The US midterms have handed dollar bears a fresh political argument, but I wouldn’t mistake the prospect of congressional gridlock for the beginning of a structural dollar decline. The Fed still holds the monetary cards, while the euro is wrestling with French fiscal baggage and the Aussie has discovered that a rate hike doesn’t count for much when the central bank takes away the promise of another.

Takeaways by Dark Side of the Boom™

• A Democratic sweep could put the dollar on the defensive, although the bigger consequence may be a cap on further upside rather than an outright trend reversal.

• The AI trade has become an increasingly important source of dollar support, leaving the greenback vulnerable to political scrutiny of the technology investment boom.

• The euro has room to benefit from dollar weakness, but stubbornly wide French sovereign spreads are keeping the bulls on a short leash.

• Australia’s rate hike came with a dovish sting, although attractive carry and limited scope for further policy disappointment leave the medium-term Aussie recovery argument intact.

Washington Throws a Wrench Into the Dollar Trade

The US midterms have given currency traders another reason to question the dollar’s upside, although I would be careful about turning a political reshuffle into a grand bearish greenback thesis. Washington may change hands, but the Fed still sets the price of money, and that remains the more important consideration for anyone trading the dollar beyond the immediate election window.

The Democrats entered election day with the House broadly expected to fall into their column, leaving the Senate as the bigger potential surprise. Prediction markets had already assigned roughly a 74% probability to a Democratic Senate victory, but there was still enough uncertainty around the outcome to leave room for a fresh adjustment in FX positioning.

The blue sweep would raise the prospect of greater fiscal gridlock, particularly around government funding, the debt ceiling and further spending initiatives. That could take some steam out of Treasury yields and put the dollar on the defensive, especially if investors begin marking down expectations for additional fiscal expansion.

If nothing else, it would throw a wrench in the dollar’s upside. To me, that is enough to add more downside risk to the dollar.

The other pressure point is the AI trade. The dollar has benefited from the enormous amount of global capital chasing US technology assets, and the recent selloff has already shown how quickly cracks in that investment theme can spill into safe-haven FX (JPY & CHF). Greater regulatory scrutiny under a Democratic Congress could add another headache for a sector already wrestling with valuations and the cost of financing its infrastructure buildout.

But there is a considerable difference between political scrutiny and an investment cycle being brought to its knees. The Fed’s reaction function remains the more powerful driver of the dollar, and a change in congressional control doesn’t automatically alter the monetary-policy outlook.

That is why I would resist chasing election-related dollar weakness without confirmation from US rates. Political headlines can move currencies in minutes; changing the underlying interest-rate differential generally requires something more substantial.

Meanwhile, Brent’s retreat below $105 has provided some relief to inflation expectations, although the oil market remains sensitive to developments in Middle East diplomacy. For now, cheaper crude has eased some immediate inflation pressure, but it hasn’t eliminated the broader change in the Fed reaction function.

The Euro Has Its Own Political Baggage

EUR/USD has been trying to establish a foothold around 1.120, helped by a softer dollar and an ECB that still sounds reluctant to take its foot off the monetary brakes.

Recent central-bank commentary has reinforced expectations for at least another rate increase, with elevated energy prices leaving policymakers little room to entertain a genuinely dovish shift. That gives the euro some interest-rate support, particularly if the US election begins weighing on Treasury yields.

But the single currency isn’t exactly travelling light.

French sovereign spreads have remained stubbornly above 150 basis points despite the recent retreat in oil prices, suggesting the market is still demanding a hefty political and fiscal risk premium. That is hardly the sort of backdrop in which euro bulls can expect a free ride.

The euro may benefit from a weaker dollar, but until French spreads begin behaving themselves, I would be reluctant to treat EUR/USD as a clean one-way trade. The ECB can keep talking tough, but the bond market is reminding everyone that Europe’s problems haven’t disappeared simply because Washington is stealing the headlines.

The Aussie Gets the Hike but Loses the Argument

The Australian dollar had its own unpleasant surprise after the Reserve Bank of Australia delivered the expected rate hike to 4.85%, only to wrap it in a rather dovish policy message.

The 6–3 vote was less convincing than markets had anticipated, particularly with almost the entire 25-basis-point increase already priced. More importantly, the RBA removed its reference to potential further tightening for the first time since June and downgraded its economic outlook, with falling house prices weighing on household spending and unemployment risks moving higher.

For FX traders, it was the familiar case of getting the hike but losing the forward guidance.

Governor Michele Bullock made it clear that previous tightening still needs time to work through the economy. Another increase remains possible, but the bar has moved considerably higher, leaving the RBA looking increasingly comfortable sitting on its hands.

That isn’t necessarily bad news for the Aussie beyond the immediate selloff.

AUD still offers the strongest short-term carry across G10, even after adjusting for volatility, while markets are pricing only about a one-in-three chance of another hike at upcoming meetings and already discounting 13 basis points of easing by the end of 2027. With expectations having moved a long way toward the dovish side, the scope for another substantial policy disappointment looks more limited.

A recovery toward 0.710 in AUD/USD by year-end remains a reasonable bullish scenario, although the currency will need some cooperation from global risk appetite. The recent AI-related turbulence has hardly been helpful for high-beta FX, and attractive carry offers little comfort when equity investors are scrambling to reduce exposure.

Carry is a fine travelling companion until volatility starts collecting the rent.

For now, the dollar remains vulnerable to a political adjustment, the euro is carrying its own fiscal baggage, and the Aussie is trying to find its feet after a central bank that delivered the rate hike but took away the excitement.

The midterms may change Washington’s political arithmetic, but they are unlikely to rewrite the FX playbook on their own. The more durable currency move will still come from the Fed, relative interest rates and whether the AI investment cycle can keep attracting the capital that has helped underpin the dollar.

The blue wave may throw a wrench into the dollar’s upside, but until the Fed’s reaction function starts turning with it, I’d be careful about mistaking a political speed bump for a change in the road.
