(Adds clarification on unanimous decision, analyst comment)
MEXICO CITY, April 4 (Reuters) - Most of Mexico's central bankers think that a spike in inflation has likely passed, while the majority said short-term risks to growth would push them to cut their growth outlook, minutes released on Friday showed.
Central Bank board members voted at their March 31 meeting to hold their benchmark interest rate at a record low of 3.50 percent.
The minutes did not specify if the decision was unanimous or not, a rare omission for the bank. The central bank later issued a statement clarifying that the decision was unanimous, 5-0.
Most policymakers said that the risks of higher inflation had receded marginally, while the majority thought the bank would have to revise down its current growth outlook of between 3 percent and 4 percent for 2014.
"The majority of board members thought that the balance of risks to growth had deteriorated, on the margin," the minutes said, with most board members adding that recent economic reforms improved the medium-term growth outlook.
Analysts expect the bank will hold borrowing costs steady this year as the economy recovers from a weak start to 2014.
"The minutes confirm that the economic environment does not suggest an imminent change in monetary policy," Barclays analyst Marco Oviedo said in a report. "Growth is the main concern, but not enough to trigger a reaction."
Most of the policymakers said there was no evidence that taxes introduced this year were spurring wider price pressures. Data late last month showed annual inflation fell back below the bank's 4 percent ceiling in early March.
But some members said taxes could still drive so-called second round effects on prices, while more global volatility could hurt the peso and drive up inflation by making imports more expensive.
Mexico's peso slumped early this year on fears about less U.S. monetary stimulus and a global sell-off in emerging markets. But the currency hit a nearly 3-month high on Friday after solid U.S. jobs data boded well for local exports.
Banco de Mexico Governor Agustin Carstens said on Thursday that the economy is starting to grow more quickly, while inflation will head toward 3 percent over the next 18 months.
Since the March 21 decision, data has shown that factory exports rose at their fastest pace in more than four years, while March consumer confidence data jumped.
Analysts cut their growth estimates for growth this year to 3.09 percent, a poll from the central bank showed on Thursday. (Reporting by Michael O'Boyle and Luis Rojas; Editing by Dan Grebler)
