If one end of the balloon is squeezed, making the volume smaller, the pressure inside increases, making the un-squeezed part of the balloon expand out. The real issue is not how criminals transfer their illegal earnings; it is the criminals themselves. Hence, the policy decision on this issue needs to be carefully considered.

Firstly, there are no records of the Undiyal agents or the volumes of transactions publicly available. However, comprehending the scope of the underground operation that exists in the country is quite difficult. Practical implications - The study contributes to the academic researchers grasping what type of future research should be focused on in this area according to the study. Social implications - From the point of view of its practical application, the study seeks to resolve social issues that the middle-class population experiences on a daily basis and that have a huge and adverse impact on GDP. Originality/value - To the best of the authors’ knowledge, this is an original contribution.
