UK PM Burnham says market turbulence is due to Tory record of raising debt; doesn't rule out tax increases

That sequence has historically mattered because gilt episodes of this kind resolve not on the rhetoric but on whether the fiscal rules are met through revenue raising or through spending restraint, since the former tends to be more durable for the deficit path while the latter is more often revisited. Refusing to rule out tax increases keeps the long end sensitive to any hint of the upcoming fiscal event's composition, and in past UK episodes the telling moments have been the Office for Budget Responsibility's scoring of the package and the Debt Management Office's subsequent remit rather than the initial political framing. Blame attribution to the prior government is routine in these transitions and carries little signal on its own. What carries signal is whether the commitment to the rules is framed as binding even if it requires tax rises, which on previous occasions has steadied the curve, versus language hinting at rule changes, which has not. The follow-ons are any commentary from the Chancellor, the timing of the next fiscal statement, and the gilt auction calendar in the interim.
