New Delhi, 31 August (NNS): After a modest rise in large cardamom prices in recent days, buying demand has weakened. As a result, big cardamom kainchicut prices have fallen by Rs 95 within a week to Rs 1580/1585 per kg. Traders and stockists are adopting a cautious approach amid expectations of the arrival of the new crop, affecting both buying and selling activity. Production is expected to be better this year, while traders already hold sufficient stocks, preventing prices from rising. Demand from wholesalers and stockists remains weak. Prices have also declined from elevated speculative levels. Given weak demand and expectations of new-crop arrivals, there appears to be little scope for a rise in the coming days.
