Crude prices have been squeezed after OPEC declined to constrain production last week despite global oversupply and slowing growth in the eurozone and China. On Tuesday, West Texas Intermediate crude slid nearly 3% to $67.30 a barrel on Tuesday, around 36% lower than its mid-summer high.
"The suppliers are going to start restraining production at some point," predicted David Bechtel, principal of Barrow Funds, in a call. "They're going to want to see oil get back up into the mid-$80s, low-$90s minimum. It's probably a project that occurs over the next 12 to 18 months."
If plunging prices continue, though, some of the top dogs at the Federal Reserve don't seem fazed. Speaking at separate events Monday, New York Fed President William C.

It "will lead to a significant rise in real income growth for households and should be a strong spur to consumer spending," said Dudley, speaking to an audience at New York's Baruch College.
