Interest spreads hold sway over the global economy

An inverted yield curve is a reliable predictor of recessions but it also warns of falling bank profits. When the spread between long-term Treasury yields and short-term rates is  below zero, net interest margins are squeezed.

Yield Differential (10y - 3m)

In a normal market, with a steep yield curve, net interest margins are wide as bank’s funding maturity is a lot shorter than their loan book. In other words, they borrow short and lend long. Few bank deposits have maturities longer than 3 to 6 months, while loans and leases have much longer maturities and command higher interest rates.

When the yield curve inverts, however, the spread between long and short-term rates disappears and interest margins are squeezed. Not only is that bad for banks, it’s bad for the entire economy.

When their interest margins are squeezed, banks become risk averse and lending growth slows. That is understandable. When interest margins are barely covering operating expenses, banks cannot afford credit write-downs and become highly selective in their lending.

Slowing credit growth has a domino-effect on business investment and consumer spending on durables (mainly housing and automobiles). If there is a sharp fall in credit growth, a recession is normally not far behind1.

Bank Loans & Leases

Right now, the Fed is under pressure to cut interest rates to support the US economy. While this would lower short-term rates and and may flatten the yield curve, cutting interest rates off a low base opens a whole new world of pain.

Quartz this week published a revealing commentary on the damage that negative interest rates in developed economies are doing to bank net interest margins :

The problem for commercial banks is that government bond and mortgage interest rates keep going lower, but it isn’t as easy to cut deposit rates — the rate at which banks themselves borrow from customers — at the same pace. After all, it’s tough to convince people to keep deposits in an account that returns less than they put in (even though this already happens, invisibly, through inflation).

Bank Net Interest Margins in Developed Countries

Ultra-low interest rates are likely to squeeze bank margins in a similar way to the inverted yield curve. And with a similar impact on credit growth and the economy.

If I was Trump I would be pleading with the Fed not to cut interest rates.

1. The NBER declared a recession in 1966 when the S&P 500 fell 22% but later changed their mind and airbrushed it out of history.

Inverted yield curve is no cause for panic….yet

10-Year Treasury yields continue to fall. A Trend Index peak below zero signals strong selling pressure (purchases of bonds).  Target for the decline is primary support at 2.0%.

10-Year Treasury Yields

The spread between 10-Year and 3-Month Treasury yields is at zero, warning that the yield curve is about to invert. While there is no cause for panic, an inverted yield curve is a reliable predictor of recession within 12 to 18 months, preceding every recession since 1960*.

*1966 is an arguable exception. Initially classed as a recession by the NBER, it was later reversed and airbrushed out of history.

10-Year minus 2-Year Treasury Yields & Bank Credit

The 10-year/3-Month spread last crossed below zero in August 2006 and was followed by a recession in December 2007. While credit conditions tighten when the yield curve inverts, there is considerable lag and the chart below shows that credit growth remains high while the yield curve is inverted.

Yield Curve Inversions & Bank Credit

A far more imminent warning (of recession) is when the yield differential recovers above zero.

Why does a recovering yield curve warn of impending recession?

First, you need to understand what causes the yield curve to invert. Economic prospects weaken to the extent that bond investors are prepared to accept lower long-term yields than the current short-term yield, in anticipation that interest rates will fall. The inverted yield curve will continue for as long as rates are expected to fall but will rapidly recover when the Fed starts to cut rates.

Treasury Yields

Falling short-term yields flag that the Fed is cutting interest rates, confirming bond investors earlier suspicions of a weakening economy. That serves as a reliable warning, after an inverted yield curve, of impending recession.

We are not there yet. The Fed may have eased off on further rate rises but is still some way off from cutting rates.
