One of the main benefits is increased investment flexibility. While TSP offers a limited selection of funds, an IRA provides access to a wider array of investment options, including individual stocks, bonds, mutual funds, exchange-traded funds (ETFs), real estate investment trusts (REITs), and even alternative investments such as precious metals and cryptocurrencies through certain custodians. This broader selection allows you to tailor your investment strategy to better align with your risk tolerance, retirement timeline, and financial objectives.
