How Overvalued is the Euro?

Robin Brooks Robin Brooks Substack

Date Posted:: June 22, 2026

Brooks argues the US and China are successfully “muscling their currencies down,” which in turn has led to “massive” Euro overvaluation. He expects the dollar to weaken vis-à-vis the Euro in H2.

We’re in a beggar-thy-neighbor world where the US and China are successfully muscling their currencies down. This means the [Euro] has to appreciate by default, so Euro overvaluation is going to get worse before it gets better. The blue line in the top left chart is EUR/$. The black line is the differential of 2y2y forward interest rates in the Euro zone versus the US. I like using 2y2y forward rates because they’re a proxy for where terminal rates will be in any hiking or easing cycle. The striking thing about this chart is that EUR/$ moved very closely with the rate differential in all of 2024 and in early 2025, but then decoupled after the rollout of reciprocal tariffs on April 2. EUR/$ has been trading at a premium relative to the 2y2y forward differential ever since. The top right chart looks at whether there’s a similar decoupling for GBP/$. There is, but it’s much less noticeable. There’s no decoupling of this sort for AUD/$ in the bottom left chart and also nothing comparable going on for $/CAD in the bottom right chart.

EUR/USD tracked the Eurozone–US 2y2y forward rate differential closely through 2024 and early 2025 but decoupled after the April 2 rollout of reciprocal tariffs, trading at a premium to that differential ever since.
With the US and China muscling their currencies down, the euro appreciates by default, so euro overvaluation is likely to worsen before it improves.
GBP/USD shows a similar but much less noticeable decoupling from rate differentials, while AUD/USD and USD/CAD show no comparable decoupling.

Demand-Driven Inflation

Domenico Giannone and Giorgio Primiceri Bookings Papers on Economic Activity

Date Posted:: October 1, 2026
Is Database:: Database

Giannone and Primiceri revisit the relative role of supply vs. demand shocks in generating the post-Covid inflation. Because aggregate demand curves estimated from pre-pandemic data are flat, supply shocks alone would not have generated large inflation in the absence of added demand stimulus.

Demand and supply curve slopes are estimated from pre-pandemic data using the essentially definitional restriction that supply shocks move prices and output in opposite directions along demand curves, while demand shocks move them together along supply curves; the plotted slopes represent Bayesian posterior medians rather than uniquely identified estimates. The estimated demand curves are relatively flat in both the US and euro area [Figure 7], reflecting the central banks’ strong pre-pandemic responses to inflation. With those slopes, adverse supply shifts cause large output losses but comparatively little inflation. [To successfully explain] the combination of inflation and output observed in 2022 therefore requires demand to shift outwards too. Strong demand, including unusually accommodative monetary policy [on top of strong fiscal expansion], cushioned the output losses while increasing inflation [Figure 7]. In 2021–22, both inflation and GDP as subsequently revised exceeded forecasts in the US and euro area. That combination is suggestive of unexpectedly strong demand, whereas an adverse supply surprise alone would raise inflation but lower output. [Figure 9].

The Bond Market Reckoning Has Only Begun

John Authers Bloomberg

The spread between 10-year French OATs and German Bunds has widened at a pace seen only during the eurozone sovereign-debt crisis. John Authers warns that France “satisfies all the classic conditions for a major debt crisis.”

Only in the worst days of the euro zone’s sovereign debt crisis, in 2011 and 2012, has the [spread of 10-Year French OATS over German Bunds] risen so fast. Talk of a second euro-zone crisis, this time with an epicenter in Paris, is growing, and it’s easy to see why. Why is this more of a problem for France and the UK? Beyond their deficits, they also shoulder much higher tax burdens than the US. Tax revenues are 25.2% of GDP in the US, the lowest of the major developed economies - but 35.3% in the UK and 43.9% in France. It’s hard to imagine after decades of tax-cutting, but a US politician could deal with the deficit fairly easily with a tax hike. It’s not clear that option is open to French lawmakers, even if they could somehow persuade voters to go along with them. The populist politicians of left and right, who currently look well placed in next year’s presidential elections, are in any case unlikely to try.

Tax revenues equal 25.2% of GDP in the US, the lowest among major developed economies, versus 35.3% in the UK and 43.9% in France, leaving American politicians more room to close the deficit with a tax hike.

Is The World Really Drowning In Debt?

Martin Wolf Financial Times

Date Posted:: September 30, 2026
Is Database:: Database

Wolf notes that the global debt-to-GDP ratio rose by less than 10pp btw 2018 and June 2026: after peaking at 337% in early 2021, it fell by 27pp by the end of 2023, as inflation boosted nominal GDP and eroded the value of existing debt.

The IIF shows that between 2018 and June 2026, the rise in the ratio of global debt to output was less than 10 percentage points. The story is striking: the ratio reached a post-Covid peak of 337% in early 2021, before falling by 27 percentage points by the end of 2023. What was this magical “debt-buster”? Good old-fashioned (and supposedly “unexpected”) inflation. This is — to put it mildly — not the first time inflation has wiped out debt. It was, to take one of countless examples, an important part of the UK’s elimination of its post-second-world-war debt. For countries able to print the money in which their debt is denominated, that is often what happens.

Foreign Capital Flows Into US Stocks Hit Record As Appetite For Debt Fades

Michael Taffe and George Steer Financial Times

Date Posted:: September 28, 2026
Is Database:: Database

Foreign investors bought a record net $426B of US equities and fund shares in Q2, up 62% y/y, part of a record $942B in the 12 months through July. Overseas investors bought a net $188B of US debt securities in Q2, down from $314B in Q1.

Foreign investors made a record $942bn in net purchases of US equities and investment fund shares in the 12 months to July, accelerating a shift in overseas investment towards American stocks and away from debt. The flows represented the highest rolling 12-month total in Treasury data going back to 1985. Net purchases of US equities and investment fund shares by foreign investors jumped to $426bn in the second quarter, up 62% from the same period in 2025, and surpassing the previous quarterly record of $299bn in 2022, according to the Bureau of Economic Analysis. Foreign demand for US debt moved in the opposite direction. Overseas investors bought a net $188bn of US debt securities in the second quarter, down from $314bn in the first.

De-reservification, Not De-dollarization

Brad Setser and Alex Etra Council on Foreign Relations

Date Posted:: September 16, 2026
Is Database:: Database

The stock of global dollar reserves has been roughly stable over the past decade. The world is not moving away from the dollar: dollar assets are shifting from official holdings of Treasurys towards private and quasi-sovereign holdings of risk assets.

Most of the current flow into the US from the “official” sector is coming from investors who are not classic reserve managers. Those flows remain heavily tilted toward the dollar, at least for now. Any real de-dollarization would likely occur first among these investors. Put differently, the dollar’s global role is increasingly as a source of returns, not a source of safety. The foreign bid, private and public, is for risk, not for Treasuries. It is currently fashionable in some circles to point to the diminution of the “convenience yield” on Treasuries even while the U.S. dollar continues to enjoy such a privilege. But the shift in the global investor base and their apparent portfolio preference for U.S. risk assets in lieu of Treasuries may help explain the divergence between the convenience yield on Treasuries and the convenience yield on the USD.

Rules Of Relevance

Jason Thomas Carlyle

Date Posted:: September 16, 2026
Is Database:: Database

US cumulative foreign borrowing since 2000 has reached 118% of GDP, but the US has earned more on foreign assets than foreigners earned on US liabilities. Carlyle speculates that this “exorbitant privilege” could erode if globalization unwinds.

The size of the implicit US borrowing subsidy rose with global trade volumes. The growth in trade during the period of “globalization” was driven by the rise of globally-interconnected production networks, with production processes sliced into stages and distributed across borders. Businesses at each stage of the process would both invoice and get invoiced in dollars. This [plausibly] boosted demand for Treasuries to meet dollar payment obligations and backstop foreign banking systems, which placed downward pressure on Treasury yields and cheapened broader dollar funding costs.

Takeaways by Macro Roundup^® AI

Cumulative US borrowing from the rest of the world has reached 118% of GDP since 2000, as domestic savings consistently fell short of domestic investment, with effective US net borrowing costs below zero until recently.
The implicit US borrowing subsidy grew with global trade volumes, as foreign demand for Treasuries to meet dollar payment obligations and backstop foreign banking systems pressed Treasury yields down and cheapened broader dollar funding costs.
Policies that scale back US external commitments, narrow the goods trade deficit, and restrict foreign adversaries’ access to dollar clearing further reduce the foreign savings available and willing to be recycled into low-yielding US assets.

Brooks argues the US and China are successfully “muscling their currencies down,” which in turn has led to “massive” Euro overvaluation. He expects the dollar to weaken vis-à-vis the Euro in H2.
