Today It’s the Banks’ Turn, But That Harbors a Risk


Chief Strategist at Interactive Brokers

Like many, I have a go-to market watchlist page.  Mine is headed by the major indices and their futures, followed by key stocks and sectoral ETF’s.  This allows me to better understand why the market is moving up or down on any given day.  Today’s screen showed yet another rally in the broad market indices, with the S&P 500 (SPX) outperforming the NASDAQ 100 (NDX).  The reason is that the leadership has shifted to an often-unloved sector – the banks.

I wish I could enjoy the re-emergence of that sector without worrying about the reasons behind it.  These companies have valuable franchises and are leveraged to an economic recovery.  Problem is, that recovery is reflected in a steeper yield curve.  That sounds benign, but as banks benefit from a steepening curve, the rest of the market could suffer.

When we discuss a steeper yield curve, that refers to the difference in yields between short- and long-term fixed income securities.  In the case of US banks, the relevant benchmark is the difference between 2 and 10 year Treasuries.  That spread is relatively tight by historical standards but is relatively high by a recent metric.  It has actually increased during Covid, since we saw an inverted curve prior to the monetary response to the pandemic.  The change is almost exclusively at the long end of the curve.  The short end has remained relatively fixed, with the Federal Reserve’s continued assertions that they will be slow to raise interest rates. 

Banks love a steeper curve because they tend to borrow short and lend long.  This is a gross oversimplification, but banks tend to borrow via checking and savings accounts and in other short-term deposits and lend via mortgages and corporate loans.  The former group is short-term (you can remove your savings with no notice, but the rate is about zero), while the latter is longer-term (mortgages are usually 15-30 years and while rates are low, they are not about zero).  If banks face little pressure to raise the interest rates that they offer on demand deposits but have room to raise the rates they charge on loans it is highly beneficial to their bottom lines.

Here’s the rub.  Consider this graph:

This graph displays the price of 10 year Treasury bond futures.  Remember that bond prices move inversely to yields.  We can see that the massive rise in T-bond prices seems to have ended, and may be rolling over.  Today’s investors in financial stocks are banking on the idea that yields could continue to rise.  We can see that there is plenty of room for that.  A return even to pre-Covid levels would push long-term rates by 50 basis points or more.  That would be good for a bank’s income statement.

Yet a rise in rates could be perilous for the market as a whole.  A broad range of investors have used low interest rates to justify historically high stock valuations.  If those valuations are threatened by rising rates, it could pose a real headwind for a market that is top-heavy with high P/E names. 

We find ourselves with a fascinating conundrum.  Markets are anticipating a stronger economy as we emerge from the pandemic.  That anticipation is reflected in high stock prices and rising bond yields.  The problem becomes, if the economy is strong enough to boost bond yields sharply, that could impede the stocks that base their valuation on low yields.  It is rational for investors to hedge that risk by rotating into stocks that could indeed benefit from rising rates.  Banks fit that bill. But this healthy rotation could indeed be the harbinger of something more worrisome.
