Asian and European stock markets rose again, today, as G20 policymakers meeting in Shanghai sought common ground on how to reboot a struggling global economy in the face of renewed financial and political risks. Another day of steadier oil and currency prices supported the brighter mood. So Japan's Nikkei 225 index added 0.3 percent; China's Shanghai Composite index gained 1 percent; Hong Kong's Hang Seng index spurted 2.5 percent; Singapore's Straits Times index climbed 1.8 percent; and South Korea's Kospi moved up 0.1 percent.The European markets logged better gains. The UK's FTSE-100 had gained 1.1 percent, France's CAC-40 had jumped 2.1 percent, and Germany's DAX had surged 2.2 percent in intra-day trade. Setting the tone for the Shanghai meeting of the Group of 20, China's central bank chief, Zhou Xiaochuan, said Beijing still had the room and tools to support the world's second largest economy. With the world economy facing its most serious crisis of confidence since the global financial turmoil of 2008-9, economists and officials have raised the prospect of governments pledging together to spend more to bolster growth. But German Finance Minister Wolfgang Schaeuble was quick to declare that the scope for monetary and fiscal policy was exhausted globally and called for more structural reform. The Italian central bank governor said markets should not expect concrete action from the meeting.
