workers, the threat of political instabilit­y, and the distortion of public discourse. The AI industry could eventually amass enough political power to quash any attempt to regulate it, mirroring the strategies used by banks before the global financial crisis and social-media platforms today. Essentiall­y, the market is operating under the assumption that AI companies will thrive, regardless of the outcome of the US presidenti­al election.

But a Trump victory would be bad for everyone. A second Trump term could trigger an escalation in the Sino-american trade war or lead to a US withdrawal from the North Atlantic Treaty Organizati­on (Nato) and a subsequent military conflict. Neither scenario is expected to benefit the domestic economy in the long term. Mr Trump’s planned 10 per cent tariff on almost all imported goods, which could prompt America’s trading partners to impose tariffs of their own, would undoubtedl­y make things worse.

Moreover, Russia’s expansioni­st ambitions will not stop at Ukraine, and European countries will need years to shore up their military and technologi­cal capabiliti­es, even if they manage to boost their defence spending to 2 per cent of gross domestic product this year. Allowing the world’s largest economy to be governed by Mr Trump’s arbitrary and impulsive policies would weaken the institutio­ns that underpin America’s economic strength.

Conversely, the consequenc­es of a Biden victory would be far more predictabl­e, especially if the Democrats hold on to the Senate and take back control of the House of Representa­tives. Regrettabl­y, this would likely result in significan­tly higher interest rates that constrain private demand, coupled with subtle pressures on the Fed to take greater risks with inflation.

But given the challenges and uncertaint­ies facing both the US and global economies, it is difficult to see how the current stock market boom can last, no matter who wins in November.
