* U.S. jobs report likely to confirm sub-par trend
* Bank of Japan poised to ease as economy takes a hit
* Spain stuck in recession, underscoring euro zone woes
LONDON, Oct 28 (Reuters) - The last employment report before the U.S. presidential election is likely to have something for everyone - for those bullish and bearish on the economy and for Barack Obama and Mitt Romney.
Non-farm payrolls in October are forecast to have risen 124,000, barely more than September's 114,000 gain, according to 78 economists polled by Reuters. The unemployment rate probably edged back up to 7.9 percent after falling to 7.8 percent from 8.1 percent last month. The figures are due on Friday.
On the face of it, that would reinforce the charge levelled by Romney, a Republican, that the policies of his Democratic opponent are to blame for the slowest post-recession recovery since the war.
The proportion of America's working-age population that is employed has fallen to 58.7 percent from 60.6 percent when the Democrat took office in January 2009.
But Obama can counter that nearly 800,000 more Americans are in work today than when he became president and that five million jobs have been created since the December 2009 trough, according to the Bureau for Labor Statistics.
In many respects, the job statistics are likely to paint the same blurred picture as Friday's report showing the economy expanded at a 2.0 percent rate in the third quarter: things are improving, but at a frustratingly slow pace.
``For this reason the labour market is currently neither weak enough to do serious damage to Obama's re-election chances nor strong enough to give him a boost,'' said Bernd Weidensteiner, an economist with Commerzbank in Frankfurt.
Opinion polls show the Nov. 6 election is too close to call.
Douglas Roberts, an economist with Standard Life Investments in Edinburgh, said a weaker-than-expected jobs report would not make him too concerned about the U.S. economy. Housing in particular was rebounding smartly, albeit from a low base.
But any softness would underline the urgency of eliminating policy uncertainty that is causing businessmen to sit on their hands, not least the prospect of tax increases and spending cuts that will kick in next year in the absence of a long-term agreement to cut America's budget deficit.
``Investment and recruitment are being held back until companies have a much better idea of the economic environment they're going to be looking at after the election and the 'fiscal cliff' negotiations are through,'' Roberts said. ``So I don't think the payroll numbers will tell you an awful lot.''
The other data highlight of the week is the monthly survey by the Institute for Supply Management, which is closely watched in Asia as a pointer to export and production trends.
Economists polled by Reuters expect the ISM index to be unchanged at 51.5.
David Lubin at Citigroup said there was a ``decent relationship'' between the ISM survey and the export orders component of China's official purchasing managers' index, which is expected to creep higher. Both reports are due on Thursday.
Signs of stabilisation in recent Chinese data, including credit growth and rising imports, were a cause for qualified optimism about the prospects in some other Asian economies, Lubin said in a report.
``But there is no systematic evidence that the revival in Chinese import demand is generating positive spillovers in a large number of countries,'' he added.
BANK OF JAPAN TO STEP UP
That is definitely the case in Japan, whose firms have scaled back sales, output and investment in China after the recent flare-up of a territorial dispute over islets in the East China sea led to violent protests across China and a partial boycott of Japanese goods.
With the economy also on the ropes because of the strong yen, the Bank of Japan is widely expected to deliver more monetary stimulus when it meets on Tuesday to prevent the world's third-largest economy from relapsing into recession
Recession already has a firm grip on swathes of the euro zone, hit by a debt and banking crisis that is being exacerbated by austerity measures to reduce yawning budget deficits.
Data on Wednesday will probably show that the unemployment rate for the 17 countries using the single currency rose to a record high of 11.5 percent in September from 11.4 percent in August.
In Spain, which on Friday reported a jobless rate of 25 percent, the economy is likely to have shrunk by 0.4 percent in the third quarter, just as it did in the second quarter. Madrid releases the report on Tuesday.
