However, one problem of particular importance – at least in places like Europe and the Americas – is a rapidly aging population. As the population shifts grayer, potential consequences include higher dependency ratios, rising healthcare costs, and shifting economies and cities.
Europe: A Prime Example
We’ve discussed Germany’s demographic cliff before, but it’s not only Germany that will be impacted by a rapidly aging population.
The above animation from data visualization expert Aron Strandberg shows the median age of European countries between 1960 and 2060. Starting about a decade from now, you can see that the U.N. projects some European countries to start hitting a median age of 50 or higher. This includes countries like Spain, Italy, Portugal, and Greece, and then later Germany, Poland, Bosnia, and Croatia. The UK, France, Ireland, Scandinavia, and former Soviet countries will be younger – but only slightly so. Median ages in these places by 2060 will be in the early to mid-forties.
The Americas
Populations in North and South America are also graying fast, though not quite at Europe’s pace. Here’s a similar map of the Americas that highlights median age between 1960 and 2060, based on U.N. projections.
Chile and Brazil, in particular, are trending older. Meanwhile, Canada is not far behind with an expected median age of 45 in 2060. Interestingly, the United States is anticipated to only hit a median age of 42 by 2060, which is lower than almost all Western countries. While this makes the U.S. look younger in comparison, the country will still experience the same type of economic burden from an aging population. In fact, it’s expected that the population of Americans older than 65 years will nearly double from 48 million to 88 million over the coming three decades.
on Last year, stock and bond returns tumbled after the Federal Reserve hiked interest rates at the fastest speed in 40 years. It was the first time in decades that both asset classes posted negative annual investment returns in tandem. Over four decades, this has happened 2.4% of the time across any 12-month rolling period. To look at how various stock and bond asset allocations have performed over history—and their broader correlations—the above graphic charts their best, worst, and average returns, using data from Vanguard.
How Has Asset Allocation Impacted Returns?
Based on data between 1926 and 2019, the table below looks at the spectrum of market returns of different asset allocations:
We can see that a portfolio made entirely of stocks returned 10.3% on average, the highest across all asset allocations. Of course, this came with wider return variance, hitting an annual low of -43% and a high of 54%.
A traditional 60/40 portfolio—which has lost its luster in recent years as low interest rates have led to lower bond returns—saw an average historical return of 8.8%. As interest rates have climbed in recent years, this may widen its appeal once again as bond returns may rise.
Meanwhile, a 100% bond portfolio averaged 5.3% in annual returns over the period. Bonds typically serve as a hedge against portfolio losses thanks to their typically negative historical correlation to stocks.
A Closer Look at Historical Correlations
To understand how 2022 was an outlier in terms of asset correlations we can look at the graphic below:
The last time stocks and bonds moved together in a negative direction was in 1969. At the time, inflation was accelerating and the Fed was hiking interest rates to cool rising costs. In fact, historically, when inflation surges, stocks and bonds have often moved in similar directions. Underscoring this divergence is real interest rate volatility. When real interest rates are a driving force in the market, as we have seen in the last year, it hurts both stock and bond returns. This is because higher interest rates can reduce the future cash flows of these investments. Adding another layer is the level of risk appetite among investors. When the economic outlook is uncertain and interest rate volatility is high, investors are more likely to take risk off their portfolios and demand higher returns for taking on higher risk. This can push down equity and bond prices. On the other hand, if the economic outlook is positive, investors may be willing to take on more risk, in turn potentially boosting equity prices.
Current Investment Returns in Context
Today, financial markets are seeing sharp swings as the ripple effects of higher interest rates are sinking in. For investors, historical data provides insight on long-term asset allocation trends. Over the last century, cycles of high interest rates have come and gone. Both equity and bond investment returns have been resilient for investors who stay the course.
