European stock index futures rose 1 percent and the euro held near a 1-month high on Monday after France and Germany said over the weekend they were making good progress on a plan to resolve the euro zone's debt crisis and recapitalize its banks.
Asian share markets also rose, helped by positive earnings and better-than-expected retail sales data from the United States that boosted hopes that corporate results are holding up inspite of a gloomy global outlook.
But a commodities rally ran out of steam, highlighting concerns across riskier asset classes that there is still much work to do to avoid a meltdown in Europe's financial system.
It is too early to declare that sentiment has completely shifted, said Peter Esho, chief market analyst at City Index in Sydney. The market is still fragile but there is a good case for arguing equities are cheap.
G20 finance ministers and central bankers said at a meeting in Paris that they expected euro zone leaders to decisively address the current challenges through a comprehensive plan at a European Union summit on October 23.
French Finance Minister Francois Baroin, who chaired the meeting, said Berlin and Paris, the leading euro zone powers, were well on the way to agreeing on a plan to reduce Greece's debt, stop contagion and protect Europe's banks.
The market is growing more expectant of more aggressive measures from Europe aimed at solving its debt crisis, said Kim Young-june, a market analyst at SK Securities.
Some market players are talking of a binary moment for the euro zone in which the leaders' summit either comes up with the goods to assuage concerns about the debt crisis or disappoints markets again.
The former might well be taken as a reason for a sustained rally in riskier assets such as equities and commodities. The latter would almost certainly spark a sell-off.
For now, investors are looking at reasons to be hopeful.
Euro STOXX 50 index futures rose 1.1 percent. Futures for Germany's DAX and France's CAC-40 also rose around 1 percent, and financial spreadbetters called the FTSE 100 <.FTSE> to make similar gains. <.EU> <.L>
In Asia, Japan's Nikkei share average <.N225> and MSCI's broadest index of Asia Pacific shares outside Japan <.MIAPJ0000PUS> both rose 1.5 percent. <.T>
The materials sector <.MIAPJMT00PUS> in the MSCI index gained more than 2 percent, boosted by a 2.4 jump in shares of mining giant Rio Tinto
U.S. stocks rose on Friday, with the S&P 500 <.SPX> up 1.7 percent, on optimism about Europe and after strong earnings from Google Inc.
The CBOE Volatility Index <.VIX>, also known as the Vix or Wall Street's fear gauge, fell 8 percent, an indicator that risk appetite was returning.
S&P futures advanced 0.4 percent in Asia on Monday.
The euro held firm after posting its biggest weekly gain in 9 months last week. The single currency traded around $1.3845, down 0.1 percent on the day but well off a 9-month trough of $1.3144 set on October 4.
After the developments at the latest summit, we can assume that at long last concrete measures to solve the crisis will be implemented next weekend, said Sumino Kamei, senior currency analyst, Bank of Tokyo-Mitsubishi UFJ.
Such measures are broadly assumed to include a plan to make Greece's debts more manageable through bigger haircuts than have already been agreed for private bondholders and bolstering the firepower of the euro zone's rescue fund.
Much of the euro's gains, however, have been from short-covering -- when market players buy to realize a gain on an earlier bet against the currency -- and if EU leaders fall short of the grand plan that markets are now expecting the euro will quickly come under renewed pressure, traders warned.
Hopes of progress in Europe have also brought relief to Asian credit markets, with spreads on the iTraxx Asia ex-Japan investment grade index tightening further on Monday. The index has now tightened by a dramatic 26 basis points over the past week.
Growing risk appetite also reduced demand for safe-haven government bonds, with the benchmark Japanese government bond 10-year yield rising 0.5 basis point to 1.020 percent.
U.S. Treasury 10-year yields rose around 1.5 basis points to about 2.265 percent, after climbing 19 basis points last week, while the dollar firmed 0.1 percent against a basket of currencies <.DXY>.
Commodities markets were boosted last week by data suggesting that China, a key source of resources demand, is containing inflation and so more likely to avoid an economic hard landing.
Copper eased 0.4 percent to $7,514 a tonne on Monday, after rising more than 3 percent in the previous session, and oil was steady, with Brent crude flat at $112.29 a barrel and U.S. crude up 0.3 percent at $87.09.
Gold, which in recent months has switched from a negative to a positive correlation with riskier assets such as industrial commodities and stocks as safe haven investors turned instead to the dollar, was little changed around $1,679 an ounce, after its biggest weekly gain since early September last week.
