BTG Pactual offers a relatively low-cost structure compared to many other brokers, especially when it comes to its custody and maintenance fees. For most investment products, such as fixed income, treasury direct, and investment funds, there are no custody or maintenance fees, which is a huge plus for long-term investors who want to avoid unnecessary costs. The brokerage fees are charged regressively, meaning that frequent traders will pay lower per-order fees, which encourages active trading. However, it is important to note that certain services come with higher costs, such as margin interest rates for products like Invest Flex, which charge an interest rate of 5.99% per month. Additionally, there are brokerage fees of 0.5% for cryptoassets. In my opinion, the lack of maintenance fees for most products is a major advantage for investors who prioritize low-cost investing, especially for those who plan on holding assets for extended periods. However, the relatively high interest rates for margin products and the crypto brokerage fee could be a deterrent for traders who are looking to use leverage or trade in crypto. If you are an active trader or someone who uses margin frequently, these fees might add up quickly, which is something to consider when choosing BTG Pactual.
