What France's Livret A really finances

France’s Livret A promises three simple things: savings available on demand, an interest rate set under public rules and tax-free interest. The other side of the account is far less visible. At the end of 2025, French Livrets A held €440 billion. Part of that money had entered a public balance sheet that finances housing over several decades and also held nearly €116 billion of French government debt. This arrangement does not turn each saver into the owner of a government bond. It collectively transforms liquid deposits into long-term loans and securities.

The €116 billion figure is striking, but it does not explain the Livret A on its own. The French system has two funding channels. A deposit account is different from a bond fund, and the government bonds in this public portfolio perform several jobs: they fund France, help protect the balance sheet against inflation and provide assets that can be sold when savers withdraw money.

For readers outside France, the Livret A is a tax-free, state-regulated savings account whose balance can be withdrawn on demand. The LDDS is another regulated account focused on sustainable and solidarity-based development. The means-tested LEP is designed for lower-income savers. The three products feed a shared financing architecture.

Ownership comes first

A Livret A holder does not own part of a social-housing building, a direct claim on a small company or a line of French government bonds. The holder has a claim on the bank that operates the account. The balance displayed in the banking app is that bank’s debt to its customer.

The deposits are then pooled. For the Livret A and LDDS, the standard centralisation rate is 59.5%. For the LEP, it is 50%. The centralised amounts become funding for the Fonds d’épargne, translated here as the Savings Fund, which is managed by the Caisse des Dépôts, France’s public long-term investment institution. The remainder stays on the banks’ balance sheets. Banque de France, legal framework for regulated savings

This structure makes it impossible to follow “your” euro. Deposits, accrued interest, loan repayments, capital and financial assets are combined inside balance sheets. In 2022, France’s Cour des comptes described its own allocation of a typical Livret A across several uses as theoretical. The exercise combined 2020 data, reconstructed banking aggregates and a uniform centralisation assumption. Cour des comptes, L’épargne réglementée, pages 55 to 57

The accurate formulation is therefore simple: France’s regulated savings contribute to the funding of several categories of assets. Assigning every cent in an individual account to one project would create a precision that the public data do not contain.

One savings account feeds two channels

The first channel runs through French banks. At the end of 2025, they retained €248.7 billion of non-centralised Livret A and LDDS deposits. French regulation requires minimum volumes of loans to small and medium-sized enterprises, the energy transition and the social and solidarity economy in relation to this funding.

The Banque de France calculated that the stock of eligible SME loans was equal to 254% of non-centralised Livret A and LDDS deposits, well above the regulatory minimum of 80%. The ratio does not mean that each euro in a savings account magically creates €2.54 of SME lending. It means that the banks’ total eligible SME loans amply cover the regulated deposits they retain. Those deposits remain fungible with the banks’ other sources of funding. Banque de France, 2025 report, pages 44 to 48

The second channel runs through the Savings Fund. At the end of 2025, the Livret A, LDDS and LEP held €699.1 billion in total. The fund centralised €406.5 billion of that amount. With €46.8 billion in capital and other funding, its balance sheet reached €453.3 billion. Caisse des Dépôts, 2025 report, pages 7 and 60

Five numbers explain the Savings Fund

On the asset side, the Savings Fund held €244.9 billion of loans and €208.4 billion of financial and other assets. Loans therefore represented slightly more than half of the balance sheet.

In 2025, the fund signed €41.7 billion of new loans: €22.9 billion for social housing and urban policy, €9.5 billion for France’s local public sector and €9.3 billion for newer uses, including €8.3 billion of refinancing for loans linked to the ecological transition. The Caisse des Dépôts attributes the construction or acquisition of 123,036 social homes to the year’s financing. A loan signed during the year is not necessarily an amount disbursed during that year. It should not be added to the outstanding loan stock as though the two figures measured the same thing. Caisse des Dépôts, 2025 report, pages 7 and 32

The €208.4 billion figure needs one clarification. The report separately shows a €203.3 billion financial portfolio, including €6.6 billion in current accounts, and €5.1 billion of other assets. Adding the two reconciles the presentations. There is no unexplained €5 billion gap in the accounts.

The portfolio earns income, hedges interest-rate and inflation risk, and provides assets that can be sold if deposits fall or demand for loans rises. At the end of 2025, it consisted of 89% bonds and 11% shares and funds.

Why the fund holds nearly €116bn of French government bonds

The Savings Fund held €53.9 billion of inflation-linked OATs and nearly €62 billion of nominal OATs. An OAT, or Obligation assimilable du Trésor, is France’s standard medium- or long-term government bond. The fund owned 17.6% of French inflation-linked debt in circulation and 2.8% of nominal OATs. Together, the two holdings amounted to approximately €115.9 billion. They represented close to 57% of the fund’s €203.3 billion financial portfolio. That percentage describes the public fund’s portfolio, not the assets of an individual saver. Caisse des Dépôts, 2025 report, page 45

Why does the French fund hold so much sovereign debt? An OAT performs three functions here.

First, buying the bond finances the French state directly when it is issued or supports secondary-market liquidity after issuance. The Savings Fund is a major creditor of the French Treasury. Its portfolio is separate from the government bonds held by the European Central Bank or the Banque de France. Each institution holds its own claim on the state.

Second, government bonds provide liquidity. High-quality sovereign securities can generally be sold more easily than social-housing loans made for several decades. They form a reserve that can be mobilised without waiting for the repayment of the buildings, water networks or infrastructure financed by the fund.

Third, inflation-linked OATs provide a hedge. The Livret A rate depends on inflation and the euro area’s €STR overnight rate. When inflation rises, the cost of centralised deposits can increase. Inflation-linked OAT principal and coupons adjust to a consumer-price index. The Caisse des Dépôts describes these bonds as essential to hedging the risk, alongside inflation swaps. Their role is therefore rooted in the structure of the fund’s liabilities, not merely in a patriotic or budgetary preference.

The arrangement still creates a notable concentration: the French state guarantees the savings, the Savings Fund manages part of the economic burden of that promise, and the same fund lends heavily to the French state. The loop is deliberate and publicly disclosed. It deserves scrutiny because a shock to French sovereign risk could affect both the value of some fund assets and the fiscal capacity of the ultimate guarantor.

How instant withdrawals coexist with 80-year loans

The apparent paradox is easy to see. A French saver can withdraw money quickly, while the Savings Fund makes loans with maturities of up to 80 years. Those loans would be impossible if every deposit had to be backed by cash available on the same day.

Pooling is the first layer. One household’s withdrawal is partly offset by another household’s deposit. A Livret A is individually liquid, while its aggregate balance is much more stable. At the end of 2025, 58% of Livrets A were more than ten years old and accounted for 63% of the balance held by individuals. Observed stability does not remove the risk of mass withdrawals, but it makes the risk possible to model. Banque de France, 2025 report, page 29

The fund then maintains several layers of liquidity: €6.6 billion in current accounts, a large securities portfolio, rules that allow centralisation to be adjusted, and ratios limiting the gap between funding and loans. The Banque de France identifies two regulatory thresholds, at 125% and 135%, whose breach can lead to a higher centralisation rate. Banque de France, 2025 report, page 40

Finally, the French government guarantee protects the principal and interest on regulated savings accounts. The guarantee does not make losses irrelevant to the balance sheet. It places the taxpayer at the end of the chain if the system’s own resources were to become insufficient. Banque de France, 2025 legal framework, Cour des comptes, pages 53 to 54

Where bond losses land

When interest rates rise, the market value of an existing bond falls. The decline is not deducted from a Livret A balance. The saver keeps the nominal balance and the right to withdraw it because the saver does not own the underlying OATs.

The risk remains inside the Savings Fund. Accounting treatment varies with the classification of the securities, and a sale can crystallise a gain or loss. Economically, a lasting decline in the value or income of assets can weigh on earnings, capital and future lending capacity. Conversely, higher rates gradually improve the return on new investments.

At the end of 2025, the Savings Fund reported €2.43 billion of recurring earnings, up from €455 million in 2024. One year’s earnings neither measure the maximum possible loss nor show the market value of every bond. They simply indicate that recorded income, margins and net capital gains exceeded recorded expenses in 2025. Caisse des Dépôts, 2025 report, page 61

French sovereign risk therefore requires a measured answer. The saver is insulated from the daily volatility of OATs, while the public balance sheet protecting the claim is exposed to them. If France were to restructure its debt, the outcome for the Savings Fund would depend on which bonds were affected, the haircut, the hedges, available capital and any government intervention. The OAT holding alone cannot be converted into a percentage loss for Livret A accounts. Our guide to sovereign defaults explains the general loss-allocation mechanisms.

The Livret A rate follows its own rule

Since 1 August 2026, the Livret A rate has been 1.7%. Its formula combines inflation excluding tobacco and the average €STR overnight rate, subject to rounding rules and a floor. For the relevant half-year, the Banque de France reported average inflation of 1.52% and an average €STR of 1.95%. Banque de France, decision of 15 July 2026

That 1.7% is not the average return earned by the social housing, SME loans or OATs funded by the system. It is the administered price of funding that comes with immediate liquidity, a tax exemption and a public guarantee. A direct comparison with the yield on a ten-year French government bond would ignore maturity, taxation, volatility and the guarantee. A meaningful comparison uses returns after tax and inflation for comparable levels of liquidity and risk.

The distributional question remains. Livret A accounts are held by 83% of France’s population, but balances are concentrated. In 2025, 15% of accounts held by individuals exceeded the statutory deposit ceiling because interest had accumulated, and those accounts represented 50% of the total balance. Better-funded households therefore receive more of the tax exemption and guarantee in euro terms. Banque de France, 2025 report, pages 27 to 29

A Banque de France working paper published in late 2025 also finds that euro-area bank deposit rates respond only partially and with a delay to increases in central-bank policy rates. The Livret A is partly removed from commercial deposit pricing, but its formula remains an economic-policy choice. It balances French savers’ purchasing power, the cost of public-interest loans and the financial position of the Savings Fund. Nicolas and Puy, Banque de France Working Paper No. 1029

Governance is the public-policy question

France’s Savings Fund performs a task that markets would struggle to provide on the same terms: very long loans, sometimes indexed to the Livret A rate, for public and social projects. Its financial portfolio supports the transformation and contributes to earnings. The structure has an economic logic.

That logic still leaves choices to examine.

• Sovereign concentration: how much debt issued by its own guarantor can a state-guaranteed fund accumulate before the two balance sheets become too interdependent?
• New uses: does each extension into defence, infrastructure or the transition address a clearly identified financing gap?
• Return: do new loans adequately compensate the fund for its funding cost, risk and liquidity needs?
• Transparency: do the ratios imposed on French banks describe the use of non-centralised deposits precisely enough?
• Distribution: do the tax cost and guarantee benefit the households for whom this popular savings product is intended?

In 2022, the Cour des comptes already set out a cautious test. Any extension should preserve social-housing finance, serve a public-interest purpose, avoid displacing available private funding and respect return, liquidity and safety constraints. The 2025 figures make the issue more concrete because newer uses rose sharply. Cour des comptes, summary and recommendations

The final picture

A substantial part of France’s regulated savings does indirectly finance French government debt. The Savings Fund held nearly €116 billion of OATs at the end of 2025. Social housing still accounted for the largest block of its loans, and French banks reported eligible SME lending far above the required ratio.

It would nevertheless be misleading to assign one destination to each euro in a Livret A. The product is not a fund in which the saver chooses the assets. It is a liquid, guaranteed claim supported by a set of balance sheets that allocate pooled funding among French banks, public-interest loans and a financial portfolio.

The useful question is therefore the price, risk and governance of a specifically French public transformation: €440 billion held in individual Livrets A becomes a collective resource able to finance assets that could never be made individually liquid on demand.
