Bulgaria borrowed a fresh 2.25 billion euros on international markets in a deal on September 29, the finance ministry says. It last sold debt abroad in July, raising 2.5 billion euros then.

The ministry topped up three eurobond issues sold under its medium-term global debt programme. Bonds due in 2031 got an extra 1 billion euros. Those due in September 2034 rose by 750 million euros. The longest bonds, due in 2044, brought in 500 million euros.

Orders topped 5.5 billion euros, including 265 million euros from the joint lead managers themselves. The ministry says that despite shaky global markets, the deal drew strong interest, and demand was high enough to let it cut the spread from its starting level.

For the 2031 and September 2034 bonds, the spread fell by 20 basis points; for the 2044 bonds, by 15. The final spread over the mid-swap rate came to 60 basis points for the 2031 bonds, 95 for the September 2034 bonds and 160 for the 2044 bonds.

The yield stood at 4.235% for the 2031 bonds, 4.608% for the 2034 bonds and 5.325% for the longest-dated ones.

Since the start of 2026, Bulgaria has borrowed 6.5 billion euros in total. BTA reports that 4.75 billion euros of that came from international markets and 1.755 billion euros from the domestic market.

This year's state budget law caps new government debt at 10.1 billion euros. That figure includes borrowing of up to 3.261 billion euros under the EU's SAFE fund (Security Action for Europe), which is meant to help build up the defence industry. The finance ministry says the new debt stays within that cap.

Bulgaria expects its government debt to reach 37.7 billion euros by the end of the year, equal to 30.1% of gross domestic product.
