Italian borrowing costs hit three-year high as spread widens to 118.5 points
The gap between Italian and German government bonds has widened to levels not seen since early 2025, raising the cost of financing Italy's public debt. The spread between the 10-year BTP and the German Bund closed at 118.5 points on 1 October, up 15.6 points in a single session.
The yield on the Italian 10-year bond rose to 4.69%, the highest level in more than three years. At the same time, the Bund yield fell to 3.5%, a drop of 7.8 points. The spread measures the difference in yield between the two bonds and reflects the premium investors demand to hold Italian debt rather than German debt, which they consider safer.
Why investors are selling Italian bonds
The European Central Bank (ECB) linked the rise in yields to pressures on public finances across the euro area. The Italian Treasury faces questions about the sustainability of debt that has surpassed €3.2 trillion. Moody's confirmed Italy's Baa2 rating in September but projects the debt-to-GDP ratio will stabilize at 138% in 2026 and 2027, the highest in Europe.
Oil prices above $100 per barrel have stoked inflation, forcing central banks to keep interest rates high. The ECB raised the deposit rate to 2.50% in September and has signaled further increases may be necessary. Higher rates increase borrowing costs for governments with high debt loads, such as Italy.
The German government forecasts growth of 1.3% for 2026, but its own fiscal deficit is expected to rise to 3.7% of GDP, the highest in decades outside of a recession. Investors seeking safety have driven up demand for Bunds, pushing their prices higher and yields lower, which in turn widens the spread with Italy.
Impact on Italian finances and households
A higher spread increases the interest payments Italy must make on new debt and when refinancing existing bonds. This could reduce the funds available for other public spending. The annual cost of financing Italian debt has risen by about one percentage point compared to last year, reaching roughly 3.5%.
For households, higher government borrowing costs often translate to higher interest rates on mortgages and consumer loans. Banks tie their lending rates to sovereign bond yields, so the 4.69% yield on the 10-year BTP signals that credit will remain expensive.
Broader market pressures
The pressure on Italian bonds reflects a global trend. Yields have risen on US Treasuries, French OATs and UK gilts as investors demand higher returns for holding sovereign debt. The French spread over German bonds has also widened, reaching 133 points, indicating that concerns about public finances are not limited to Italy.
The spread had narrowed to 59 points in January 2026 and stood at around 92 to 103 points at the end of September. The rapid movement to 118.5 points signals a shift in market sentiment, with investors retreating to assets they perceive as safer amid uncertainty about inflation and the economic outlook.
The Italian Treasury, working on the 2027 Budget Law, aims to stabilize the debt and support growth, with GDP projected to grow around 0.8% to 0.9% in 2026. The next auction of Italian government bonds will test whether investors accept the current yield levels or demand an even higher premium.
