The British pound's trade-weighted index rose to its highest level since June 24 2016, the day after the Brexit referendum vote.

The Bank of England's sterling exchange rate index GBPTWI=BOEL measures the overall change in the trade-weighted exchange value of sterling, calculated by weighting together exchange rates adjusted for their trade relationships and is closely tracked by market participants.

It rose to 83.288 on Thursday, jumping nearly 4% in over a month to vault over the highs seen last October. The BoE releases the data with a day's lag.
