Germany's financing costs in a major long-term bond sale are poised to reach a 15-year peak as governments worldwide continue to grapple with inflation and investors demand higher risk premiums for lending. According to sources familiar with the matter who requested anonymity, Germany is marketing bonds maturing in August 2056 through a bank syndicate, with the coupon priced at 0.4 basis points above the comparable 2054 issue, which currently trades at a yield of 3.77%. The final pricing is expected to be completed later on Tuesday.

Last month, Germany conducted a smaller auction of 30-year bonds at a yield of 3.64%, marking the highest level for a regular auction of that maturity since 2011. However, with global markets weakening further in recent weeks, German bond yields have climbed back to levels not seen since the eurozone debt crisis. The worldwide bond sell-off has been driven by expanding government fiscal spending and lingering inflationary pressures following this year's oil price shock.

Last week, the U.S. 30-year Treasury auction saw its highest issuance rate in 25 years, while the 10-year benchmark note's borrowing costs also reached their highest since 2007. Christoph Rieger, head of rates and credit research at Commerzbank, noted that Tuesday's syndicated sale is expected to raise up to 3.5 billion euros, equivalent to approximately 4.1 billion U.S. dollars.

His colleague Hauke Siemssen wrote in a research note last month that Germany's financing needs will rise significantly in 2027, with the draft budget showing net borrowing requirements of 204 billion euros. Siemssen projects that net issuance of German government bonds will hit a record 163 billion euros next year, up from roughly 137 billion euros in 2026, while total issuance is also expected to reach an all-time high of approximately 400 billion euros.

The surge in borrowing stems from increased defense and infrastructure spending, alongside 238 billion euros in bonds maturing. However, not all funding will come from bond issuance alone. Siemssen indicated that short-term treasury bills, cash reserves, asset sales, and transfers from the state-owned development bank KfW could serve as supplementary funding sources.

In this syndicated sale, Germany is tapping the bond first issued in March of last year, which attracted 36 billion euros in subscriptions for a 6 billion euro offering. When the bond was reopened in May, it saw similar demand levels, with yields at the time hovering just below 15-year highs.

It is unusual for Germany to restart syndicated bond sales so early after the summer lull that typically characterizes European sovereign debt issuance. Data shows that since 2015, Finland has usually been the first to return to the syndicated market after the summer break. While syndicated issuance typically carries higher costs than public auctions, it allows governments to raise substantial funds quickly while broadening the investor base.

The lead managers for this German bond sale include Barclays, BNP Paribas, Citigroup, Deutsche Bank, JPMorgan, and NatWest Markets.
