BRASILIA (Reuters) - Brazil's central bank is expected to maintain its moderate pace of interest rate cuts later on Wednesday despite a sharp economic contraction in the third quarter that suggested a grueling recession could extend into a third year.
Brazil's economy shrank for a seventh straight time in the third quarter, further raising pressure on the bank to keep loosening monetary policy after it cut rates for the first time in four years at its last meeting.
But market turmoil triggered by the election of Donald Trump to the White House and a political scandal at home have investors betting on caution.
Fifty-four out of 64 analysts surveyed by Reuters believe the bank will cut its benchmark Selic rate <BRCBMP=ECI> by another 25 basis points to 13.75 percent, its lowest in over a year. The rest forecast a rate cut of 50 basis points.
Economic output shrank 0.8 percent in the third quarter from the second, statistics agency IBGE said on Wednesday. There were no bright spots as investments dropped sharply, farmers, manufacturers and service providers all reduced production, and families and government agencies consumed less.
"Fourth-quarter numbers do not give much reason for optimism either. Confidence indicators are signaling they could fall, reflecting some disappointment with how long the economy is taking to lift off," said Newton Rosa, chief economist at SulAmerica Investimentos.
The government last week cut its 2017 growth estimate to 1 percent from 1.6 percent, but some analysts do not rule out a third year of recession with lingering doubts over the government's capacity to shore up its depleted public accounts.
Following Trump's surprise victory on Nov. 8, market volatility spiked on expectations his promises for fiscal stimulus could raise U.S. interest rates and spark a flight of capital from riskier markets. The Brazilian currency <BRL=> has dropped by more than 6 percent this month, adding pressure on inflation that, despite a recent slowdown, remains well above the 4.5 percent target.
More recently an ethics scandal within President Michel Temer's cabinet has raised fears he could lose support in Congress to push ahead austerity reforms needed to allow the central bank to keep lowering some of the world's highest interest rates.
Even after the Senate approved Temer's proposal to cap federal spending in a first-round vote late on Tuesday, violent demonstrations outside Congress rekindled fears of more street turmoil ahead.
Most analysts predict the bank will wait until its next meeting in January to accelerate rate cuts in the face of what could be the country's worst recession on record.
"One possibility is that the board will cut by 25 basis points again but adopt more dovish language, to start paving the way for a faster rate-cutting pace next year," analysts with BNP Paribas wrote in a research note.
