Moreover, stronger inflation numbers should give the Federal Reserve confidence to raise interest rates this year at a steady clip, which can also be bearish for bonds.
Traders are closely eyeing the inflation data to see if the rise in investor-based gauges of inflation expectations, as measured through Treasury-inflation protected securities, or TIPS, will come to fruition. Break-even rates have risen to 2%, the central bank's price target. Amid talk of whether a bear market in bonds is nigh, a resurgence in the consumer-price index would add to the growing feeling that the 10-year Treasury yield will finally break higher in 2018, after doing little last year.

What did market participants say?
