I will grant that the saddle position can affect relative pressure that one must place on the handlebars, but it has no direct effect on circulation in the arms or fingers per se.
To the actual problem, and why it is happening now, I can only offer speculation that something has changed. What it is, I don't know. Maybe your bar tape is compressed and hard. Maybe you changed your pedal system, and your relative height is higher, putting more forward pressure on the bars. Maybe you changed the bar angle.
