Does one need an account in a Bank to invest in its Mutual Fund?

In general, yes, you will need to have a bank account with the bank that offers the mutual fund in order to invest in it. This is because mutual fund investments are typically made through the bank's investment platform, and the bank needs to be able to process your investment and facilitate the transfer of funds.

However, some banks may allow you to invest in their mutual funds without a bank account if you use a third-party investment platform that supports the mutual fund. Additionally, some mutual funds may be available for purchase through other investment platforms or brokerages, regardless of whether or not you have a bank account with the bank that manages the fund.

It's important to do your research and understand the specific requirements for investing in a mutual fund before making a decision. You can typically find information about the requirements for investing in a particular mutual fund on the bank's or investment platform's website, or by contacting their customer service department.
