Rest of World’s Growth Is at Trump’s Mercy

Donald Trump will retake office in a global economy substantially transformed from eight years ago—one much more reliant on the U.S.

It means that the president-elect’s plans, including across the board tariffs, could pack an even greater wallop on other countries than the first round of “America First” economic policy. It also gives Trump much more leverage in negotiations over trade policy.

Strong growth since the pandemic has expanded the U.S.’s weight in the global economy. Its share of output among the Group of Seven wealthy nations is higher than at any point since at least the 1980s, International Monetary Fund data shows.

Growth in China, the world’s second-largest economy, has slowed. Germany, the largest European economy, is contracting. Many poorer economies are buckling under the weight of high debt.

U.S. gains in global output partly reflect the strong dollar, which pushes up the value of American output relative to that of foreign economies. But they also result from substantial increases in U.S. productivity compared with the rest of the world.

The changes in the global economy have made America, not China, the premier destination for foreign direct investment, enlarging the exposure that foreign companies have to the U.S. economy and changes in government policy. A booming U.S. stock market has attracted huge flows of investment dollars.

“The fact that much of the rest of the world is now struggling to generate demand on its own provides more reason for countries to try to reach some sort of accommodation with Trump,” said Brad Setser , a senior fellow at the Council on Foreign Relations.

Trump started imposing tariffs in 2018, primarily on China but also on Europe and other allies. Those tariffs fractured global trade, weighing on large exporting economies in Asia and Europe, while not obviously hurting the U.S., which is less reliant on foreign demand than its trading partners. Trump campaigned on a promise to impose at least a 60% tariff on China, and an across the board tariff of 10% to 20% on everywhere else.

America’s superior economic performance has been driven in part by energy independence and massive government spending, said Neil Shearing , chief economist at Capital Economics in London. Since the U.S. now exports more energy than it imports—including millions of barrels of oil each month to China—the nation as a whole benefits when energy prices rise, unlike for net importers such as China and Europe.

The upshot: America’s traditional role as the centre of gravity in the global economy has become even more pronounced in the years after Trump’s first-term tariffs, the pandemic, and Russia’s full-scale invasion of Ukraine.

U.S. influence over Europe’s economy is a case in point. The U.S. has cemented its position as Europe’s largest export market as trans-Atlantic trade surged in recent years and China’s imports from Europe stalled. The U.S. has replaced Russia as Europe’s major source of imported energy. Europe runs big trade surpluses with the U.S. but big trade deficits with China.

The result is access to the U.S. market is far more important for Europe than access to European markets for the U.S. That asymmetry will give Trump leverage in trade negotiations with Europe, according to economists.

Germany exports around 7% of its entire manufacturing value-added to the U.S., but Germany imports only around 0.8% of value-added in U.S. manufacturing, according to a September paper by researchers at Germany’s Ifo Institute for Economic Research.

“German business is vulnerable to Trump,” said Marcel Fratzscher , president of the Berlin-based economic research institute DIW Berlin.

Parts of Asia have benefited from the changes in supply chains sparked by Trump’s initial trade war with China. Many manufacturers, including Chinese ones, moved factories to places such as Vietnam and Cambodia. For the past two quarters, Southeast Asia’s exports to the U.S. have exceeded those to China.

But that now leaves them more exposed to across the board tariffs, a policy that Trump advisers say will be necessary to force manufacturing back to the U.S.

To be sure, Trump’s policies could create countervailing forces. Tariffs would decrease imports and potentially weigh on productivity, but tax cuts would drive up household and business spending, including, inevitably, on imports. Other countries could retaliate by placing tariffs on U.S. goods.

Meanwhile, a tight U.S. labor market has pushed up wages, which is good for those workers. But it could pressure employers to raise prices, in turn making them vulnerable to foreign competition.

Many economists are girding for a different type of trade war from Trump 1.0, when trade fell between the U.S. and China but was diverted elsewhere.

“As long as protectionism refers only to one country, China, the world can live with this,” said Joerg Kraemer , chief economist at Commerzbank. “The thing becomes difficult or dangerous if you implement tariffs on all countries. This would be a new era in global trade.”

Happy is the family whose members—parents, grandparents and grown children—trust each other enough to cooperate on shared goals, especially financial ones. When that is truly the case, Uncle Sam’s tax rules can help as well.

This matters especially now that mortgage rates are above 7%, and many families are looking for ways to help younger members. If the elders have resources and are confident younger ones can cooperate, a family loan could make homeownership possible while providing the elders with a useful income stream.

Other strategies can actually lower taxes, such as when funding 529 plans or Roth IRAs, or when someone inherits a traditional IRA with required withdrawals larger than they will need.

Here are three strategies useful for functional families.

Intrafamily loans

It is perfectly legal for families to lend money to a relative for a down payment or even a private mortgage.

But it is important not to cut corners, says Ryan McKeown, a CPA with Modern Wealth Enhancement in Minnesota. If the loan is for a down payment, be honest with the mortgage provider and have a formal agreement. The lender owes tax on the interest payments received.

If the loan is for a private mortgage, both sides should have legal representation with a formal written agreement, including payment terms. The lender owes tax on the interest, and the borrower often can deduct it if he or she itemizes.

To avoid IRS trouble, the interest rate shouldn’t be lower than the agency’s Applicable Federal Rate at the time of the loan. Currently that is about 5% for loans longer than nine years; about 4.5% for loans three to nine years; and about 4% for loans three years or less. Currently, traditional mortgage rates are generally above 7%.

In addition, the lender could use the $19,000 annual gift-tax exemption (described below) to forgive some or all of the interest or principal annually. If both lenders and borrowers are married, that is up to $76,000 a year. There is no tax for the borrower on such forgiveness, because it is from a gift.

If you’re going this route, McKeown advises against having a fixed plan to forgive the debt. Instead, do it in one-off letters specifying the amount—and keep careful records. Otherwise the IRS might try to treat the loan as a taxable gift.

Asset gifts

Powerful tax-saving moves for families often use gift-tax provisions. Under current law, anyone can give anyone else up to $19,000 of assets annually, free of gift tax. That means a married couple with three grandchildren could give them a total of $114,000 in 2026.

The gifts can be cash or other assets, like stock. For noncash gifts, the cost basis—which is the starting point for measuring taxable gain after a sale—“carries over” to the recipient. So if someone buys $1,000 of stock and gives it away when it is worth $5,000, the recipient’s cost basis is $1,000. If the recipient later sells the shares for $8,000, the taxable gain is $7,000.

Here’s an example showing how gifts could save a family taxes. Grandma is a widow of modest means, while her child and spouse have prospered. The couple has two children, and they want to contribute $5,000 to a 529 college-savings plan for each—but they need to sell stock to do it. Their tax rate on the sale would be 18.8%, and they would need to sell about $11,000 of stock.

However, Grandma’s federal tax rate on the stock sale is 0%. If the couple gives $10,000 of shares to Grandma, she could sell them, pay no tax, and fund the grandchildren’s 529 plans. This saves about $1,000 of tax.

These moves are legal, and they could be used in other ways, such as to help a young person fund a Roth IRA.

But trust among family members is essential: Under the law, givers can’t put conditions on a gift. Grandma could use her stock proceeds to take a cruise, but she makes 529 contributions instead.

Mark Sellner, a retired tax attorney and CPA living in Sarasota, Fla., uses this strategy. His children sell stock he gives them and fund 529 plans for his grandchildren.

The family’s tax savings aren’t huge, but he likes other benefits. The sales by his children don’t boost his adjusted gross income, which in turn could raise his Medicare Irmaa premiums or his 3.8% surtax on net investment income.

Sellner doesn’t worry about his children using the funds for another purpose.

“There can’t be any strings attached to gifts. Of course, it is up to us to decide whether to make them in the future,” he says.

Two caveats: The “kiddie tax” applies to most children under age 24, and it is levied at the parents’ rate on investment income above $2,700 in 2026. Consider this before making gifts to a young person.

Investors who give away stock also forgo the step-up, an important provision that exempts assets held at death from capital-gains tax.

Sellner knows he’s losing a step-up, but says, “The children could use a little more now. Why should they wait 20 years to get it?”

Disclaimers

A disclaimer is a highly useful strategy in which one heir renounces an inheritance in favor of another heir. Assuming family members cooperate, this can save taxes.

Here’s one example. Dad died and had a large traditional IRA that he left to Mom. She has enough assets and income to cover her expenses, and she lives in a state with a stiff estate tax. The inherited IRA would put her estate over the threshold.

Also surviving are three young-adult children. If Mom disclaims all or part of Dad’s IRA within nine months of his death, that amount could go directly to the children. They will have 10 years to empty the account, and the family as a whole will likely save estate and income taxes.

Disclaimers have many key details, especially regarding beneficiary documents. Although heirs have great freedom in choosing what assets to disclaim, the rules about who gets disclaimed property are rigid. It is best if the original owner names tiers of heirs so that if one disclaims, the next recipient is clear.
