SHANGHAI, Nov 13 (Reuters) - China's yuan fell to a one-week low against the dollar on Wednesday after U.S. President Donald Trump said he would raise tariffs on Chinese goods if the two countries fail to reach a trade deal. While Trump on Tuesday dangled the prospect of completing an initial trade agreement "soon," he offered no new details on negotiations, rattling investors who had been encouraged by signs of progress last month. "We're close," Trump said in a speech. "A significant phase one trade deal with China could happen. Could happen soon. But we will only accept a deal if it's good for the United States and our workers and our great companies." If a 'phase one' trade agreement fails, any tariff hikes would likely spark a re-escalation of China-U.S. tensions and could send the onshore and offshore yuan back to the 7.1 level quickly, said Ken Cheung, chief Asian FX strategist at Mizuho Bank in Hong Kong. "Investors should be alert to the event risk of a Xi-Trump meeting and should not take the phase one deal for granted." Twists and turns in the protracted trade dispute have been the key factor influencing the yuan's moves for over a year, with escalating U.S. tariffs putting further pressures on China's slowing economy. Onshore spot yuan fell to a low of 7.0270 per dollar at one point in morning trade, the weakest level since Nov. 5. At midday, it was changing hands at 7.0212, 139 pips or 0.2% weaker than the previous late session close. Prior to the market opening on Wednesday, the People's Bank of China (PBOC) set the midpoint rate at 7.0026 per dollar, 38 pips or 0.05% weaker than the previous fix of 6.9988. Wang Tao, an economist at UBS in Hong Kong, said the yuan should face continued downward pressure but should stay largely stable next year. "In our base case, additional tariff hikes in December and a further drop in China's external demand will likely put persistent depreciation pressure on the CNY," Wang said in a note on Wednesday. "In addition to the likely commitment associated with the 'phase one' trade deal, the government may be concerned about a sharp depreciation hurting domestic confidence and triggering capital outflows." The global dollar index rose to 98.336 at midday from the previous close of 98.309. The offshore yuan was trading at 7.0234 per dollar as of midday.
