Wood Mackenzie has cut its global GDP outlook to 2035. China, India and the US sit at the heart of this downgrade. India's GDP growth is forecast to be 5.8% per annum to 2035, down from 6.6% previously. Despite this, India will be the fasting-growing major economy, almost equalling Japan in size by 2035. Similarly, Indonesia is also expected to see robust growth, although improving labour standards will be necessary. In contrast, Brazil and Russia are expected to see weak growth. Ageing demographics and a lack of investment will drag on their economic growth.
