The rally in Italian government bond yields cancelled out a sell-off on Friday ahead of Fitch's review.
Italy's 10-year government bond yield was down nine basis points at 2.765 percent, having touched a low of 2.75 percent, which had pushed its spread over higher rated Germany to a three-week low of 259.5 basis points.
Short-end Italian government bonds also outperformed with two- and five-year yields last down 12 basis points to 0.41 percent and 1.715 percent respectively.
Germany's 10-year government bond yield, the benchmark for the region, was up a basis points to 0.11 percent, while other 10-year yields in the bloc were flat to slightly higher on the day.
Fitch affirmed Italy's rating with a negative outlook to reflect "the extremely high level of general government debt and the absence of structural fiscal adjustment" as well as "uncertainty arising from the current political dynamic."
