Greece's radical new leaders flew into Rome Tuesday seeking to build support for new proposals aimed at ending a stand-off with the country's creditors and its European Union partners.
In an interview with the Financial Times, Greek Finance Minister Yanis Varoufakis said the leftist-dominated government in Athens would be making proposals for "a menu of debt swaps" that would avoid the need for any of the country's mountain of foreign debt to be written off.
"Greece’s problems are far from over but as far as the markets are concerned calm has been restored," Madden added.
- Oil helps energy stocks -
On the corporate front Tuesday, the energy sector won support from signs of recovery in the oil market.
"The bounce in oil has boosted shares in the commodity sector and this theme could continue for some time yet," noted Fawad Razaqzada, analyst at Forex.com.
"Oil prices have rebounded strongly over the past three trading sessions on signs that producers are cutting back output."

Spending in 2015 was expected to total about $20 billion, down from a previous guidance of $24-26 billion, BP said in a results statement.
And smaller British rival BG Group revealed it would cut investment by about $3.0 billion this year.
