We’ve been talking on and off for the past year or so about the fall in oil prices. Fine. Old news.

Bloomberg went out and did a little math though and came up with a really big number. The fall has wiped $1.3 trillion off the value of energy companies as their share prices have fallen along with crude.

That’s a number so big it kind of doesn’t mean anything … ’til you think about all the pension funds and retirement accounts that have those company shares in their portfolios.

Crude today is $44.50 a barrel.
