TOKYO, Oct 12 (Reuters) - The dollar inched up in early Monday trade as riskier currencies slipped after negotiation on a U.S. stimulus package ran into resistance and as the yuan dropped after China's central bank took a measure seen as aimed at curbing its strength.
The euro slipped 0.1% to $1.1817 while the Australian dollar shed 0.3% to $0.7222. The yen was little changed at 105.52 to the dollar.
The U.S. dollar index edged up to 93.108, bouncing back from Friday's near-three-week low of 92.997. The index saw its biggest loss in six weeks on Friday on hopes that a deal for new U.S. stimulus would be reached.
President Donald Trump on Friday offered a $1.8 trillion coronavirus relief package in talks with House Speaker Nancy Pelosi - moving closer to Pelosi's $2.2 trillion proposal.
But Trump's offer drew criticism from several Senate Republicans, many of whom are uneasy about the nation's growing debt and concerned a deal would cost Republicans support in the upcoming presidential election, denting the risk-on mood.
Still, with Nov. 3 election only weeks away, investors bet that Democrat Joe Biden is more likely to win the U.S. presidency and offer a larger economic package.
"Over the past few days, the markets seem to assume Biden will win the election. Trump seems desperate to get a deal but his comments are getting treated like a noise," said Yusuke Okada, manager of forex at Mitsubishi Trust Bank.
"But I do think we could see a return of political uncertainties by the election. Markets seem to have priced in only the good news," he added.
FORWARD THINKING
The offshore Chinese yuan dropped after the People's Bank of China (PBOC) said it will lower the reserve requirement ratio for financial institutions when conducting some foreign exchange forwards trading.
Analysts said the measure could keep the yuan's strength in check by encouraging the use of forwards.
"The authorities have not stood in the way of yuan strength, but this move could be seen as a sign that they want to slow the pace of appreciation," wrote Khoon Goh, head of Asia Research at ANZ in Singapore.
"Our interpretation is that removing the reserve requirement is intended to encourage firms to hedge in order to manage currency risk. It also enhances the foreign exchange market structure by making it easier for foreign investors to hedge their onshore portfolio investments."
