There are always two halves to this, the demand and the value of the money. Demand steadily increases over time, a UBI would cause a spike in that demand so there would be inflation at a higher rate while the market stabilizes. Without an increase in the rate the money is devalued this inflation should stabilize. The problems come when we devalue our money at the same time we're increasing demand causing changes at a rate faster than the markets can compensate. UBI is a shotgun approach and a political tactic rather than a real plan for helping those who need it. A negative income tax and other options that target this help where it's needed would be better options. either way though the trick is to get money where its needed without increasing debt or the money supply while doing so at a rate that doesn't shock the system.
