Russian pig iron exports have come to a halt due to the strengthening of the rouble. The stronger currency has made Russian pig iron less competitive in the global market, leading to a significant decline in exports. This situation has been exacerbated by the ongoing geopolitical tensions and economic sanctions imposed on Russia, which have further strained the country's export capabilities. The impact of these factors has been felt across the industry, with many exporters struggling to maintain their market share and profitability.
