Asia

China’s yuan fell to an 11-year low against the dollar on Monday and stocks dropped as the Sino-US trade war sharply escalated, threatening to inflict more damage on the world’s largest economies.

Share prices also tumbled in Hong Kong as trade tensions mounted and after a weekend flare-up in violence during anti-government protests.

The onshore yuan slumped as much as 0.7 per cent in the first few minutes of trading to 7.15 per dollar, its weakest since February 2008 and its second biggest one-day drop of the month. The offshore yuan fell to a record low of 7.1850.

But the currency later pared losses after US President Donald Trump said on Monday he believed Beijing wanted to make a trade deal. Trump said China had contacted US trade officials overnight to say it wanted to return to the negotiating table.

The Chinese authorities have allowed the tightly-managed yuan to slide some 3.6 per cent so far this month as trade tensions between Beijing and Washington have worsened, sparking fears of a global currency war. It was trading around 7.1456 by 0745 GMT.

The benchmark CSI300 Index ended down 1.4 per cent while the Shanghai Composite Index fell about 1.2 per cent, with Trump’s comments hitting trading screens just before the close. Chinese 10-year Treasury futures rallied 0.3 per cent in early trade on Monday but eased later in the day.

In Hong Kong, the Hang Seng Index dropped more than 3% in morning trade as investor confidence continued to weaken amid the darkening trade outlook and the latest anti-government protests. Protests on Sunday saw some of the fiercest clashes yet between police and demonstrators.

The Hang Seng ended down 1.9 per cent.

The pan-European STOXX 600 index ended flat, clawing back ground after a Friday sell-off ignited by yet another tit-for-tat round of tariffs between the world’s two largest economies.

Trading volumes were thinned out by a UK holiday.

European equity markets were almost certain to follow their Asian counterparts into deep losses but recovered after US President Donald Trump said Beijing had contacted Washington to say it wanted to return to the negotiating table.

The change in tone came after China said it was willing to resolve the trade dispute with US through “calm” negotiation.

Trade-sensitive auto stocks led gains on the benchmark, having fallen 2 per cent in the previous session after China announced fresh tariffs on certain US goods.

On one hand it would inflict more pain on China and increase willingness to make a deal, though Trump will also be in need of a deal ahead of US elections, Spakman added.

In the meantime, sentiment remains jittery. Munich-based Ifo institute said its business climate index fell to the lowest level since November 2012, a further sign of the expected damage to the Garman economy, Europe’s largest, from the US-China trade conflict.

In corporate news, German real estate stocks came under pressure after a report that Berlin’s city government plans to cap rents. Shares in Deutsche Wohnen slid nearly 3 per cent.

European stocks have swung wildly in August over worries that the US-China trade war will eventually tip the global economy into recession, setting the STOXX 600 on course to end August lower.

Italian markets outperformed, with Milan's FTSE MIB closing 1 per cent higher as the opposition Democratic Party and the anti-establishment 5-Star Movement moved closer to a deal on forming a coalition government.

North America

Following the G7 summit of world leaders in Biarritz, France, Trump said on Monday he believed China was sincere about the desire to reach a deal, citing what he described as increasing economic pressure on Beijing and job losses there.

Shares of tariff-sensitive companies rose in response. Apple's 1.90 per cent gain provided the biggest boost to each of the major indexes.

Chipmakers, which are heavily reliant upon China for revenue, also rose. The Philadelphia Semiconductor index added 0.86 per cent after slumping more than 4 per cent on Friday.

Still, market participants said the rebound paled in comparison to last week's decline, and they expected recent volatility to continue.

The Dow Jones Industrial Average rose 269.93 points, or 1.05 per cent, to 25,898.83; the S&P 500 gained 31.27 points, or 1.10 per cent, to 2,878.38; and the Nasdaq Composite added 101.97 points, or 1.32 per cent, to 7,853.74.

Commerce Department data showed new orders for key US-made capital goods rose modestly in July while shipments fell by the most in nearly three years. The data could provide the Federal Reserve with more fuel to cut interest rates again when policymakers meet next month.

The S&P 500 is off more than 5 per cent from the record high hit in late July after suffering its longest run of weekly declines since May.

Even with Monday's broad gains, with each of the major S&P 500 sectors rising, Wall Street's fear gauge, the CBOE Volatility index, hit its highest level in more than a week earlier in the session.

Among other stocks, Celgene rose 3.20 per cent after Amgen said it would buy the company's psoriasis drug Otezla, clearing the way for Bristol-Myers Squibb to go ahead with its $US74 billion ($109 billion) deal for Celgene. Shares of Bristol-Myers rose 3.28 per cent
