I remember finding this word in P. Spufford's Power and Profit, and now can't read it without once again fruitlessly checking reverse dictionaries.
It was used to describe a mass revival of investment after a downturn, and was either in the context of, or specifically referred to, removal of money stored in chests. I doubt it was divest or another common word; it could well have been a compound of re-, dis- or de-.
