"The medium-term implication is therefore less “lower yields” than “a more managed yield curve”. Call it YCC-light. The Treasury has shown sensitivity not only to poor liquidity, but also to the economic and political consequences of rapidly rising long-term yields. Thirty-year rates above 5% feed into mortgages, corporate financing, equity valuations and, through higher interest costs, the deficit itself. That creates a feedback loop: higher yields worsen the fiscal outlook, which warrants a larger term premium, which raises yields further. Wednesday’s intervention interrupted that loop; it likely did not break it." - Rabobank(zerohedge)
