In brief
- Economic forecasting is challenging, but understanding the capital cycle can help.
- Led by investment in AI, the US has embarked on a new capital cycle.
- The result is a shifting landscape of likely industry winners and losers.
While equity market forecasters are wrong about half the time, they tend to have a higher success rate than economists, who predicted a US recession in 2024 and inflation falling back to 2%. More recently, the latest US labor report showed that the number of new jobs created in December blew past consensus forecasts by more than 3 standard deviations.
Why is economic modeling so hard?
Economic forecasting warrants a stronger adjective than hard. Its exceptionally challenging and complex. While several factors are at play, at its core, gross domestic product isn’t a static measure like wealth, enterprise value or stock market capitalization. Instead, GDP captures the dynamic flow of capital within an economy, meticulously tracking expenditures — their magnitude, location and source — and comprises many variables moving in conflicting directions.
As a result, the aggregated data streams used in economic modeling can sometimes make a change in trend or direction hard to see. Seemingly small or immaterial data points are often underemphasized if not overlooked. Often the most critical datapoints, such those that mark the end or beginning of meaningful directional changes in the flow of capital, reveal themselves years later as important inflection points.
This is where a bottom-up approach may complement a top-down forecast.
Getting at the economic cycle through the capital cycle
The purpose of capital markets is to bring together society’s savers, those seeking returns above cash yields and those with ideas but in need of funds. In exchange for capital, entrepreneurs are willing to give up some of the potential spoils. Since capital is allocated in accordance with the potential utility and risk of the project, where capital is being allocated to and from signals where the private market sees growth and contraction.
For example, we can observe this in the very long but weak business cycle following the 2008 financial crisis. Households and banks undertook balance sheet repair that warranted years of austerity and deleveraging that deflated economic growth. With anemic revenue growth, developed market companies only added to the malaise by offshoring, which lowered spending and expenses. With deflation risks mounting, central banks rekindled a capital cycle by artificially suppressing borrowing costs. While a new capital cycle was borne, it wasn’t the one many had hoped for, fueled by tangible fixed investment. Instead, newly created capital was cycled to shareholders via dividends and stock buybacks, culminating in one of the longest economic cycles in decades, one that produced immense wealth for many equity owners.
So where is capital flowing today and does the answer to that question explain the current state of US economic exceptionalism? More important, can it give us insight into the future?
The capital cycle now and why it matters
A lot of goods consumed in the US, including many related to national security, are manufactured outside the country. As a result, companies haven’t had to create tangible capital because China has done it for them to the benefit of shareholders.
However, in recent years, the combination of COVID, rising geopolitical tensions and prospects for future tariffs has brought about a shift. An efficient, low-cost system is being exchanged for one where products are produced more simply and closer to home. Following many years of US corporate capital expenditures falling relative to sales, today it’s reversing. A new capital cycle has emerged, but this is only part of the narrative.
Since the US is the primary home of artificial intelligence, it’s sucking up the world’s investment capacity. The exhibit below illustrates the net level of US international investment (the difference between US residents’ investments abroad and foreign investment in the US). At -$22 trillion, it’s more than quadrupled since the runup to the global financial crisis.
