Wall Street jumped and the US dollar fell as the US Federal Reserve played down its forecast for interest rate increases.
The minutes from the US central bank's latest policy meeting eased concerns about the timing of rate rises.
In Janet Yellen's first press conference as chair late last month it was implied that interest rates might rise faster than the bank previously predicted.
Today the Fed said those comments overstated the outlook.
"Several participants noted that the increase in the median projection overstated the shift in the projections," the Fed statement read.
Wall Street liked the message and rallied.
"These minutes are calming for the markets," said Jeffrey Kleintop, chief market strategist at LPL Financial.
"A slower pace of interest rates seems more likely here. The six months language Yellen said does not appear here."
