TOKYO, Nov 5 (Reuters) - The U.S. dollar hit a two-month high against a basket of major currencies on Monday after job reports last week highlighted relatively solid U.S. economic fundamentals.
The dollar stood near a four-month high against the yen and the euro also hit a five-week low, both tackling major chart points, though uncertainty over Tuesday's U.S. elections hindered decisive breaks there for now.
The dollar index, a measure of the dollar's value against six major currencies, rose to as high as 80.629, its highest level since Sept. 7 before giving up gains to stand virtually flat at 80.558.
U.S. employers stepped up hiring in October to 171,000, beating even the most optimistic forecast. The jobless rate rose a tenth of a point to 7.9 percent but that was because more people were looking for jobs.
Against the yen, the dollar hovered at 80.45 yen, easing slightly on profit-taking from a four-month high of 80.68 yen hit on Friday after the payroll data.
The dollar has a major resistance at 80.65, a 50 percent retracement of its slow but steady decline from March to September.
"After the dollar/yen has tested a key Fibonacci level, it needs a bit of consolidation in the very near-term," said Teppei Ino, currency analyst at the Bank of Tokyo-Mitsubishi UFJ.
"But the dollar looks likely to maintain its uptrend. The dollar charts look bullish and better economic fundamentals in the U.S. compared to Japan's also favour the dollar," Ino said.
While the U.S. jobless rate still 3 percentage points above its pre-recession levels, recent uptick in U.S. jobs and consumption data contrasted with deteriorating economic picture in Japan and Europe.
Japan's industrial production, a key leading indicator of the manufacturing-driven economy, has been falling sharply, helping to prompt the Bank of Japan to ease its policy for two months in a row - something it had not done for nearly a decade.
In Europe, data on Friday showed car sales slumped to 1993 lows, underscoring the impact of the debt crisis on consumption.
The euro fetched $1.2829, flat from late U.S. levels, after having fallen to as low as $1.2816 in thin early Monday trade.
If the euro on Monday closes below its 200-day moving average, at $1.28297, that would be the first time since September, and before the U.S. Federal Reserve started QE3. Closing at that level might signal a departure from its $1.28-$1.32 trading range since then.
The euro is coming under pressure from uncertainty on Spain and Greece, but its immediate support is at the Oct. 1 trough of $1.28035 for now.
More immediate attention is on the U.S. presidential and congressional elections as the American economy, despite its recent firmness, faces a real threat of a renewed recession next year depending on how Washington deals with the fiscal cliff -- about $600 billion in government spending cuts and higher taxes that will be enacted next year if the congress can't agree new arrangements.
"Investors hate uncertainty, so there will be a sigh of relief when the election is over. Provided there is a clear election result and no change in the divided Congress, then traders and investors will see it as 'business as usual'," said Craig James, chief economist at CommSec.
If the party of the winning presidential candidate also gains control over Congress, "then investors would be expected to react positively," James said.
With the Republicans seen retaining control of the House, the re-election of President Barack Obama would be seen as raising the risk of policy paralysis, which is likely to mean no fresh deal for the fiscal cliff and a sharp economic downturn early next year.
On the other hand, if the Republicans win both the presidency and the Senate, that would be seen as positive for risk sentiment, though market players see limited chance of that happening.
Elsewhere, the Aussie rose 0.3 percent to $1.0366, after data showing a pick-up in retail sales, though the data left the market still guessing whether the Reserve Bank of Australia will cut rates on Tuesday.
