After many months of expensive pricing relative to treasuries, municipal bond prices began to capitulate this week. Together with treasury price weakness, longer term municipal bond prices are breaking down with yields jumping upwards.

Last month we discussed that the bond market correction was hanging on by a thread. By mid-month it appeared the correction phase was intact as ten-year treasury yields moved from 4.73% on April 25^th to 4.31% on May 16^th (all prices and yields per Bloomberg). The spirited move saw some sympathy with two-year treasury notes (from 5% down to 4.70%), but just a few days later the two-year note is back to 4.95% on May 24^th.

Remember, it is the shorter-term treasury yields that shape Federal Reserve policy, not the other way around. With short-term treasury bills and two-year notes at or near their highest yields for the year, this trend is not encouraging.

If there is such a thing in the bond market as everyone on one side of the boat, it is the duration trade. With yields on bonds at levels investors have not seen in years it seemed to make sense to buy some longer bonds to take advantage when the Federal Reserve lowers interest rates again. This could help explain bond prices rallying nicely in last year’s fourth quarter. Municipal bonds were trading about 75% of treasuries (ten-year maturity basis) to begin the move in October and later hit a record low of 57% in March, further amplifying municipal bonds bounce up in prices.
