Traders sometimes get sloppy with relationships, especially when they work superficially. One of those has been the relationship between the yield curve, specifically the spread between the yields on 2 and 10-year Treasury notes. There is logic to the idea that banks benefit if that spread widens. Banks tend to borrow short-term via demand deposits and the money markets and lend long-term via mortgages and commercial loans. It, therefore, makes sense to think that a steepening yield curve benefits banks’ profits.

For most of the time since the Federal Reserve began its post-Covid monetary stimulus in March 2020, KRE, the SPDR S&P Regional Banking ETF, has been moving in tandem with the 2/10 spread, as shown below:

We see the two lines moving in near lockstep until last summer. At that point, KRE largely continued higher even as the 2/10 spread narrowed, and in recent weeks we have seen KRE remain solid even as the spread plunged. That is wonderful for those who have been long regional banks but upending what appeared to be a solid trading relationship.

I believe there are two main reasons for the recent outperformance. First, equity markets overall have been robust. That makes investors more willing to overlook potentially detrimental news. But the second reason is better explained by the following graph:

We see that KRE has begun to follow 2-year yields higher even as the spread with 10-year yields narrowed. There is a logical reason for this change in focus. While the 2/10 spread is a convenient shorthand for the spread relationship that banks utilize, it is not fully descriptive. Think about your checking account at a bank. You have likely not received a bump in the rates that you receive on the funds in your account, but the bank has likely received a boost in the amount that they can reinvest those funds in safe short-term assets. They are now able to earn a reasonable spread on customer deposits, which flows to the bottom line.

Some of you may be wondering why we have chosen to focus on KRE rather than XLF, the Financial Select Sector SPDR. The reason is that XLF is by no means a pure-play on banks. There are many non-banks represented in the ETF, including its largest holding, Berkshire Hathaway (BRK-B), and others like Blackrock (BLK), Charles Schwab (SCHW), S&P Global (SPGI), and American Express (AXP). Furthermore, the “money-center” banks that are in this ETF are more dependent upon capital markets, investment banking, custody, and other activities. Compare the relative performance of XLF to KRE and the 2/10 spread since April 2020:

XLF has been a steady performer, but not nearly as strong as KRE and not nearly as tied to the 2/10 spread. That said, XLF has benefitted from the rise in 2-year yields for the same reason that KRE did. Many of these companies borrow with demand deposits that have not risen along with their ability to invest these funds at better short-term rates:

The takeaway for traders is this: even if narratives produce consistent tradeable relationships, those relationships can change without warning. In this case, the break between KRE and the 2/10 spread, which had been rock solid, still benefitted those who were long KRE. It wasn’t that the relationship failed, it simply became more nuanced. And for those traders who applied the same logic that worked for KRE to the superficially similar XLF, the relationship was not nearly as fruitful.
