"The US dollar index was lifted by the US inflation figures, and the tariffs delay announcement helped with the positive move. The greenback has been held back by the US-China trade tensions, and we might see some more funds flow in to the dollar in light of the trade news," said David Madden at CMC Markets.Headline US inflation accelerated in July amid higher prices for energy and other goods and services, the Labor Department said. The US Labor Department said the consumer price index rose 1.8% year-on-year in July, following a 1.6% increase in June.

Turning back to beneficiaries from the easing in US-China trade tensions, Brent oil was quoted at USD60.84 a barrel at the London equities close Tuesday from USD58.36 late Monday."Oil was given a shot in the arm due to the tariff news, and dealers bought into the energy market in the belief that an easing of trade tensions should equate to a higher demand for oil, particularly in China, which is a major importer of the energy," said David Madden at CMC Markets.This caused BP to rise 1.4%, Royal Dutch Shell 'A' shares to end up 1.0% and 'B' shares up 1.6%.However, safe haven asset gold gave back gains on the news, quoted at USD1,502.50 an ounce at the London equities close Tuesday against USD1,508.22 at the close on Monday.

I think that the current pullback could be an opportunity for gold traders to add more into their position especially if price drops below USD1,500," said Aslam.Miners exposed to industrial commodities were among the top performers amid Tuesday's trade news.
