Will A Spike In 10-Y Treasury Yields Derail The Historic Stock Rally?

  • Rising bond yields have increased attention on 3% as a breaking point for the U.S. stock rally
  • Several factors point to a further rise in bond yields
  • How much is priced in?
  • Risk appetite is more telling than the chicken-or-egg cliché
  • As the yield on 10-year U.S. Treasuries recently spiked to its highest level in nearly four years, murmurs began among traders that the bond selloff—which drives yields higher since they move inversely to bond prices—may be a warning sign that the historic bull market in U.S. stocks could soon be coming to an end.

    While the S&P 500 appears to be able to continue to move higher with no foreseeable end in sight—albeit with some consolidation over the past two days—supported by U.S. President Donald Trump’s recent victory in pushing through tax legislation and hopes that he will, eventually, follow through on his promise to embark on a $1 trillion infrastructure plan, bulls have not been swayed by concerns over a government shutdown. Nor for that matter have they even blinked at the prospect of the more perilous breakdown of trade agreements. Indeed, they've barely stuttered in their move to push stocks to new record highs with a fevered, almost religious chant of “BTFD! BTFD! ” whenever equities dared to take a breather from their hefty climb.

    However, the recent selloff in U.S. government debt, while yet to prove an obstacle for the apparently unstoppable rise in equities, has given pause for thought to some market participants who are observing the upward trend in the 10-year Treasury yield with more than just a little “concern”.

    Often considered the key barometer for financial markets, the yield has spiked more than 30 basis points so far this year (see chart below), breaking above 2.7%, a level not seen since April 2014. Murmurs of warning have begun among some traders, focusing mainly on the 3% level (although over a year ago, analysts from Goldman and JP Morgan penned a now-much-closer 2.75% as the danger zone) as the percentage to watch for when the negative impact could begin on stocks and all signs seem to suggest that the yield will continue to move higher.
