EUR 6.0 billion for the new 30-year Belgian OLO 107
On 4th February 2026, the Belgian Debt Agency issued its second OLO syndicated benchmark transaction for the year: the new 30-year OLO maturing 22 June 2056. The OLO 107 has an annual coupon of 4.35% and was issued at a price of 99.938%, giving a reoffer yield of 4.355%.
The transaction saw strong participation from the outset, with the orderbook growing to over EUR 112 billion at closing, which encouraged the Belgian Debt Agency to set the new issue size at EUR 6 billion, the largest 30-year benchmark issued by the Kingdom to date.
Following this 30-year transaction, the Belgian Debt Agency has now completed two of the three anticipated OLO fixed-rate benchmarks for 2026. This follows the new EUR 8 billion 10-year benchmark OLO launched in January via syndication. The third new benchmark bond is expected to be a five-year OLO.
With this second syndication, the Belgian Debt Agency has already raised 27% of the planned 2026 OLO issuance.
More details on the new 30-year OLO are available in the annex.
