This feels a little odd as some of these things feel like they should be part of the budget announcement itself. Markets are already of course taking to it and reacting accordingly with UK gilt yields tumbling lower while the pound spiked higher for a brief moment before settling a little bit.
10-year yields in the UK are down from 4.50% to 4.46% while GBP/USD pushed up from around 1.3155 earlier to 1.3185 currently with the high earlier touching 1.3200.
The big round numbers are what we're looking for and they are a positive, especially the fiscal headroom indicated in the headline. So, no need for Reeves I guess? Seems like we could just call it a day unless she messes up the delivery.
