The big picture
On Polymarket, the market's price on Democrats winning the Iowa Senate in 2026 fell 21 points in a single day, nearly twenty times its normal daily move, and now trades at 38% chance of happening.

Three of the five biggest movers sit in the Americas: Iowa, a Harris presidential-run announcement, and Brazilian election dynamics, clustering a political reordering in the region. The political shifts are unrelated to the economic backdrop, where household wallet pressure continues unchanged. Mortgages remain at 6.95%, gas at the pump at $4.32, and consumer sentiment depressed at 55 despite a tight labor market with jobless claims at 196k.

6.95%
up from 6.67% a month ago, near its highest in the past year.

196k
down from 212k a month ago, near its lowest in the past year.

30-year Treasury rate Warning
5.35%
about the same as a month ago, near its highest in the past year.
30-year Treasury rate is 5.35%, about the same as a month ago, and near its highest in the past year. If the recent trend holds, tomorrow it would be near 5.39% (a trend estimate, not a forecast).

The 30-year Treasury rate at 5.35% is in the fiscal crisis zone where borrowing costs for governments spike, making it harder to finance deficits and raising mortgage rates as a side effect.
