UK public sector net debt tops £3 trillion for first time

The milestone matters less as a round number than as a signal of how debt interest costs are now competing with discretionary spending, which narrows the government's room to absorb further fiscal shocks. The pressure lands squarely on the Treasury, and by extension on gilt issuance and the domestic policy debate over spending restraint versus investment. Whether borrowing continues to overshoot expectations, and how debt servicing costs evolve against the broader rate environment, is the open question worth tracking.
