One analyst in early June was predicting quite a sharp change in the euro sterling exchange rate.
James Smith, an economist with ING was quoted as saying that markets are bracing themselves for no extension for the UK leaving the transition phase and hence the EU at the end of the year.
Smith believes that sterling could fall to 91 cents by the end of June.
(Thankfully it hasn't gone that far - sitting now at around €1.09 - although recent reports of walking away from talks could see sterling drop further by end of month).
Most other observers and currency analysts do not expect such a dramatic currency scenario. However things are looking sticky enough with the talks between the UK and the EU at this point in time.
