The U.S. central bank's assessment appeared to indicate a slight strengthening of the labour market since it last issued its Beige Book report in mid-January.
"Across the country, contacts observed persistent labour market tightness and brisk demand for qualified workers," the Fed said in the report, a collection of anecdotal information from businesses assembled before each policy meeting.
"Several districts reported continued worker shortages across most sectors," according to the report, which said they were often reported by businesses in the construction, information technology and manufacturing sectors.
The Fed also noted that four of its 12 districts saw a "marked increase" in steel prices due in part to a decline in foreign competition. President Donald Trump announced last week a plan to impose a 25 percent tariff on steel imports.
Overall, U.S. economic activity expanded at a "modest to moderate" pace in January and February and price gains were moderate, the Fed said. Those assessments were similar to those from its prior Beige Book report.
Financial markets expect the U.S. central bank to raise interest rates later this month. Fed policymakers projected three rate increases for 2018 at a December policy meeting. They also raised rates at that meeting.
A range of Fed policymakers have argued in recent weeks that rates need to rise gradually to keep tightness in the labour market from eventually fuelling high inflation.
While the Beige Book report is not a systematic survey, it does reflect each district's sense of the regional economy.
The San Francisco Fed compiled Wednesday's report with information from the central bank's 12 districts collected on or before Feb. 26, 2018.
