Greece will cease to be the euro zone's most indebted country by the end of this year as its public debt will fall below Italy's, according to two sources and data from Italy's budget plan. Greek debt is estimated to decline to around 137% of gross domestic product this year from 145.9% in 2025, two senior officials told Reuters. By contrast, Italy expects its debt to peak at 138.6% in 2026, up 1.5 percentage points from 137.1% of GDP in 2025, under the Treasury's multi-year budget plan published this week.
