Industrial output grew at the fastest pace in 17 months to 8.4 per cent in November, according to government data released on Friday. The previous high was recorded at 8.9 per cent in June, 2016. Economists surveyed by Reuters had forecast 4.4 per cent growth in output, compared with a downwardly revised 2.0 percent year-on-year increase in October. Separately, annual retail inflation accelerated in December to a 17-month high of 5.21 percent, government data showed on Friday, mainly driven by faster rises in prices of food and fuel products. Analysts polled by Reuters had forecast December's CPI inflation to rise to 5.10 per cent from November's 4.88 per cent.
