LONDON, June 29 (Reuters) – Sterling edged down to its lowest in over a week against the dollar on Tuesday, with the British currency on track for its worst month since September.
A broad strengthening in the dollar in recent weeks after a surprise hawkish shift by the U.S. Federal Reserve has brought some volatility back to currency markets, while also toppling sterling from levels near 3-year highs.
The fall in the currency has caused a shakeout in speculative bets, although CFTC data still shows the market maintaining a net long position on the pound.
