If anything, it would just inflate currency further, because investing 5m gold at 3%/month or whatever creates raw gold out of nothing.
I completely agree with your goal here, removing money from the economy, but that isn't the way to do it. The way to do it is for Blizzard to announce that they're adding 4 completely unique, awesome-looking mounts to the game. Two are BoP costing 50k gold apiece, and two are BoE and cost 500k gold. And then there's the kicker-- upon the release of patch 9.2, these mounts will be removed from the game and will NEVER be available again. Blizzard commits to them never going in the BMAH either.
The end result is poor folk will buy the 50k mounts. Rich people will buy the 50k mounts for themselves and then spend all their liquid cash to hoard multiple 500k mounts, because they know prices will go up in the future-- the mounts look cool and new supply will be reduced to 0.
This will permanently remove tons of money from the economy, a strongly deflationary measure, and most importantly it's progressive-- it primarily takes money from rich people, not poor ones. I would certainly get maybe 10 of those 500k mounts myself, plan to put them in the bank for a couple years.
