The Financial Select Sector SPDR (NYSEArca: XLF), the largest  financial services ETF, is lower by 3% over the past month, but some market observers believe the sector warrants renewed attention in the current interest rate climate.

Earlier this year, financials were also propped up by a rise in bond yields as higher interest rates typically widen the margin spread between bank loans and deposits. The spreads will further widen as the Federal Reserve has stated its intentions to raise interest rates in response to economic growth and rising inflation.

A steeper yield curve could help XLF and rival financial services ETFs rebound.

“Banks get squeezed as a yield curve flattens, since they typically take on short-term debt to fund longer-term loans, and profit from the gap between the two rates. Conversely, a steeper yield curve would boost the margin,” reports Evie Liu for Barron’s.

Looking for Financial Catalysts

Fundamental factors, including the aforementioned rising interest rates, have been supportive of bank stocks and ETFs this year. Additionally, the financial services sector, the second-largest sector weight in the S&P 500, has had the regulatory wind at its back this year as the Trump Administration has sought to roll back parts of the Dodd-Frank legislation. Still, the sector is disappointing investors.
