Inflation nerves return US yields rise, boost dollar The inflation genie I mentioned on Friday found life rather uncomfortable in its bottle, it appears, as US yields shot higher on Friday. Notably, the long end of the curve steepened markedly, and for all the noise surrounding the rise in 10-year yields, the 30-years was where the real action was. That was enough to unwind the intra-day rallies on Wall Street, with the rotation into cyclicals at the expense of technology very much in evidence again. That left the Dow Jones higher, the Nasdaq stretchered of injured once again, and the S&P 500 left somewhere in the middle.
