What causes all units to no longer be able to move?

[Tanaka]

I'm in supply and have oil?

[eddieballgame]

Well, for starters...no 'Action Points' & or 'No Food'.

[Destragon]

Uh, I guess you don't have movement mode active?
No way to tell without screenshots.

Actually, you say ALL units can't move anymore, then it's probably the movement mode for real. Press m to turn on movement mode.

[eddieballgame]

Yes, if you are on 'Inspect' or 'Construct Road' for example, that will...slow you down. [:)]

I've accidentally spent all of my IP building a road to nowhere when I just wanted to move my Militia to scout the nearby hills.

Yes, I have built a couple of 'roads to nowhere'. (not worth going to) [:)]

UI is not most obvious at times.

...'No Food'...

Yep, I learned that one the hard way!

Just a general FYI - in addition to the keyboard shortcut 'm' key, Move mode is also assessible in two other ways, via a menu button on the right side of the screen and via a popup dialog on mouse right-click.
