Tariffs, Deficits and the Fed: A Voter's Guide to What the Election Means for the Dollar

A week before Election Day, currency traders are doing something voters rarely do: reading campaign platforms line by line to figure out what they mean for the dollar. Neither candidate has made the currency a headline issue. Yet almost every major promise on the table, from across-the-board tariffs to tax cuts to comments about the Federal Reserve, runs straight through the exchange rate. For anyone trying to understand why markets have been moving the way they have this autumn, it helps to separate those promises into three channels.

The short version is that the dollar is caught between forces that push in opposite directions. Some policies would likely make it stronger in the near term, others would erode confidence in it over time. Which effect dominates depends not only on who wins the White House but on the composition of Congress and on how much of any agenda actually becomes law.

Channel one: trade and tariffs

The most discussed proposal of the campaign is a sharp increase in tariffs, including talk of a universal levy on imports and much higher duties on goods from China. Standard economics says that, all else equal, tariffs tend to strengthen the currency of the country imposing them. Americans buy fewer imports, demand for foreign currency falls, and the dollar rises, partly offsetting the price effect for consumers. Markets saw a version of this during the 2018 to 2019 trade war.

There is a tension here. Supporters of higher tariffs also tend to favor a weaker dollar to help American exporters. The two goals are hard to reconcile, and some advisers have floated ideas for pushing the currency down deliberately, from pressure on trading partners to talk of a new currency agreement in the spirit of the 1985 Plaza Accord. How a new administration would resolve that contradiction is one of the least understood questions of this election.

Tariffs also carry an inflation risk. If import prices rise and inflation expectations drift up, the Fed might keep interest rates higher than it otherwise would. Higher rates generally support the dollar, which would again work against any weak-dollar ambitions.

Channel two: deficits and debt

The second channel is fiscal. Independent budget analysts have estimated that both campaigns' plans would add to federal deficits over the coming decade, with estimates for the Republican platform generally larger because of proposed tax cuts. Federal debt held by the public is already close to 100 percent of GDP, and net interest costs have climbed past what the government spends on defense.

Bigger deficits mean more Treasury bonds to sell. In the short run, that can push up yields and attract foreign capital, supporting the dollar. Over a longer horizon, the concern is different: whether investors keep demanding Treasuries at reasonable prices if debt keeps climbing with no plan to stabilize it. Some of the rise in long-term yields this autumn has been read by analysts as a partial repricing of that fiscal risk, although rate expectations and strong economic data also played a large role.

Channel three: the independence of the Fed

The third channel is the least tangible and possibly the most important. The dollar's global status rests partly on the belief that the Federal Reserve sets rates based on economic data, not on the White House's electoral calendar. During this campaign there has been open discussion of the president having more of a say in monetary policy decisions. Nothing concrete has been proposed in law, and the Fed chair's term runs until 2026, but the rhetoric alone is watched closely by foreign reserve managers.

The dollar's real collateral is not gold or oil but the credibility of the institutions that manage it.

History offers warnings. Presidential pressure on the Fed in the early 1970s is widely seen as one reason inflation took off later in that decade. Emerging markets from Turkey to Argentina have shown more recently how quickly a currency can weaken when a central bank loses its perceived independence. The United States is not in that category, but the direction of travel matters to institutions holding trillions of dollars in Treasuries.

How the scenarios compare

Putting the three channels together gives a rough map of how analysts have been framing the outcomes. It is not a forecast, and actual moves depend heavily on sequencing, Congress and events abroad.

The last row matters more than headlines suggest. A president facing a Congress controlled by the other party has less room to pass tax cuts or restructure institutions, although tariff powers largely sit with the executive branch. That is why traders are watching House and Senate races almost as closely as the presidential contest.

The world is watching too

Abroad, the election arrives just after the BRICS summit in Kazan, where member countries again discussed payment systems that bypass the dollar. Most of those plans remain at an early stage, and the dollar still accounts for well over half of disclosed central bank reserves and a large majority of foreign exchange trades. But sanctions, tariffs and pressure on institutions all feed a quiet effort by some governments to diversify, including record purchases of gold by central banks over the past two years.

What to take from it

For the next few weeks, dollar moves will likely be driven by polls, results and the first signals from the winner's team. Over the longer run, the more important questions are whether tariffs become permanent, whether deficits stabilize and whether the Fed remains independent in practice. Those are the channels through which a populist turn in either direction would reshape the dollar system, and none of them will be settled on election night.
