World stocks slipped on Tuesday, despite emerging market gains, while the euro recovered on expectations of higher interest rates.
Portugal's debt remained under pressure, with yields on its 10-year bonds near record levels above 8 percent, complicating the country's attempts to avoid a European Union bailout.
World stocks as measured by MSCI were essentially flat to slightly lower, but the emerging market component gained more than a quarter of a percent.

"Some investors concluded now it's an opportunity to pick up some shares," said Shane Oliver, head of investment strategy at AMP Capital Investors in Sydney. "The broad trend is up and dips are being bought."
Europe was lower, however, with the FTSEurofirst 300 down 0.4 percent. Volume has begun to fall on European bourses in line with 2011 lows on Wall Street.

Investors have generally focused on the improving world economy, but the crises and worries about inflation may be taking some toll.

The single currency had dipped on Monday after hawkish U.S. policymaker comments lifted the dollar, but it failed to break below $1.40 before it moved back up as Trichet said inflation was "durably" above the ECB's target.
Investors continued to focus on the prospect of higher rates and continued to shrug off the euro zone debt crisis, with concerns rising about Portugal's ability to finance itself as the country prepared for a snap election.
The euro was up 0.4 percent at $1.4135.
German government bonds opened slightly higher but Portuguese debt remained under pressure.
