If the UK and the EU fail to reach a Brexit agreement, there will be a great deal of focus on the value of pound.
Back in June 2016, when the UK voted to leave the European Union, sterling plunged against the dollar and it has been volatile since though it has never managed to surpass $1.50 against the dollar.
Over the past week, the pound has been buffeted by the changing language emerging from the Brexit negotiations and is currently trading around $1.32.
So what does Foreign Secretary Dominic Raab expect to happen to the pound?
"There has already been currency fluctuations. Of course there's a flip side temporarily for that, it is a boost to exporters but obviously it has a challenge domestically," he told The Andrew Marr Show.
When currency markets in Asia open this evening, we'll get our first indication of the scale of those challenges.
The pound "seems to like this reshuffle," says Neil Wilson of Markets.com.
He notes that the pound fell against the dollar after Sajid Javid resigned as chancellor. But it swiftly rebounded through 1.30 toward 1.30240 when Rishi Sunak was announced as his replacement.
Gilt yields also moved higher, with the market betting on "more spending, less austerity and more growth," under the new chancellor.
Mr Wilson describes the move as a "blatant power grab by Boris and Cummings over the Treasury".
"Boris Johnson is taking the Kirstie Allsopp approach to how to make Number 10 and Number 11 work for him: that is, just knock through.
"The fiscal floodgates are about to open – whatever brake the Treasury might have had on Number 10 has been cut entirely with this move."
The pound has risen 0.35% against the dollar to $1.3067 after the Bank of England's Monetary Policy Committee voted to hold the interest rate.
Sterling also gained against the euro, up 0.21% at €1.1849.
The MPC made clear, however, that it may act if the UK economy fails to gain momentum.
"With Mark Carney seemingly having deferred this policy decision to his successor, Andrew Bailey will need to land on his feet running," says Principal Global Investors' market strategist, Seema Shah.
"Unless economic activity data improves measurably over the coming months, reflecting proof of the so-called 'Boris bounce', and interest rate cut is likely to remain on the agenda for 2020.".
