The correct preposition, which should be used here is 'for' as it is given that 'the supply has been lowest for some period of TIME'.

Usage of 'for': We use 'f$or' when we MEASURE the duration – when we say how LONG something lasts.$

Hence,$For + a period of time.

For example: I $have lived here for ten years. $

Usage of 'since': '$Since' gives the starting point of actions, events or states. It REFERS to when things began.$

Hence, Since + a point in time (in the past), until now.

For example: I have known him since JANUARY.
