Treasury yields reached fresh all-time lows Friday, tumbling for the sixth straight week even as June's official jobs report suggested that the U.S. economic expansion remains intact.

Treasurys initially sold off after the data were released, pushing yields higher as the strong report was interpreted as potentially setting the table for the Federal Reserve to raise interest rates in the near future.

The move higher was most pronounced in short-term Treasury yields, which are most sensitive to changes in the federal-funds rate and tend to spike when investors expect that rates will rise sooner rather than later.

On balance, the yield on the 2-year note TMUBMUSD02Y, +7.88% gained 2.4 basis points on the day and 2 basis points over the week to 0.613%, a ten-day high. Bond yields and prices move in opposite directions.

But long-term yields wavered, inching higher shortly after the release and tumbling later to end the week at fresh record lows for both the 10-year and the 30-year benchmarks.
