The question

In 2024, French corporations — financial and non-financial — invested 12.3% of gross domestic product (GDP) in gross fixed capital formation (GFCF), that is in machinery, buildings, software and durable equipment, according to the national accounts disseminated by Eurostat. That is a level close to the series' maximum, 12.7% in 2022, and above anything seen since 1949 outside the last three years.

This record came while the cost of money tripled: the State's ten-year rate went from 0.01% in 2021 to 3.37% in 2025, and the rate on new loans to businesses from 1.30% to 4.61% in 2024. The question is therefore: what finances this investment, if not cheap credit? Margins, savings, taxation — or all three?

What the data show

Over seventy-five years, corporate investment as a share of GDP oscillates within a narrow band: 9.3% at the low in 1954, 12.7% at the high in 2022, 10.8% on average between 1990 and 2019. That is the series' first lesson: the ratio is remarkably stable, and two points of GDP separate a decade of weak investment from a decade of strong investment.

Two recessions show what a crisis does: between 1992 and 1994, the ratio loses 1.3 points of percentage; between 2008 and 2009, 1.2 points in one year. Conversely, the 2022-2024 rate rise cost only 0.4 point between 2022 and 2024: a dip, not a break.

The margin rate of non-financial corporations, published by the Institut national de la statistique et des études économiques (INSEE) — the share of value added left to the firm once wages and contributions are paid — was 30.7% in 2019, reached 33.5% in 2021, the highest since the series began in 1949, and stands at 32.2% in 2025. On average it stood at 32.4% over 2021-2025 against 30.7% over 2010-2019.

  • Corporate investment, % of GDP

What to see

  • A band of nine to thirteen per cent over the whole period: the ratio moves little.
  • Three clear troughs, 1954, 1993-1997 and 2009, and a peak in 2021-2023.

What this does not mean

  • A stable share of GDP is not a stable amount: GDP has multiplied several times in volume.

What has changed

What has changed since 2021 is the price of credit and the level of margins, in opposite directions. The rate on new loans to non-financial corporations, compiled by the Banque de France for the European Central Bank (ECB), went from 1.30% in 2021 to 4.35% in 2023 and 4.61% in 2024, before easing to 3.63% in 2025 (3.61% in July 2026). Meanwhile, the margin rate stayed above thirty-two per cent every year except 2022.

The ratio's lesson lies there: firms invested at a record level because they had record margins to do so, which reduced their dependence on credit precisely when it was becoming dearer. That is not a proven causality — it is a coincidence of levels that the mechanism of self-financing makes consistent.

The visible relationships

What cannot be claimed

The aggregate ratio mixes large firms, which finance themselves on markets, and small ones, which depend on bank credit: this page cannot say whether rising rates held back the latter while the former invested. The breakdown by size is not served.

Nor does it say what was invested in: machinery, software, buildings, energy transition, compliance. High investment that does not raise productivity — the finding of the neighbouring analysis — calls for that decomposition, which is missing here.

Finally, the presentation contains no investment advice: saying where household savings “should” go is not France ÉcoScan's purpose.

The events that shed light on the path

Where we stand today

In 2025, the margin rate is 32.2%, business credit at 3.63% on annual average (3.61% in July 2026), growth at 0.8%. Investment for 2025 is not yet published; that of 2024, 12.3% of GDP, remains above any vintage before 2021.

What the reader can take away

Margins finance French business investment, over the long run and even more since 2021: when they are high, investment follows with a lag, and credit becomes a complement whose price matters less. The rate rise was absorbed because it coincided with record margins — not because credit does not matter.

What the reader can keep: abundant household savings and high business investment are two true facts that do not explain each other. An account gives access to the full cross-reading: margins and investment over seventy-five years, interest rates, savings, taxation, and the episodes that tested each channel.
