Tushar Pendharkar, head of research, Right Horizons Investment Advisory Services, said most of the major economies, such as Australia, Brazil, West Asia, Russia and Africa are commodity exporters; and continued pressure on global commodity prices is impacting their GDP growth.These economies are struggling to sustain positive GDP growth and the risk of subdued global demand is rising. Therefore, exports from India and China to these countries are slowing down.India’s private sector is still reluctant to invest due to the cautious global scenario. Excess corporate debt is slowing down credit growth and impacting non-performing assets (NPAs). Thus, banks are hesitant to provide higher credits to the core sectors of the economy “Most of the sectors, especially capital goods and infrastructure, are in the middle of their balance sheet cleaning and thus it is still very early for them to raise funds for new projects. This situation is also impacting capital expenditure-linked demand, which includes metals, cement, labour,” he said.
