Asian markets, yuan rise as US-China tensions ease further

Asia equities extended a global rally on Tuesday, with the US decision to no longer designate China a currency manipulator a further sign of easing tensions between the economic titans.

The Treasury announcement came days before the two sides are due to sign off on the first part of a wider trade agreement that has helped fan a rally in world markets.

It also led to a sell-off in safe-haven assets with the yen at a seven-month low and gold down almost one per cent, while oil was also struggling with the US-Iran flare-up seemingly in the rear window for investors.

Asia was given a firm lead from Wall Street, where all three main indexes ended higher with the Nasdaq and S&P 500 hitting fresh records on reports the US was about to remove the manipulator label from China.

Donald Trump accused Beijing in August of weakening its yuan currency "to steal our business and factories", re-stating a long-standing grievance. 

But soon after the end of trade on Monday, the Treasury said in its semi-annual report to Congress that the unit had strengthened and Beijing was no longer keeping it artificially weak.

The yuan jumped more than one per cent at one point Tuesday before easing slightly. The currency is up more than four per cent from an 11-year low touched in September. 

"The yuan is the purest and best barometer to gauge the market's view on US-China trade tension," said AxiTrader's Stephen Innes. "With the yuan strengthening ahead of the 'phase one' deal signing, it's indicating the potential for further improvement in trade relations."

The US reversal of China's status as a manipulator "is a most precise and definitive de-escalation of trade tension to date and provides a less congested road as we pivot to phase two of the broader trade agreement", he added.

Tokyo was among the biggest gainers, rising 0.7 per cent by the break as the dollar advanced against the yen owing to a rush out of safety giving a boost to Japan's exporters.

Hong Kong and Shanghai both gained 0.2 per cent, while Singapore put on 0.3 per cent and Seoul 0.7 per cent.

Sydney was up 0.6 per cent, Wellington and Taipei both gained 0.5 per cent and Jakarta put on 0.2 per cent.

Improving confidence also hit gold, which is a popular go-to asset in times of turmoil. The yellow metal last week broke $1,600 for the first time in seven years on the Iran crisis but the lowering of expectations for a conflict with the US has seen it tumble more than four per cent from its recent high.

The improving China-US outlook saw it drop by 0.9 per cent on Tuesday.

As well as Wednesday's signing, investors are also looking forward to corporate earnings season, which kicks off in earnest this week with the release of reports from top banks including Citibank, Goldman Sachs, and JP Morgan.

"Our expectation is a solid earnings season nothing extraordinary but nothing really terrible," Kristina Hooper, chief global market strategist at Invesco told Bloomberg TV. 

"The environment is so accommodative that it really is supportive of risk assets, including equities, even if we have a lacklustre earnings season."
