Stock traders see elections as a headline event. Bond traders see them as a fiscal one. Moving closer to the US midterms on 3 November, investors may be looking past who wins and asking what the result could mean for spending, deficits and policy expectations - those are the things that tend to show up in Treasury yields before they reach share prices.
The bond market is already moving. The 10-year Treasury yield pushed above 5% in mid-September, its first move past that level since 2023,1 and touched 5.34% in early October, its highest in 24 years,2 as rising oil prices and inflation worries sparked a sell-off. The administration has been looking to bring borrowing costs down ahead of the vote, and the Treasury has stepped up its buybacks of longer-term debt, doubling the maximum size of its operations in the 10- to 30-year sector from $2 billion to at least $4 billion.3 Yields have stayed elevated regardless, with the 10-year at 5.24% on 9 October,4 and markets are pricing a meaningful chance of a further Federal Reserve (Fed) rate increase after September’s hike.5
That makes rates the first place to look for any election-related repricing.
A divided Congress could limit new spending. A unified one might find it easier to extend tax cuts or add fiscal support. Either way, the bond market’s question is the same: how much debt needs to be absorbed and at what price?
That’s why the volume of new government debt being sold to investors is a real risk. If there is a lot of debt on offer and not enough buyers, the government has to offer higher yields to attract them. Whatever the political story, yields can jump quickly.6
History hints at some possible relief. Over the years, 10-year yields have tended to rise in the first half of a midterm year and ease in the second.7 But that’s a pattern, not a promise. The 10-year rose sharply in the third quarter,8 and this year’s inflation and oil dynamics could override it.
Here’s how a shift in yields could ripple through the market:
Here’s your checklist for the weeks ahead:
Election outcomes are uncertain, and no single result is guaranteed to move markets in a particular direction. What's clearer is how the chain works: fiscal expectations feed into yields, yields into the dollar, and from there into banks, growth shares, gold and housing-linked stocks.
If the midterms do move markets, the bond market may be the first to say so. Stay tuned, this one could get interesting!
