Why the PM could finally drop the triple lock pension pledge

A formal announcement to modify or suspend the triple lock would likely put downward pressure on gilt yields in the near term, as markets would price in reduced future government spending commitments, though sterling could face headwinds if the move is perceived as politically costly or signals broader fiscal retrenchment.

Continued ambiguity around the triple lock's future would plausibly leave gilt and sterling markets to focus on other fiscal signals, with pension-related volatility remaining muted unless inflation or wage data force the government's hand into a more explicit policy stance.

A public row between the government and pensioner groups or backbench MPs over attempts to weaken the pledge could erode confidence in fiscal credibility, potentially widening gilt spreads and creating near-term sterling weakness as markets reassess political risk around spending commitments.
