Global Leading Indicators, September 2025 - Tariffs, what tariffs?

The September 2025 edition of the global LEI chartbook can be found here. Additional details on the methodology are available here.

One point on the methodology that I may not have made entirely clear: the aggregate LEI diffusion referred to below—and shown in the first charts of the chartbook—is not the same as a standard diffusion index. It is calculated as the sum of two figures: the number of LEIs that are high and rising minus those that are high and falling, and the number of LEIs that are low and rising minus those that are low and falling. This approach is designed to provide a more accurate turning point signal than a simple diffusion index. For the September 2025 edition specifically, the value for the G20 LEI, shown on page three of the chartbook, has been extrapolated to reflect a small rise. This mirrors the increase in the G7 indicator, as the G20 value had not yet been updated when the data was pulled from the OECD.

I seem to have a knack for releasing these chartbooks just as markets are hit with a curveball. The August edition came out in the wake of the soft August payrolls report, which opened the door to a dovish shift by the Federal Reserve and rattled investor sentiment with renewed concerns about a potential slowdown—or even a recession—in the U.S. economy.

The siren song of dollar weakness

A weaker dollar seems to be the answer to everyone’s prayers at the moment—or more specifically, investors want exposure to the exceptionalism of U.S. capital markets without the currency exposure that comes with it. From the BIS, via FXStreet:

Many investors still want to remain invested in US equities (belief in US exceptionalism is alive and well!), but at the same time, they see growing risks for the US dollar, not least due to the US government’s attacks on the Federal Reserve. A significant depreciation of the dollar could reduce the returns on the actual equity investment or even wipe them out entirely. So what is the solution? Hedging against dollar weakness. Ultimately, these hedges are effectively bets on a weaker US currency and, if widely adopted, create selling pressure on the dollar."

Global Leading Indicators, August 2025 - Who's afraid of payrolls anyway?

Global leading indicators remained robust heading into autumn, despite softening compared to levels at the start of the year. Uncertainty always lurks in financial markets, and currently, (at least) three major questions are weighing on investors—threatening the ongoing optimism in the global economy and financial markets:

U.S. Trade Policy and Tariffs: Did the White House, back in April, effectively throw a boomerang that's now returning to hit both the U.S. and global economy in the face?
Sustainability of the AI Investment Boom: Is the surge in tech and AI-exposed equities evidence of a genuine transformation, a bubble that is about to pop with predictably adverse consequences for markets and the economy.
Global Bond Market Sell-Off: Investors are raising questions about long-term fiscal sustainability in the U.S., U.K., France, and Japan, even speculating about the erosion of monetary policy independence in the U.S. A crisis of confidence in one or more of these large bond markets could trigger turbulence across opaque, illiquid private credit markets, spilling over into the real economy.

AS Global Debt Chartbook, Q4-2024 - How long is a piece of string?

I’ve been sitting on this project for a while, but I’m finally ready to bring it above the fold. I’ve long wanted a straightforward overview of global debt levels—both public and private—and an easy way to compare them across countries, alongside their respective external dynamics. This is essential material for macro investors and researchers, yet it’s rare to find all the relevant information compiled in one place. The AS global debt chartbook is a first attempt at this. Like the LEI Chartbook, this project runs on Python code generated and compiled with the help of my trusty OpenAI assistant, with a few manual adjustments along the way. At the moment, it draws data from an Excel spreadsheet, but integrating APIs should be relatively straightforward down the line.
