The coronavirus-fueled slide in Treasury yields may have triggered a phenomenon known as convexity hedging -- which also means there could be further downside.

The 10-year yield had held within a range of about 1.70% to 1.95% since October, before heading lower late last week as concerns about the spread of coronavirus from China sent investors searching for safe havens. The break below 1.70% on Friday appears to have spurred convexity hedging flows from a variety of market players, adding fuel to the rally, according to TD Securities. What’s more, those flows may exacerbate further declines in yields.
