Stocks flailed to end the month of May and chatter is increasing that rising interest rates could put a damper on what has been an impressive rally in U.S. equities. There is evidence to support the notion that interest rates are on the upswing. On Tuesday, the yield on 10-year U.S. Treasurys hit 2.17% before moving as high as 2.23% Wednesday.

The recent move has been enough to put the yield on the 10-year Treasury note on or close to equal footing with the S&P 500 for the first time this year, William L. Watts reported for MarketWatch.

It is not just previously safe dividend-paying stocks and ETFs that are vulnerable to rising rates. Long duration bonds are sensitive to higher interest rates because bonds issued at new, higher rates apply price pressure to bonds issued when rates were low. The longer a bond’s duration, the more vulnerable it is to rate changes. Reducing portfolios’ duration risk has been a popular theme this year.

“This has been a popular strategy so far this year – flows into fixed income ETFs year-to-date have been primarily into shorter duration ETFs as investors look to cut interest rate risk in their portfolios,” said iShares Head of Fixed Income Strategy Matt Tucker. “Through April 10th, $10.2 billion has been allocated to short duration ETFs while $2.8 billion has been redeemed from longer duration ETFs. Clearly investors are voting with their dollars.”

ETF investors looking for options on the shorter end of the yield curve have plenty of credible options.
