I guess this is a contraction of "upward revaluation" and used in financial areas. Does anyone here know this? Is it only used with regard to monetary value or could it mean "increasing importance". What happend to all the charming portmanteau words - hey?! This one does fill in a gap though, as far as I can tell, or can someone suggest another single word for this?

I haven't heard it before, by, and am having trouble finding any distinction between it and valuation (as opposed to devaluation).

Yeah, Chris. I work in the financial services sector, and this has to be an A-grade transpondialism. We use "revalue" as a verb, but "valuation" as the noun ...

I think that in Big Economics, this has to do with making a national currency better, stronger, more acceptable, somehow, but what I know about economics can be conveniently written on the average cocktail napkin.

looks like this a standard economics formulation:

"We think ultimately that disinflation triumphs over reflation," - MSN Money

Chrispy, I thought of your word when I heard the term 'downsize' today. A similar formation, no?

<can be conveniently written on the average cocktail napkin>

You ever tried writing on a cocktail napkin? It's really difficult and quite inconveniently they're often red or some dark colour...

I have seen upvaluation used interchangeably with upgrade - both common problem in schools fighting grade inflation. I have been asked to reconsider my grade and upvalue a trainee's performance (I'm a strict grader...).
