This isn't really true. Inflation is defined as the cost of purchasing necessities (for a specific set of necessities designed by the BLS - basically housing, food, medicine, etc).
If a BI shifted spending from investment/savings to consumption, demand for necessities would increase, driving up the cost. I.e., inflation.
Also, there is another structure which distorts the market even less than Basic Income. It's called the Basic Job. You get a Basic Income, but you need to show up and do work to receive it. It solves all the same problems as Basic Income, but with far lower disincentive for work, and at far lower cost.
