LONDON, Aug 23 (Reuters) - World stocks stabilised just above last week's one-month low on Monday as an encouraging euro zone business survey and positive corporate merger activity news helped ease concerns about a global economic slowdown.
Mining shares gained as financial markets bet Australia's inconclusive weekend elections would lead to a change of government which would spell the end to a plan to impose tax on major iron ore and coal mines.
A Markit survey showed the euro zone's economic recovery moderated slightly this month but companies are more optimistic about the coming months. HSBC <HSBA.L>'s plan to buy stakes in South Africa's Nedbank <NEDJ.J> in a potential $6.8 billion deal also brightened investor sentiment.
In Asia, a wave of mergers is boosting values as acquirers leverage on relatively lower valuations and cheap funding costs to buy companies. An estimated $58 billion worth of mergers involving Asian companies were playing out during the day.
Positive corporate news helped ease concerns that a renewed spike in U.S. unemployment may force the Federal Reserve to implement additional monetary easing.
"In terms of a positive trend we have some more M&A speculation but that doesn't seem to have lit the touch paper in terms of the market," Richard Hunter, head of UK Equities at Hargreaves Lansdown Stockbrokers said.
"It's a continuation of the August theme of light volumes and fragile sentiment." MSCI world equity index <.MIWD00000PUS> rose 0.1 percent after hitting a one-month low last week. The Thomson Reuters global stock index <.TRXFLDGLPU> was steady on the day.

]Old Mutual <OML.L> was up nearly five percent after HSBC <HSBA.L> said it would buy up to 70 percent of South Africa's Nedbank <NEDJ.J>, in which Old Mutual has a controlling stake.
Basic resources shares were the top gainers <.SXPP>.
Emerging stocks <.MSCIEF> were steady on the day.
U.S. crude oil <CLc1> fell 0.2 percent to $73.70 a barrel, near Friday's six-week low of $73.19. Prices have fallen more than 10 percent from an Aug 4 high of $82.97 as concerns about the global economy darkened the outlook for energy demand.

ELECTION RESULTS HIT AUSSIE
The Australian dollar briefly hit a one-month low of $0.8833 <AUD=D4> after neither of the major parties in Australia won an overall majority in Saturday's election to form a government, leaving the country facing its first hung parliament in 70 years. [
]The dollar <.DXY> was down around 0.1 percent against a basket of major currencies. The yen rose a quarter percent to 85.35 per dollar, which in turn weighed on Tokyo stocks <

"In the absence of a further sharp appreciation of the exchange rate towards 80 or a disorderly slide in the equity markets, we do not anticipate any easing of monetary policy until the scheduled policy meeting due on Sept 6-7, when we expect a further expansion of the BOJ's funds-supplying facility," Daiwa Capital Markets said in a note to clients.
