This being the last day of the week I expected prices to come down on profit-taking.

The IAEA meeting is paramount on investors' minds, because it has the potential to alter the demand supply equilibrium.

Asian central banks have been huge buyers of Treasuries, so if they're going to be buying less to hold down their currencies, then Treasuries will fall.

Prices haven?t fallen by much because of the heavy refinery maintenance seen around March, which still raises some concerns over supply particularly for gasoline.

The IAEA meeting is paramount in investors' minds, because it has the potential to alter the demand-supply equilibrium.

The situation between Russia and Ukraine is a rather (supportive) factor for oil ... as the potential for (gas) supply disruption in Europe is having a correlating effect on other energy commodities including oil.
