Podcast Episode Notes: Thoughts on the Market - Oil Rally Tests Diversification Strategy
Overview In this episode of "Thoughts on the Market," Chief Cross-Asset Strategist Serena Tang discusses the implications of rising oil prices and geopolitical tensions on portfolio diversification strategies. She elaborates on how these factors could potentially alter the traditional relationship between stocks and bonds.
Key Details
- Host: Serena Tang, Chief Cross-Asset Strategist at Morgan Stanley
- Date: March 10, 2023
- Main Topic: Impact of rising oil prices on stock-bond correlations and diversification strategies
Background
- For decades, investors have relied on the principle that stocks and bonds generally move in opposite directions.
- During the period from 2021 to 2023, both stocks and bonds sold off concurrently, leading to significant losses in traditional portfolios (notably the 60/40 equity-bond allocation).
Key Concepts
Traditional Stock-Bond Relationship
- Negative Correlation: Traditionally, when equities decline, bond prices tend to rise, helping to mitigate losses in a diversified portfolio.
- Recent Trends: Following the pandemic, both asset classes experienced declines simultaneously due to concerns over rising inflation in bonds and slowing growth in equities.
Oil Price Dynamics
- Geopolitical Concerns: Rising oil prices are influenced by tensions in regions like the Strait of Hormuz.
- Stagflation Risk: Higher oil prices can simultaneously increase inflation and dampen economic activity, leading to stagflation.
- Market Implications: If markets start to anticipate stagflation, the negative correlation between stocks and bonds could weaken, causing both to move in the same direction.
Current Market Analysis
- Despite recent volatility, the correlation between stocks and bonds remains predominantly negative, allowing for some level of diversification.
- Treasury Correlations:
- Short-Term Bonds: U.S. 2-year Treasuries have maintained a strong negative correlation with equities.
- Long-Term Bonds: 30-year Treasuries show a stickier correlation, partly due to perceptions of greater risk.
Financial Indicators
- Bear Flattening: A situation where short-term interest rates rise faster than long-term rates, indicating heightened inflation risks.
- Investor Considerations: As oil prices rise, investors must consider whether inflation or slow growth will dominate market conditions, influencing asset performance.
Critical Takeaways
- Evolving Diversification: While diversification through bonds is not disappearing, it is becoming more complex, and the focus should shift to understanding which bonds provide effective diversification.
- Investment Strategy: Investors may need to reassess their portfolio strategies in light of changing correlations and economic indicators.
Conclusion
- Rising oil prices and geopolitical uncertainties could challenge traditional diversification strategies, making it crucial for investors to evaluate the specific types of bonds in their portfolios.
- The evolving market landscape necessitates a nuanced approach to asset allocation, focusing on risk management and understanding the dynamics of different bond maturities.

Today, what happens if your main diversification strategy suddenly stops working because of oil price moves? It's Tuesday, March 10th at 10 a.m. in New York. For decades, investors have relied on the idea that stocks and bonds return tend to move in opposite directions. When equities fall, bond prices often rise, helping cushion portfolio losses. But that relationship isn't guaranteed. Between 2021 and 2023, coming out of a pandemic, stocks and bonds sold off together. And the traditional 60-40 equity bond portfolio suffered its worst annual performance in nearly a century.
0:51Now, recent geopolitical tensions and rising oil prices are raising a familiar concern for investors. Could that uncertainty dynamic return? At first glance, oil prices may seem like a narrow commodity story. But in reality, they can shape the entire macroeconomic environment. The classic negative correlation between stocks and bonds depends on a fairly simple economic pattern. Growth and inflation moving in the same direction. When economic growth accelerates, inflation often rises as well. In that environment, equities may perform well while bonds weaken. But when growth and inflation move in opposite directions, the relationship between stocks and bonds can flip.
1:42That's what happened coming out of the pandemic. Bond investors were worried about rising inflation, while equity investors were worried about slowing growth. In that scenario, both asset classes' returns declined at the same time. A sustained oil price shock could potentially recreate those conditions. Higher oil prices can push up inflation, while also weighing on economic activity, a combination that economists often refer to as stagflation. If markets begin to price in that kind of environment again, the relationship between stocks and bonds could shift back towards that less favorable regime.
2:27Despite recent volatility tied to tensions in the Middle East, the relationship between stocks and bonds today still largely reflects the traditional pattern. Overall, stock bond returns correlation remain negative, meaning bonds can still help diversify equity risk. In fact, correlations between U.S. stocks and two-year Treasury returns have been trending negative since 2024. And on a longer term basis, they are now extremely negative relative to the past three years. But the key point here is that not all bonds behave the same way. Many investors think of government bonds as a single asset class, but the maturity of the bond, how long it takes to repay, matters a lot for diversification.
3:19Shorter dated bonds, such as two-year U.S. Treasuries, have maintained stronger negative correlations with equities. Longer dated bonds, however, particularly the 30-year Treasury, have behaved a bit differently. The correlation with stocks has been stickier and less negative, partly because markets increasingly view longer-dated bonds as risky. As a result, the difference between how two-year and 30-year treasuries move relative to stocks has remained unusually wide for several years. In recent days, oil prices have been rising, linked in part to the concerns around the Strait of Hormuz. That's pushing up yields at the front end of the Treasury curve, creating what's known as bear flattening.
4:08In other words, short-term interest rates are rising faster than long-term ones, reflecting markets placing more emphasis on inflation risks. And that brings us to the key questions for investors. Which risks will dominate for me here? Is it going to be higher inflation or slower growth? The answer could determine which assets provide better diversifications in the months ahead. So the takeaway is this. Higher oil prices and geopolitical risks could increase the chances that stocks and bonds move together again. But diversification isn't disappearing. It's just becoming more nuanced. For investors, the real question isn't whether bonds diversify portfolios.

Welcome to Thoughts on the Market. I’m Serena Tang, Morgan Stanley’s Chief Cross-Asset Strategist.
Today: what happens if your main diversification strategy suddenly stops working because of oil price moves?
It’s Tuesday, March 10th, at 10am in New York.
For decades, investors have relied on the idea that stocks and bonds return tend to move in opposite directions. When equities fall, bonds often rise, helping cushion portfolio losses. But that relationship isn’t guaranteed. Between 2021 and 2023, coming out of the pandemic, stocks and bonds sold off together, and the traditional 60/40 equity-bond portfolio suffered its worst annual performance in nearly a century.
Now, recent geopolitical tensions and rising oil prices are raising a familiar concern for investors: Could that uncertainty dynamic return? At first glance, oil prices may seem like a narrow commodity story. But in reality, they can shape the entire macroeconomic environment.
The classic negative correlation between stocks and bonds depends on a fairly simple economic pattern: growth and inflation moving in the same direction. When economic growth accelerates, inflation often rises as well. In that environment, equities may perform well while bonds weaken. But when growth and inflation move in opposite directions, the relationship between stocks and bonds can flip. That’s what happened coming out of the pandemic. Bond investors worried about rising inflation, while equity investors were worried about slowing growth. In that scenario, both asset classes' returns declined at the same time.
A sustained oil price shock could potentially recreate those conditions. Higher oil prices can push up inflation while also weighing on economic activity – a combination that economists often refer to as stagflation. If markets begin to price in that kind of environment again, the relationship between stocks and bonds could shift back toward that less favorable regime.
Despite recent volatility tied to tensions in the Middle East, the relationship between stocks and bonds today still largely reflects the traditional pattern. Overall, stock-bond returns correlation remains negative, meaning bonds can still help diversify equity risk. In fact, correlations between U.S. stocks and 2-year Treasury returns have been trending negative since 2024, and on a longer-term basis they are now extremely negative relative to the past three years. But the key point here is that not all bonds behave the same way.
Many investors think of government bonds as a single asset class. But the maturity of the bond – how long it takes to repay – matters a lot for diversification. Shorter-dated bonds, such as 2-year U.S. Treasuries, have maintained stronger negative correlations with equities. Longer-dated bonds, however – particularly the 30-year Treasury – have behaved a bit differently. Their correlation with stocks has been stickier and less negative, partly because markets increasingly view longer-dated bonds as risky. As a result, the difference between how 2-year and 30-year Treasuries move relative to stocks has remained unusually wide for several years.
In recent days oil prices have been rising -- linked in part to concerns around the Strait of Hormuz. That’s pushing up yields at the front end of the Treasury curve, creating what’s known as a bear-flattening. In other words, short-term interest rates are rising faster than long-term ones, reflecting markets placing more emphasis on inflation risks. And that brings us to the key questions for investors: Which risks will dominate from here – is it going to be higher inflation or slower growth? The answer could determine which assets provide better diversifications in the months ahead.
So the takeaway is this: Higher oil prices and geopolitical risks could increase the chances that stocks and bonds move together again. But diversification isn’t disappearing. It’s just becoming more nuanced. For investors, the real question isn’t whether bonds diversify portfolios. It’s which bonds do.
