Why did cable head higher yesterday?

We're simply looking at the difference between two stimulus regimes.

With the BoE indicating that there would be a cap to stimulus, whilst the Fed earlier last week pretty much took a 'whatever it takes' stance, the longer term differential in narrative was created.

Whether that sustains is a different story, since context can change rapidly, but intraday, those comments let to higher UK yields which creates an implied appreciation in cable.
