BoE's Taylor says right policy response is therefore vigilant but disciplined and monetary policy should not react mechanically to movements in energy prices if those movements remain primarily relative-price shocks

On past occasions when supply-side energy shocks have hit, the debate inside rate-setting committees has split along exactly this line: those treating the shock as a level shift to be accommodated versus those focused on wage and expectations pass-through, and it is the persistence of the shock and the behaviour of core and services inflation that has historically decided which camp prevails. The phrase vigilant but disciplined signals conditional restraint, keeping the door open without pre-committing, and in prior episodes such language has tended to leave rate pricing anchored unless accompanied by evidence of broadening domestic price pressure. Taylor sits on the more dovish end of the MPC spectrum in recent form, so the remarks carry less surprise value than they would from the committee's centre; the tell is whether the median members adopt the same relative-price framing, since that is what shifts the path rather than any single voice. Worth observing in follow-through is how the comments sit against the energy curve itself: a sustained move has historically eroded the relative-price defence faster than a spike that mean-reverts, and the next inflation prints become the arbiter.
