The euro has dropped below parity against the dollar the first time in almost two decades after news that US inflation reached 9.1% in June.
The figures will place further pressure on the Federal Reserve to hike interest rates by 75 basis points later this month, as raising interest rates is one of the tools used by central banks to fight inflation.
The 9.1% surge – the highest level in 40 years – is compared to the same month last year, and is up from the 8.6% jump seen in May.
On a monthly basis, prices rose 1.3% from May to June, after rising 1% from April to May.
Richard Carter, head of fixed interest research at Quilter Cheviot, said: “This disappointment means that a 0.75% hike from the Federal Reserve at their next meeting is an absolute certainty and there may even be pressure from some quarters for them to do more.
“Central banks are clearly struggling to get a handle on inflation and if this number continues to grow or hover around this level then more will be required to drive it down, regardless of the economic consequences this may have.
“Markets are likely to remain volatile on the back of this although the fall in the oil price in recent days does offer some hope that inflation pressures will begin to ease later in the year.
