Expectations for galloping consumer prices in Argentina remain solidly in triple-digit territory, a monthly analyst poll showed on Friday, though the forecast edged down slightly compared with last month's survey. Analysts polled by the South American country's central bank forecast annual inflation this year at 142.4%, below the 148.9% seen in the bank's previous poll. Sky-high inflation has hammered Argentina's slumping economy, as the ranks of the poor swell and the peso currency steadily weakens.
