What's a Black budget?
The Budget of 1973-74 is also known as 'Black Budget'. This is because the budget deficit that year amounted to Rs 550 crore. In the Budget speech on February 28, 1973, then finance minister Yashwantrao B Chavan announced nationalisation of coal mines. The decision, many believe, had an adverse effect on coal production in the long run. The finance minister provided Rs 56 crore for the nationalisation of general insurance companies, coal mines, and Indian Copper Corp.
