(Adds U.S. stocks)

LONDON, Oct 26 (Reuters) - Stock markets cooled on Monday as euphoria about the prospect of further central bank policy easing faded, with investors warning against over-confidence ahead of another week of interest rate decisions.
Comments on Monday from a key economic adviser to Prime Minister Shinzo Abe, who said the Bank of Japan did not need to boost its monetary stimulus as early as this week, have tempered expectations that Friday's policy review will see new action.
The monthly Ifo survey of German business morale dipped in October but beat forecasts, suggesting Europe's largest economy remains resilient in the face of a slowdown in emerging markets and the emissions scandal at carmaker Volkswagen (DE:VOWG) VOWG_p.DE .
Corporate expectations over a half-year horizon hit a seven-month high, suggesting many firms believe they can cope with the economic headwinds.
"We have had a pretty good rally in risk assets since the beginning of October ... Clients have only really got two or three more weeks to do anything before year-end and they are not going to take big positions going into December," said Sean Darby, a strategist at Jefferies.
"On Japan, people also may have read too much into the possible crossover from the ECB."
Bets that Japan's already massive stimulus would be increased had risen after China cut interest rates last week and the European Central Bank indicated it may add to its asset purchase programme in December. The U.S. Federal Reserve, which also meets this week, is also increasingly seen delaying its first rate increase for nearly a decade until next year.
Global equities, which have rebounded 10 percent from the depths of September's sell-off, were broadly flat on Monday, with the pan-European FTSEurofirst 300 .FTEU3 index down 0.2 percent. MSCI's index of Asia-Pacific shares outside Japan edged up 0.2 percent.
U.S. shares were also set to open lower, with futures down around 0.1 percent. Valeant Pharmaceuticals (N:VRX) VRX.N sank nearly 14 percent in pre-market trading after the company said it would set up a panel to probe allegations about its associations with specialty pharmacy distributor Philador.
Poland's benchmark equity index .WIG20 reversed early falls and rose 0.3 percent after the main opposition party Law and Justice won weekend parliamentary elections. The party confirmed its plan to introduce a banking tax as of January 2016, which hit bank stocks like PKO BP (L:BP) PKO.WA and mBank MBK.WA .
There were some mixed updates from earnings season. French carmaker Peugeot PEUP.PA fell 2.1 percent after a trading update and Philips PHG.AS fell 0.7 percent after warning that the sale of its Lumileds division was in doubt.
The prospect of more central bank cash was seen supporting bond markets, with Italian and Spanish bond yields at nearly their lowest levels in half a year on expectations additional ECB stimulus will lift lower-rated euro zone bonds. German Bund yields hovered just above 0.50 percent.
Portuguese yields bucked the trend, rising after opposition Socialists pledged to topple the government in a no-confidence vote, with political instability seen as a potential setback in Lisbon's path to recovery.
Crude oil prices edged higher but remained range-bound on indications that global storage is nearing capacity.
Iron ore futures in China and Singapore ticked lower amid pressure from a weak steel market, though copper prices edged higher. (Editing by Catherine Evans and Nigel Stephenson)
