GSIB vs IAT

GSIBBThemes Global Systemically Important Banks ETF

IATDiShares U.S. Regional Banks ETF

In short

GSIB Most bank ETFs stop at the US border. GSIB goes after the other kind of bank: the world's systemically important ones, roughly 30 global megabanks in a single actively managed portfolio.

IAT Regional banking, undiluted: about 30 U.S. lenders, no insurers or brokers padding the basket, from an iShares fund that has been on the tape since 2006.

Stated mandate

GSIB The Fund seeks growth of capital through an actively managed portfolio of equity securities issued by companies operating in the global banking sector.

IAT The Fund seeks to track an index of U.S. equity securities from the regional banking sector. It uses representative sampling to pursue index-like investment characteristics rather than necessarily holding every constituent.

Why people hold it

• GSIB The niche is in the name: global systemically important banks, roughly 30 of them, rather than another basket of US regionals.
• Genuinely global mandate. Most of the bank-ETF field is domestic (KBE, KBWB, KRE) or single-region (PBEU, European banks).
• 0.35% expense ratio, right at the bank-ETF median, and you get an actively managed global sleeve for it instead of a plain index tracker.
• Spread across megabanks in several regions, so no single country's banking system runs the whole fund. It grades out in the upper half of its bank-ETF peer group.

• IAT Narrow by design: roughly 30 U.S. regional bank stocks, not a broad-financials grab bag.
• Launched in 2006, so it has traded through multiple bank-stress cycles rather than arriving after one.
• Pays quarterly and tracks a published benchmark, the Dow Jones U.S. Select Regional Banks Index, so the mandate is easy to check.ishares.com

Worth knowing

• GSIB Launched in 2023, so the live record is short and the asset base is still small next to the established bank ETFs.
• Thinly traded for its category. Spreads can widen, and limit orders do the heavy lifting.
• One sector, roughly 30 names, and distributions land once or twice a year rather than monthly.

• IAT The 0.37% fee sits a notch above the going rate in bank ETFs; peers KBE, KBWB and KRE each list 0.35%.
• One sector, one country, about 30 names. Rate swings and credit scares land here with nothing else in the basket to absorb them.
• It samples the index rather than holding every constituent, so results can drift from the benchmark.ishares.com
