Hopes of government-sponsored bailouts rescued global markets once again this week, sending equities higher worldwide on Friday.

In Asia, the Shanghai Stock Exchange Composite Index rose 1.19 percent to close at a one-month high. European stocks also fared well, as the Germany DAX index rose 1.18 percent. In the U.S., the sentiment was more muted, with the benchmark S&P 500 closing with a gain of 0.12 percent.

The China Securities Journal quoted a central-bank official as saying that the bank will inject more liquidity into the Chinese financial system through open-market operations and the reduction of bank reserve requirement ratios, reported China Daily, a media outlet affiliated with the country's government.

Even the Bank of Japan looks poised to take more monetary stimulus actions in the near future.

U.S. officials have not hinted at any further stimulus measures. However, if the country's labor market begins to deteriorate again -- as the unemployment-claims data over the past two weeks appeared to suggest -- stimulus talks will likely heat up again.

Over in Europe, the boost from the European Central Bank's latest large-scale liquidity injections -- the long-term refinancing operations conducted in February and December for more than €1 trillion -- seems to be wearing off already as yields on Spain's 10-year yields moved above 6 percent this week.

In any market analysis of the stress in Europe and employment issues in the U.S., every conversation comes back to when will central bankers act, said Peter Boockvar, equity strategist at Miller Tabak, an institutional trading firm.
