How Investing Will Change if the Dollar No Longer Rules the World

If you’ve been investing your savings for the past 15 years, there is a situation you’ve hardly ever encountered: the U.S. dollar getting structurally weaker. Given the fallout from President Trump’s “Liberation Day,” you may need to get used to it.

Wall Street was caught off guard when the greenback dropped against major currencies following this past week’s tariff news. Markets feared that protectionism could put an end to the U.S.’s economic dominance since the global financial crisis.

International money managers, who had massively biased their holdings toward U.S. assets, are feeling the urge to find another source of high returns. American investors, long comfortable ignoring foreign stocks, may no longer have that luxury.

“We are working on the assumption that in the next five years, the dollar is going to lose another 10% to 15%,” said Luca Paolini, chief strategist at Switzerland’s Pictet Asset Management.

To be sure, asset managers in many cases are making short-term, defensive moves to protect against a potential recession. It also follows a trend of money leaving the “Magnificent Seven” stocks specifically— Apple , Microsoft , Amazon.com , Alphabet , Meta Platforms , Nvidia and Tesla —for reasons not fully related to Trump .

These companies drove much of the exceptional returns of the past decade and a half, but their collective price/earnings ratio hit a staggering 46 times last December. At such a lofty level, it doesn’t take much for a fall to ensue.

Even excluding the Magnificent Seven, though, Americans who bought the rest of the S&P 500 15 years ago earned a total return of around 380%. Europeans who did the same, unhedged, earned about 490%—thanks to the dollar’s more than 20% gain against the euro, according to FactSet.

The reverse also holds: Eurozone equities returned about 220% in euros, but only 150% in dollars. Japanese equities tell a similar story—the Nikkei 225 gained 300% in yen, but just 160% in dollars. No wonder Americans haven’t rushed to add these stocks to their 401(k)s.

What is striking is that a stronger dollar should, mechanically, hurt U.S. stocks—by reducing the dollar value of overseas earnings—and help foreign ones. Historically, it has been better to buy the S&P 500 when the dollar was weakening. Over the past five years, that held true: Fed rate hikes strengthened the dollar while hurting equities.

But in the seven years before Covid-19, the dollar and U.S. equities moved in sync. That was the heyday of the “American exceptionalism trade,” when U.S. assets outperformed across the board—not just in tech. This included currency-sensitive sectors like industrials.

Two forces helped drive this. One was the fracking boom, which made the U.S. largely energy self-sufficient, cutting corporate costs and turning the dollar into a kind of “petrocurrency.” Investors learned in 2014 the counterintuitive lesson that the U.S. economy may actually suffer when crude prices nosedive, and benefit when they rise.

Indeed, the other factor was that U.S. consumer spending was unrelenting, even at times when gas-pump prices increased. For years, it has been powered by government deficit spending, a tech sector exporting services globally at scale, and the wealth effects from a booming stock market.

Most of that now risks being turned upside down, exposing investors to the prospect of falling equities alongside a weakening currency.

Trump has pledged to plug the budget deficit, which could arguably weaken the dollar. Meanwhile, he has launched a tariff war that has tanked the equity market, triggered retaliation from China and may provoke European blowback against U.S. tech giants.

The new regime could echo the early 2000s, when investors turned against both tech and U.S. stocks in the aftermath of the dot-com bubble. At the time, the dollar also had a positive correlation with equities, as capital flowed into the so-called Brics—Brazil, Russia, India, China, and South Africa.

In a report to clients Friday, Jeff Schulze of ClearBridge Investments noted that international equities have historically picked up the slack when the S&P 500 lagged behind. In such cases, the MSCI EAFE and MSCI Emerging Markets indexes beat the benchmark U.S. index by an annualized average of 2.0 percentage points and 12.1 percentage points, respectively.

A weaker dollar itself helps support the financial resilience of developing nations. Meanwhile, the European Union has rekindled investor hopes that it can close the growth gap with the U.S. through fiscal stimulus, industrial policy and energy independence.

At the same time, this is nothing like the 2000s. The rest of the world is far more exposed to trade than the U.S.’s relatively closed economy and will have to grapple with China rerouting a huge glut of cheap goods there.

Another option for investors, then, is to remain in U.S. equities and hedge the currency risk—but that is expensive—or to broaden exposure to discounted “value” stocks and try to identify potential long-term winners.

An economy reshaped by Trump would imply more investment and less consumption. Since the only profitable way to onshore production—whether a Nike shoe or a General Motors SUV—is to use machines instead of labor, capital goods manufacturers may eventually benefit. But they are also among the hardest hit by today’s indiscriminate disruption to global supply chains.

Given the complete lack of clarity, the only solution for those who still need the long-term upside of stocks may be to do all of it at the same time. Right now, diversification isn’t just a strategy, it is a lifeline.

Former New Hampshire Gov. Chris Sununu delivered a warning to Treasury Secretary Scott Bessent during a recent visit to Washington: Already-high airfares will surge if the war in Iran doesn’t end soon.

Sununu, a Republican who represents some of the biggest airlines as president of the industry group Airlines for America, has for weeks sounded the alarm to Trump administration officials about the economic fallout from high jet fuel prices. The war, Sununu has argued, must come to a close soon, or things will get worse.

Administration officials have gotten the message.

Privately, President Trump’s advisers are increasingly worried that Republicans will pay a political price for the rising fuel costs, according to people familiar with the matter. Many of those advisers are eager to end the war, hoping prices will begin to moderate before November’s midterm elections.

The fallout from the U.S.-Israeli attack in late February has slowed traffic through the Strait of Hormuz, a vital shipping lane, triggering a sharp increase in oil, gasoline and jet-fuel prices.

That means consumers are grappling with high costs ahead of the summer travel season, as they consider vacation plans.

Sixty-three per cent of Americans said they put a great deal or a good amount of blame on Trump for the increase in gas prices, according to a new poll conducted by NPR, PBS and Marist.

More than 8 in 10 Americans said struggles at the gas pump are putting strain on their finances.

Jet-fuel prices roughly doubled in a matter of weeks after the war began, and they have remained high. Airlines have said that will add billions of dollars of additional expenses this year, squeezing profit margins.

U.S. airlines spent more than $5 billion on fuel in March—up 30% from a year earlier, according to government data.

Carriers have been raising ticket prices, hoping to pass the cost along to consumers, and they are culling flights that will no longer make money at higher price levels.

In March, the price of a U.S. domestic round-trip economy ticket rose 21% from a year earlier to $570, according to Airlines Reporting Corp., which tracks travel-agency sales.

So far, airlines have said the higher fares haven’t deterred bookings and they are hoping to recoup more of the fuel-cost increases as the year goes on.

Earlier this week, Trump said the current price of oil is “a very small price to pay for getting rid of a nuclear weapon from people that are really mentally deranged.”

Secretary of State Marco Rubio told reporters that if Iran got a nuclear weapon, the country would have more leverage to keep the strait closed and “make our gas prices like $9 a gallon or $8 a gallon.”

Trump has taken steps in recent days to bring the war to an end. Late Tuesday, the president paused a plan to help guide trapped commercial ships out of the Strait of Hormuz, expressing optimism that a deal could be reached with Iran to end the conflict.

Crude oil prices fell below $100 a barrel on Wednesday, after reports that Iran and the U.S. are working with mediators on a one-page framework to restart negotiations aimed at ending the conflict and opening the strait.

Sununu said Trump administration officials are conscious of the economic fallout from the war: “They get it…and I think that’s why they’re trying to get through the war as fast as they can.”

But he cautioned that it could take months for prices to return to prewar levels.

“Ticket prices won’t go down immediately” after the strait is fully reopened, Sununu said. “You’re looking at elevated ticket prices through the summer and fall because it takes a while for the prices to go down.”

Since the initial U.S.-Israeli attack in late February, Sununu has met in Washington with National Economic Council Director Kevin Hassett, representatives from the Transportation Department and senior White House officials.

A White House official confirmed that Hassett and Sununu have discussed the effect of increased fuel prices on the airline industry. The official said the conversation touched on how the industry can mitigate the impact of high jet fuel prices on consumers.

“The president and his entire energy team anticipated these short-term disruptions to the global energy markets from Operation Epic Fury and had a plan prepared to mitigate these disruptions,” White House spokeswoman Taylor Rogers said, pointing to the administration’s decision to waive a century-old shipping law in a bid to lower the cost of moving oil.

Rogers said the administration is working with industry representatives to “address their concerns, explore potential actions, and inform the president’s policy decisions.”

A Treasury Department spokesman pointed to Bessent’s recent comments on Fox News that the U.S. economy remains strong despite price increases. The spokesman said Treasury officials have met with airline executives, who have reaffirmed strong ticket bookings.

“We’re cognizant that this short-term move up in prices is affecting the American people, but I am also confident, on the other side of this, prices will come down very quickly,” Bessent told Fox News on Monday.

The war has already contributed to one casualty in the industry: Spirit Airlines. Company representatives have said they were forced to close the airline because the sustained surge in jet-fuel prices derailed the company’s plan to emerge from chapter 11 bankruptcy.

The Trump administration and Spirit failed to come to an agreement for the company to receive a financial lifeline of as much as $500 million from the federal government.

Transportation Secretary Sean Duffy has argued that the Iran war wasn’t the cause of Spirit’s demise, pointing to the company’s past financial struggles, as well as the Biden administration’s decision to challenge a merger with JetBlue.

Other budget airlines have also turned to the federal government for help since the U.S.-Israeli attack. A group of budget airlines last month sought $2.5 billion in financial assistance to offset higher fuel costs, and they separately wrote to lawmakers asking for relief from certain ticket taxes.

Should the U.S. currency and stocks no longer rise together, Americans will need to broaden their portfolios.

Administration officials have spoken to the airline industry, which has voiced concerns about the rising costs.
