Banana Investments Advisory is the Banana Farm's path 2 tier 4 upgrade in Bloons Monkey City. In the mobile version, it increases its cash generation to 100 packets of $10 per round, increases its interest from 10% per round to 20%, and increases its capacity from $5,000 to $20,000. In the Flash version, it increases its cash generation to 50 packets of $30 per round and increases its capacity from $7,500 to $30,000. Crosspathing with More Bananas increases the number of cash packets generated per round from 100 to 104 (50 to 52 in the Flash version), and Banana Plantation further increases it from 104 to 118 (52 to 59 in the Flash version).

The BIA is simply not worth it due to the lowered round count of tiles compared to Bloons TD 5, making withdrawals much more risky due to lack of reinvestment speed. Even with Monkey Knowledge, there is no point in getting this upgrade, as the interest on the cash on hand is immediately added to the cash total, not placed into the bank as interest. The money invested into BIA is better spent into Banana Research Facilities instead.
- This is the only tier 4 upgrade that does not require a Special Building to be built. Internally, it requires a Monkey Bank building to be built, but it is impossible to not have this building since the player always starts with one and the last Monkey Bank cannot be destroyed.
