On average, CFOs are less than 21 percent confident the Trump administration would be able to pass reforms to overhaul health-care in 2017. When asked this question three months earlier, the average confidence level was 41 percent.
Responses to the CNBC Global CFO Survey are anonymous. All 35 CFOs who completed the survey responded to this question.
The U.S. Senate failed to pass various forms of health-care this summer, prompting Trump to blame Republican leaders for a legislative "mess."
However, aside from the health-care debacle, the White House currently appears to be prioritizing tax reform. Treasury Secretary Steven Mnuchin described this as the Trump administration's number one priority.
Speaking at CNBC's "Delivering Alpha" event on Tuesday, Mnuchin reiterated his confidence about getting a tax reform bill to the president's desk in 2017. "We're going to get this done by the end of the year," he said, adding the White House is "super focused" on this issue.
Global CFOs were less optimistic.
"What we have seen in the previous surveys of the Global CFO Council is that businesses were somewhat skeptical about the abilities of Donald Trump to move the reform agenda forward... What we see right now is that they are becoming even more skeptical," Evgeny Fetisov, chief financial officer at Luxoft, told CNBC on Friday.
"Initially people were not too optimistic about 2017, but it looks like we will see less action going forward in 2018 as well," he added.
Respondents of the CNBC Global CFO Survey said they were doubtful either personal or corporate tax reform would be passed into law in 2017. On average, their confidence in tax reform is less than 40 percent for either measure.
