Past demonetization efforts, such as India's 2016 demonetization of ₹500 and ₹1,000 notes, offer several lessons. One key takeaway is the importance of thorough planning and communication. Clear messaging about the reasons for demonetization and the expected outcomes can help mitigate public anxiety and confusion. Additionally, ensuring that adequate banking infrastructure is in place to handle the surge in transactions is crucial. Furthermore, it highlights the need for complementary measures, such as promoting digital payment systems and enhancing financial literacy, to ensure that the population can adapt to the changes effectively.
