No. Interest is a totally different category than stocks or mutual funds. A consolidated form may incldue a 1099-B. 1099-DIV and a 1099-INT, but each category is treated differently.
A mutual fund is a regulated investment company that pools funds of investors allowing them to take advantage of a diversity of investments and professional asset management.
You own shares in the mutual fund but the fund owns capital assets, such as shares of stock, corporate bonds, government obligations, etc. One of the ways the fund makes money for you is to sell these assets at a gain.
If the mutual fund held the capital asset for more than one year, the nature of the income is capital gain, and the mutual fund passes it on to you as a capital gain distribution. Form 1099-DIV, Dividends and Distributions, distinguishes this from other types of income, such as ordinary dividends.
Consider capital gain distributions as long-term capital gains no matter how long you've owned shares in the mutual fund.
