There's not much that can pry investors' attention away from the fireworks in the stock market this year — but a big jump in Treasury yields will do it.
A springtime swoon in the bond market pushed yields on 10-year Treasury notes to nearly 4.7% in mid-May before they settled back to 4.45% by the end of the month. (Prices and yields move in opposite directions.) That's up from 3.96% before the start of the war in Iran — a big move for bonds.
