Market analysis

Experts attribute market fall to geopolitical tensions and inflation fears

Ajit Mishra, SVP of research at Religare Broking Ltd, attributed the market downturn to lingering geopolitical tensions in West Asia, a weak rupee, and rising inflationary concerns. He said the sharp rise in crude oil prices above $105 per barrel has intensified fears of imported inflation, fiscal stress on the economy, and pressure on corporate margins.
