Of course it was too good to be true.
But those who said such a mighty jump to the giddy highs of $1.23 and €1.12 (compared to $1.48 and €1.30 back in June), would just trigger a fresh round of selling and loss-cutting have been proved right this morning.
After an hour-long rally after a decent jobs report, sterling lost any trace of shine by mid-morning and was back in decline against both the dollar and the euro. After slumping to $1.2260, then surging to $1.2320, the pound was down 0.1 per cent below $1.23. Sterling was also down 0.2 per cent on the day compared to the euro at €1.1174.
The falling pound failed to provide any momentum to bluechip stocks either, as traders were left nervous after building giant Travis Perkins announced 600 job losses.
The FTSE 100 was off by 0.1 per cent in morning trading, back below the psychological barrier of 7,000 at 6,993. Travis Perkins was down 6.6 per cent, followed down by Reckitt Benckiser who shed 2.8 per cent after they missed earnings expectations for the third quarter.
