Investors with over $250,000 are increasingly turning to separately managed accounts, allowing them to handpick municipal bonds with professional guidance. These accounts now hold $987 billion in assets, surpassing mutual funds, which hold about $769.7 billion.

This shift has significantly boosted business, with Franklin Templeton seeing a 50% increase in assets under management over the past year and a half. Lowering the minimum investment to $250,000 has made these accounts more accessible, though still beyond the reach of most Americans. 

However, advancements in technology are driving further accessibility, with potential for minimums to drop to $100,000 in the near future. With artificial intelligence breaking down barriers by making management for portfolio quicker to digest the minimums are bound to fall.
