Secular drivers of the global real interest rate

Lukasz Rachel and Thomas Smith Bank of England

Global long-term real interest rates have decreased by 450bps over 30 years, driven by demographic forces, higher inequality, and reduced public investment. Central banks are more rate takers than makers.

Over the past 30 years, global long-term real interest rates have decreased by about 450 basis points, driven largely by demographic forces (90bps), higher inequality within countries (45bps), and a shift towards higher saving by emerging market governments post-Asian crisis (25bps). Despite stable global saving and investment ratios, desired investment levels have fallen due to a decline in the relative price of capital goods (50bps) and reduced public investment (20bps). The spread between the rate of return on capital and risk-free rates has widened, further lowering desired investment and risk-free rates by 70bps. These factors, combined with lower expectations for trend growth (100bps), account for 400bps of the decline, indicating that central banks are more rate takers than makers, as looser monetary policy is a consequence, not a cause, of falling long-term rates.

BofE working paper that will be presented @ Brookings in March, evidence central banks have limited control over long term interest rates

"....Long-term real interest rates across the world have fallen by about 450 basis points over the past 30 years. The co-movement in rates across both advanced and emerging economies suggests a common driver: the global neutral real rate may have fallen. In this paper we attempt to identify which secular trends could have driven such a fall. Although there is huge uncertainty, under plausible assumptionswe think we can account for around 400 basis points of the 450 basis points fall....Our analysis suggests the desired savings schedule has shifted out materially due todemographic forces (90bpsof the fall in real rates),higher inequality within countries (45bps)and a preference shift towards higher saving by emerging market governments following the Asian crisis (25bps).If this had been the whole story, we would have expected to see a steady rise in actual saving rates globally. But global saving and investment ratios have been remarkably stable over the past thirty years suggesting desired investment levels must have also fallen.We pin this decline in desired investment on a fall in the relative price of capital goods (accounting for 50bps of the fall in real rates) and a preference shift away from public investment projects (20bps). Also, we note that the rate of return on capital has not fallen by as much as risk free rates. The rising spread between these two rates has further reduced desired investment and risk free rates down (by 70bps). Together these effects can account for 300bps of the fall in global real rates....When combined, lower expectations for trend growth and shifts in desired savings and investment can account for about 400bps of the 450bps decline in the global long-term neutral rate since the 1980s...100bps explained by the deterioration in the outlook for trend growth....ever looser monetary policy is not the cause, but the consequence of the fall in long -term rates. .."

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

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.

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

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

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.

Global long-term real interest rates have decreased by 450bps over 30 years, driven by demographic forces, higher inequality, and reduced public investment. Central banks are more rate takers than makers.
