The Murder-Suicide of the Rentier: Population Aging and Risk Premium

Joseph Kopecky Working Paper

Date Posted:: July 22, 2020
Is Database:: Database

Aging households, notably baby boomers, contribute to a savings glut that depresses real interest rates on safe assets while holding lower equity shares, leading to a higher ERP.

Demographic shifts, particularly aging populations, are key drivers behind the decline in risk-free rates and the rise in equity risk premiums (ERP). Since 2000, the global ERP has increased by 2.5 percentage points, with similar trends in the US where the ERP rose by 2-5 percentage points from the late 1990s to 2015. Aging households, notably baby boomers, contribute to a savings glut that depresses real interest rates on safe assets while holding lower equity shares. This demographic shift reduces pressure on risky assets, leading to a higher ERP. Between 1990 and 2017, models account for significant portions of ERP fluctuations and predict a continued decline in risk-free rates to -278 bps by 2050, with the ERP stabilizing at 498 bps. As demographic forces persist, the expected return on equity is projected to fall to 220 bps, underscoring the impact of aging on asset demand dynamics.

New Alan Taylor suggests demographics are responsible for the rising ERP (he uses Damodaran’s EPR data as well):

“… global equity risk premium has risen by 2.5 percentage points since the year 2000. Similar trends can be observed in the United States, with an equity premium in 2015 that is between two and five percentage points higher than it was in the late 1990s (pre-tech bubble crisis)…..Aging households, the boomers, are responsible for a savings glut which has helped to drive down real interest rates on safe assets, but they have relatively lower shares of their portfolio in equity. As a result, the shifting population weight moving toward these households does not have the same effect on equity returns that it has been shown to have on risk free assets…Summing up, Figure 12 shows that between 1990 and 2017 our model can account for: roughly all of the fall and rise in the ERP “low” amplitude estimate (Damodaran); roughly half of the fall and rise in the ERP “mid” amplitude estimate (our estimate using the E/P ratio and 1-year yields); or roughly one third of the fall and rise in the ERP “high” amplitude estimate (Duarte and Rosa). Looking to the future, the model predicts a continued fall in the risk free rate to -278 bps by 2050 with the ERP roughly stable at 498 bps. The expected return to equity therefore continues to fall to just 220 bps as demographic shifts continue to relentlessly boost the demand for all assets, but especially safe assets….”

Joseph Kopecky and Alan Taylor, "The Murder-Suicide of the Rentier: Population Aging and Risk Premium," Working Paper June 2020, https://www.josephkopecky.com/Papers/KopeckyTaylor.pdf

More Taylor:“…Population aging has been linked to global declines in real interest rates. A similar trend is seen for equity risk premia, which are on the rise. An existing literature can explain part of the declining trend in safe rates using demographics, but has no mechanism to speak to trends in relative returns on different assets. We calibrate a heterogeneous agent life-cycle model with equity markets and aggregate risk,and we show that aging demographics can simultaneously account for both the majority of a downward trend in the risk free rate, while also increasing the return premium attached to risky assets. This is because the life-cycle savings dynamics that have been well documented exert less pressure on risky assets as older households shift away from risk. Under reasonable calibrations we find declines in the safe rate that are considerably larger than most existing estimates between the years 1990 and 2017. We are also able to account for most of the rise in the equity risk premium. Projecting forward to 2050 we show that persistent demographic forces will continue push the risk free rate further into negative territory, while the equity risk premium remains elevated….”

How To Buy A Trade Surplus

Joseph Gagnon and Nishtha Agrawal Peterson Institute For International Economics

Is Important:: Important

Using annual data for 146 countries from 1985 – 2024, Gagnon and Agrawal find that a $1 increase in a country’s cyclically adjusted fiscal deficit is associated with a 22–38¢ increase in its current-account deficit, with most of the estimates ~30¢.

Table 1 presents regression results. The evidence strongly suggests that governments can buy current account surpluses. Raising the fiscal balance by $1 tends to raise the current account by $0.30 [Table 1, first row]. Issuing $1 of domestic currency debt to buy foreign-currency assets (foreign exchange intervention) raises the current account anywhere from $0.20 to $1.00, with a value around $0.50 to $0.60 most plausible [Rows 2 though 5]. NOF is Net Official Flows, and NOS is the stock of net official foreign assets. The most powerful policy, as exemplified by Norway and Singapore, is to run a fiscal surplus and invest the proceeds in foreign-currency assets. In that case, $1 buys a current account surplus of around $0.80 or so. The results are supported by annual panel regressions of current accounts and cross-country stock regressions of cumulated current accounts or stocks of net foreign assets. The estimated effects in the panel regressions may be biased down slightly by incomplete modeling of lagged effects.

Honey, Who Shrunk the U.S. Income Surplus?

Matthew Higgins and Thomas Klitgaard Liberty Street Economics

Date Posted:: May 19, 2026
Is Database:: Database

The US net international investment position worsened by about $16tn between 2019 and 2025, driven by roughly $5.5tn in net inflows and $10tn in valuation losses, as higher rates hit a larger net liability stock, raising interest rate-sensitivity.

Foreign holdings of U.S. financial assets are immense, with official estimates putting their current market value at $69 trillion. U.S. holdings of foreign assets are also impressive but much smaller, at $41 trillion. The shortfall in U.S. foreign assets relative to foreign liabilities has been mounting for decades. Yet U.S. investment income receipts—in profits, dividends, and interest—comfortably exceeded income payments until recently. Payments on U.S. assets owned by foreign investors represent a servicing burden for the U.S. economy. Profits, dividends, and interest payments that would otherwise accrue to domestic investors instead flow abroad. Given the need to sell U.S. assets to finance ongoing trade deficits, this servicing burden seems likely to mount. The related buildup in the U.S. net liability position in interest-bearing assets will also make the income balance more sensitive to swings in interest rates. This increased sensitivity is already in evidence. At present, with the asset-liability gap at -$15 trillion, a 1 percentage point increase in U.S. and foreign interest rates would subtract $150 billion from the U.S. net income balance. (A 1pp fall in rates would result in a similar improvement.) Only five years ago, a 1 percentage point rise in rates would have subtracted $100 billion.

Takeaways by Macro Roundup^® AI

The $28tn gap between foreign holdings of U.S. assets ($69tn) and U.S. foreign holdings ($41tn) drives mounting income payments abroad.
A 1pp interest rate rise now subtracts $150bn from U.S. net income—50% more than five years ago—as the $15tn net.
Ongoing trade deficits force asset sales to foreign investors, leading to larger servicing burdens and greater exposure to interest rate.

Don't Blame America's Current Account Deficit On the Dollar

Maurice Obstfeld Peterson Institute for International Economics

Date Posted:: April 14, 2026
Is Database:: Database

Noting the minimal relationship between official liabilities and the CA, Obstfeld argues that the reserve currency role of the dollar is not the cause of the trade deficit. He urges reduction in the US fiscal deficit to increase national saving.

Critics of the dollar's global role have argued that foreign official dollar purchases (labeled US incurrence of official liabilities in the figure) feed one-for-one into US current account deficits. To illustrate the true loose relationship between these two variables, the figure shows both of them over the 2003–25 period, as percentages of GDP. US net incurrence of liabilities to official holders, reported with a minus sign as in standard balance-of-payments methodology, is usually far too small to mirror the US current account deficit. And since roughly 2014, net official financial inflows have fluctuated around zero as the current account deficit has widened. To be sure, the strong international demand for dollars may make the dollar stronger against foreign currencies than it would be otherwise, [but] while they imply a smaller current account balance, they do not necessarily imply a negative balance and certainly not a rising negative balance, especially when foreign dollar reserve holdings have been shrinking relative to global economic activity (as figure 1 also implies). The euro is the world's second reserve currency, yet the euro area has a current account surplus. Britain had surpluses up until World War I despite issuing the world's premier global currency and hosting its leading financial center. Reducing the US fiscal deficit materially and sustainably is the most important US policy prerequisite for global current account rebalancing.

Understanding Global Imbalances

Date Posted:: April 7, 2026
Is Database:: Database

As of 2024, the US, China, Germany, and Japan accounted for ~2/3 of total global imbalances (the sum of the absolute value of each economy’s current account deficit and surplus). The US CA deficit is between 0.8 and 1% of world GDP.

Four economies—the US, China, Germany, and Japan—account for roughly two-thirds of global imbalances. The US deficit—equivalent to 4% of GDP as of 2024—has been financed by capital inflows and portfolio investors seeking dollar assets. Germany and Japan’s surpluses have been driven by high saving rates, joined by substantial surpluses in China beginning in the 2000s. Oil-exporting countries’ surpluses fluctuate with commodity prices, creating episodic contributions to global imbalances. In earlier decades, surpluses and deficits were more cyclical: countries moved in and out of surplus depending on business cycles, commodity shocks, and exchange rate movements. While there is no standard definition of persistence, the average duration of a deficit or surplus spell roughly doubled since the 1980s. Persistent surpluses over the past two decades have accumulated into very large net foreign asset positions for economies such as China, Germany, and Japan, with each holding net foreign assets equivalent to 3–3.5% of global GDP in 2024. Similarly, persistent deficits have built up into large net liability positions, most notably in the US where the NIIP stands at about -25% of global GDP in 2024, underscoring the central role of the US position in global balances (Figure 6).

China’s Cheap Money Is Shaking $9.5 Trillion Global Loan Market

Bloomberg Staff Bloomberg

China’s savings glut and “monetary easing to counter slowing growth” are manifesting themselves in credit expansion overseas, as bankers seek higher yields than they can get at home amidst deflationary pressure.

Chinese banks, flush with low-cost funds, are reshaping parts of the global loan market, underscoring how deflationary pressures in the world’s second-largest economy are increasingly influencing competition with international lenders. Much like US and European manufacturers who have long complained about being undercut by cheaper Chinese rivals, bankers at global institutions now say they’re facing the financial equivalent: being priced out of some of Asia’s most sought-after borrowers as Chinese lenders extend cheaper credit across borders. Enabled by Beijing’s monetary easing to counter slowing growth, Chinese banks are expanding overseas lending amid weakening domestic credit demand. That edge may prove even more significant as the Iran crisis threatens to upend global energy markets, raising the likelihood that major central banks will hold off easing interest rates amid mounting uncertainty.

Tariffs and "International Payments Problems"

The worsening of the US net international investment position – from -20% of US GDP in 2010, to -53% pre-pandemic, and to -89% as of the end of 2025Q3 – reflects valuation gains on US stocks relative to stocks in the rest of the world.

Foreigners are accumulating more financial claims on Americans than Americans are accumulating on foreigners across every single category: FDI, stocks, bonds, physical currency, deposits, and loans. Foreign official investors supposedly have been mild sellers of U.S. assets over the past 12 months, but the standard measure does not include state-affiliated institutions that operate on behalf of foreign governments. Meanwhile, the U.S. net international investment position has swung massively over the past few years, from -20% of U.S. GDP in 2010, to -53% of U.S. GDP on the eve of the pandemic to -89% as of the end of 2025Q3. Almost all of that reflects massive valuation gains on U.S. stocks relative to stock markets in the rest of the world. The good news is that actual U.S. indebtedness has not meaningfully increased, and the methods used to assign market values to FDI in the U.S. and abroad make the situation look more extreme than it is. (U.S. FDI assets in Ireland are overwhelmingly big tech and big pharma, for example, but the market value of those assets is imputed based on the performance of the maker of Kerrygold.) The bad news is that, if the current level of the NIIP is unsustainable, the easiest way for it to revert is for U.S. stock prices to fall dramatically.

Aging households, notably baby boomers, contribute to a savings glut that depresses real interest rates on safe assets while holding lower equity shares, leading to a higher ERP.
