Spread bets and CFDs on the U.S. stock market should consider that futures are a little bit higher today. Last Friday, U.S. stocks came back late in the session to sqeeze out the tiniest of gains, and bulls look to be trying to add a little momentum for this week.

Earlier today, U.S. stock futures were lower, but they have since inched higher, following European markets as they move every so slightly into the black. Treasury Secretary Timothy Geithner vowed that the U.S. would not lose its AAA bond rating, and developed nations pledged reforms to prevent another global financial crisis.

Also over the weekend, G-7 countries decided to forgive Haiti's foreign debt. We'll have to wait and see how things go today in order to determine where the investors will take the U.S. stock market.

Spread bets and CFDs on the European stock market should consider that European stocks are moving into the black as the trading day draws nearer to an end. After falling earlier in the session, major stock indices in Europe are moving higher.

Concerns about sovereign debt in Greece, Spain and Portugal were dragging major markets down, but Europe's leading indices, including the CAC 40 and the DAX have managed to move slightly out of the red.

The FTSE 100 is also marginally higher, overcoming earlier losses to pull in some gains in late trading. What happens in the early portion of the U.S. session will probably help determine whether or not the FTSE 100, along with European markets, remain in the black.

One of the big issues recently has been that of sovereign debt. Debt concerns in Greece have many thinking about where else such problems could arise. Indeed, there are many developed countries that are seeing an increase in sovereign debt as a result of economic stimulus borrowing.

Those countries include Britain and the U.S. After watching what has been happening in Greece, some are concerned that the U.S. and Britain might have taken on more debt than they can handle. As a result, concerns about sovereign debt are becoming a focus.

However, few are terribly concerned about Britain the U.S. yet. For now, additional sovereign debt concerns are mostly focused on Portugal and Spain. These countries have high amounts of debt as well, and appear to be approaching the same situation as Greece.

Unless countries can get their spending under control, and get their debt sorted out, it could be another global financial crisis.

Spread betting and contracts for differences on commodities should consider that oil prices are moving higher today. After falling in the previous session, oil prices are attempting to make up some lost ground.

However, oil prices are seeing limited gains as weak demand continues to cause issues. With the global economy still not increasing the amount of oil it uses, it is difficult for oil bulls to justify sending prices higher.

Until the global economic concerns are truly ironed out, it is unlikely that oil prices will see a significant recovery.
