Trade options betting both in favor and against the SPDR S&P Regional Banking ETF (KRE) hit record levels in March as traders speculate on the industry’s future following the recent crisis. Since the start of the banking crisis in mid-March, daily trading volume for KRE hit a record trading volume $4.9 billion, and the fund is set to hit its biggest monthly volume since it was created in 2006. With holdings in New York Community Bancorp and Regions Financial Corp, KRE whipsawed as investors waited in anticipation for the U.S. Senate hearing on failures in regional banks. At its lowest, the fund plummeted nearly 30 percent during the period.
