Last month, a working paper from the Bank for International Settlements, the central bank for central banks, cranked up the volume on that warning. In it, Rashad Ahmed and Iñaki Aldasoro calculate that when stablecoins (of which tether is by far the biggest and most impactful) draw in funds, and churn them into reserves, that has a marked impact on the value of short-term US government debt.
That is a reassuring sign that stablecoin operators are indeed buying reserves to match their inflows. Still, this is a substantial and little understood market force. According to the researchers, large inflows of $3.5bn over five days can place enough upward pressure on the price of short-term US government debt to pull down yields by up to 0.025 percentage points over 10 days.
That does not sound like much, but the paper says it is “comparable to that of small-scale quantitative easing on long-term yields” — in the same ballpark as central bank efforts to stimulate a flagging economy
