The US dollar that rallied on the slightly hawkish tilt in the Fed Chairwomen Janet Yellen's economic views on 15 July, strengthened further the next day as data releases from Switzerland, eurozone and the UK were largely on the negative side.

The USD index, the gauge that measure the greenback's strength versus the currencies of the six largest trading partners of the US, rose to a one-month high of 80.39, up 0.2% from Tuesday's close.

EUR/USD fell to a one-month low of 1.3529, down 0.3% on the day while GBP/USD dropped to 1.7113, down 0.17%. USD/CHF jumped 0.3% to a one-month high of 0.8963 and USD/JPY traded at a 7-day high of 101.78.

Eurozone May trade surplus was pretty much unchanged at €15.3bn (£12bn, $20.7bn)) while analysts were expecting a wider €16.3bn, data showed on Wednesday.

Swiss ZEW expectations index fell to 0.1 for July from 4.8 in June against the consensus of a rise to 5%.

UK claimant count change data for June was positive, coming in at a decline of 36,300 against market expectations of a moderate decrease of 27,000, but the growth of average earnings in the three months to May was less than expected from the year earlier.

The Fed Chair Janet Yellen had balanced her remarks in the biannual testimony from the Senate's banking committee on Tuesday; that she didn't want to be particularly dovish was taken as hawkish by the markets, or so showed the dollar rally afterwards.

The US producer price index data for June and details of foreign flows to Treasuries in May are due later today, and are likely to impact the greenback.

However, the market will mainly focus on Yellen, who is continuing her testifying in front of the US lawmakers, in addition to the Fed's Beige Book, due later in the day.

Weekly jobless data and Philadelphia Fed's manufacturing survey for June due on Thursday will be the next numbers from the US ahead of the July Reuters/Michigan confidence index and the June Conference Board leading index scheduled for Friday.
