On the subject of bonds, here are two interesting econ ideas about how the changing negative/positive correlation between stocks and bonds could affect the risk premium for bonds.
https://www.marketwatch.com/story/this-researcher-came-up-with-a-key-insight-for-why-bonds-sell-off-six-years-ago-people-thought-it-was-a-strange-topic-d25cff9c?mod=home-pageIn a nutshell, and according to my understanding:
1) Stocks and bonds are sometimes negatively correlated and sometimes positively correlated. I.e. sometimes a bond portfolio moves opposite a stock portfolio, hedging the risks from stocks, and other times bonds move alongside stocks, adding to the overall risk exposure.
2)
"When the bond and stock markets move in different directions, bonds are a good hedge for stocks, making it easier for markets to soak up new Treasury supply, wrote Hou in the research paper. But when the correlation is positive — when stocks and bonds move in the same direction — bond risk premiums rise in response to an increase in the Treasury supply.
“Investors will need to be compensated for taking on additional risk that accompanies the increase in supply. Demand will be less elastic and risk premiums will need to rise more per unit of supply,” he wrote."That is to say, when investors face an environment where stocks and bonds are moving together, they have to worry about their stocks and bonds falling together, like in 2022. Bonds become less useful if they cannot hedge a portfolio, and so demand for them drops. In a correlated environment, cash becomes the only hedge.
3) Investors require more compensation for an asset correlated to stocks and so that reduces demand and bond prices further than would otherwise be logical. I.e. when it's 2022 and you're losing big money on both stocks and bonds amid a rate-hiking campaign, you don't have as much to reallocate to new bonds. At other times, when stocks and bonds are counter-correlated, you are making money on rising stocks and so you have the funds to buy falling bonds, or vice versa. When both assets are correlated, the only way to hedge is cash, and so instead of a 60% stock 40% bond portfolio maybe you choose a 60% stock 40% cash portfolio. That means selling bonds. This is what Hu means when he says "demand will become less elastic and risk premiums will need to rise more per unit of supply."
-----------------
The 10 year rolling correlation between stocks and bonds switched from positive to negative around 1999, and then they probably switched from negative to positive in 2022. It is
thought by some this switch occurs when markets switch from a high-growth regime where the concern is inflation to a low-growth regime where the concern is growth.
-----------------
During the 20-teens and after the pandemic, the market was concerned with growth. Investors were interested in bonds because they were skeptical growth would continue and stocks would do well. Starting in 2022 amid rapid economic growth, investors suddenly switched to being concerned about inflation. If rates were going to rise, neither stocks nor bonds would do well, so both sold off.
Money market account inflows became huge in 2023. That's because cash was the only thing working as a hedge.
It's fair to say we're currently in an environment of rapid growth where investors' main concern is inflation. However, concerns about a possible recession may soon move to the forefront, bringing back concerns about growth. The FFR is 5.5%, and likely to go to 5.75% depending on September's CPI and PCE. After a decade-plus of corporate malinvestment in low-yielding assets ranging from treasuries to mortgages to physical corporate assets, everyone is about to face a 6-7% cost of refinancing debt on assets that return 3-5%. That means deleveraging and shutting down under-performing businesses - and growth anxiety for stocks.
Thus I expect a more typical negative stock-bond correlation in 2024 - the reversal of 2022. Bad news for stocks will be good news for bonds going forward, and vice versa. If rate cuts come and boost bond prices, it will be due to the sort of issues that drive stock prices down - a recession or economic crisis. On the flipside, more growth will boost stocks and cause interest rates to rise more, depressing bonds.
Bonds make more sense as hedges or as low-risk bear market bets with big upside now than they did in 2022. In the event of a reversal in interest rates, the longest-duration bonds - which lost the most over the past 1.75 years - will have the highest payoff due to the same reason that devastated them when rates rose:
convexity.
For example, a 30y treasury issued in May 2020 (CUSIP: 912810SN9) with a 1.25% coupon is today selling for $452.40. If rates fell from today's 4.99% to 4% in one year, that bond would gain about 23.8% in value.
If rates fell to 3%, it would gain about 51.3%%.
If rates fell to 2%, it would gain about 86%.
On the flipside, if long-duration rates continue to rise, your possible losses are:
Six percent: about -15.2%
Seven percent: about -29%
Thus there is a lopsided payoff function, with significantly more to gain than there is to lose. This is the bond where you should go all-in if you are confidently forecasting a repeat of 2008, when the FFR was cut 500bp in about 18 mos. The downside is that the current yield of 2.765% is not very high. Those already living off their money may not have the stomach to endure this trade, which might take a couple of years to come to fruition.
