There were several alleged scams related to corruption and misappropriation of funds that occurred during the UPA government. As per the allegations made by Amit Shah, some of the major scams were:

• The 2G spectrum scam, which resulted in a loss of ₹1.76 lakh crore to the exchequer.
• The coal allocation scam, in which coal blocks were allegedly allotted to private companies without proper auctioning, causing a loss of ₹1.86 lakh crore to the economy.
• The Commonwealth Games scam, in which public funds were allegedly misused to organize the games, causing a loss of ₹70,000 crore.
• The Adarsh housing society scam, in which prime land in Mumbai was allegedly allotted to political and bureaucratic elites at heavily discounted rates, causing a loss of ₹10,000 crore.

These alleged scams caused immense damage to the Indian economy by distorting market competition, fostering corruption and undermining trust in the government. They also eroded public confidence in democratic institutions while exposing the loopholes in governance systems. The UPA government's inability to prevent and punish such scams is widely accused of creating a culture of impunity that allowed corruption to thrive in the country.
