India has built enviable digital infrastructure that will help it achieve the distinction of being the fastest-growing economy in the world for the next 10 years, JPMorgan Chase CEO Jamie Dimon told ET in an interview before the US Federal Reserve's rate hike decision. The springboard for this could be the rerouting of the global supply chain so that companies are not as dependent on China, he said. The US Fed may raise interest rate a lot higher than previously anticipated, making it difficult for the market to adjust, but the greater damage is being caused by geopolitical events such as the Ukraine war and the clouds over Taiwan, he said. Dimon also said the US will be India's best global ally over the next two decades.
