eventually, the carry will unwind and debt needs to be refinanced more QE-like measures will be taken, but eventually it won't be enough to prevent deleveraging/burst. this means defaults, margin calls, etc. the latter will likely be addressed by another form of QE
in conjunction, this creates an upward pressure in the global liquidity for the near future of course, this also builds up on leverage in the form of market-wide carry trades, and duration mismatching in the form of rolling over of debt by the Treasury
