UK 10-year gilt yields hit 5.45% this morning — up another 7 bps. That's a serious headache for the Treasury.

Higher yields mean higher borrowing costs. Every basis point makes the fiscal math harder. The government has to fund spending, service existing debt, and now do it all at rates that keep climbing.

This is shaping up to be one of the toughest budget cycles in years. You can't just wish away bond market pressure. The market sets the price, and right now it's saying: "Show us the plan, or pay up."

Watch the gilt market closely. It's not just a number — it's the cost of everything the government wants to do.
