September 25 marked a significant symbolic milestone for French public finances, with the 10-year borrowing rate hitting 4.73%. This level, unseen since the 2008 financial crisis, reflects growing market skepticism regarding the State's creditworthiness. Several factors explain this strain, notably a complex global economic climate and a specific deterioration in the perception of French sovereign risk. A clear sign of this nervousness is that the yield spread against German bonds—the famous "spread"—has surpassed the 100-basis-point threshold, leaving France in a less favorable position than Italy in the bond market.
This situation presents holders of life insurance, the French public's favorite investment vehicle, with a conflicting reality. While rising rates may allow insurers to reinvest in higher-yielding assets in the long term, the weight of existing bond portfolios has become problematic. With public debt reaching €3,600 billion, insurers hold a significant share of securities issued during an era of low interest rates. Should there be a massive withdrawal of savings by individuals, insurance companies would be forced to liquidate these older bonds at a loss, undermining the stability of "fonds en euros" (guaranteed capital funds).
The core issue lies in the sustainability of public debt amid persistent deficits and surging interest expenses. The government faces a complex dilemma: the budget adjustments required to restore public finances are clashing with political instability, which restricts legislative maneuvering room. This dynamic creates a vicious cycle where rising rates increase debt burdens, fueling investor fears, who in turn demand higher yields to compensate for the risks associated with the French economy.
Faced with these systemic risks, the French regulatory framework, particularly the loi Sapin 2, provides strict safeguards. In the event of a serious threat to financial stability, authorities have the power to temporarily suspend withdrawals, transfers, or payments on life insurance policies to prevent panic. This possibility of freezing capital highlights, by contrast, the "safe haven" value that some investors now attribute to decentralized digital assets.
In this climate of volatility, Bitcoin is emerging as an alternative for savers seeking protection against administrative decisions. Unlike traditional financial products, this digital currency, when held in self-custody, remains beyond the reach of centralized entities. Its mathematically limited supply, independent of central bank monetary policies, makes it a decorrelated asset, increasingly integrated into modern wealth management strategies to diversify risks linked to sovereign debt.
