Berlin – The German state wanted to raise fresh capital via the bond market this week. The plan was to issue around five billion euros over ten-year government bonds. But investor demand fell well short of expectations. At the same time, yields rose noticeably. This is a clear warning signal for fiscal policy in Berlin: the financing of German government debt could become significantly more expensive in the future.

The federal government tried on Wednesday to increase an existing ten-year federal bond. According to the Finance Agency, however, only bids for around 4.5 billion euros were received. In the end, bonds worth about 3.8 billion euros were allocated. The average yield was 2.89 percent.

By comparison, at the previous auction of the same bond in mid-February, the average yield had been 2.73 percent. The government had to offer investors higher interest rates while at the same time there was less demand – a combination that increases the state's financing costs.

An acute financing crisis is still a long way off in Germany. Nevertheless, the result is considered politically sensitive. For 2026, the federal government plans to raise around 512 billion euros on the capital market via various government bonds – including green bonds.

In the ten-year German government bond segment alone, about 82 billion euros are to be collected. This maturity segment in particular is considered particularly important because it serves as a reference for long-term interest rates in the euro area. If yields rise here and demand declines at the same time, financing becomes more expensive for the state over a longer period of time.

The development comes at a time of increasing geopolitical tensions. The escalation in the Middle East and disruptions around the important shipping route through the Strait of Hormuz have recently led to rising energy prices. These, in turn, are increasing concerns about new inflation on the financial markets.

Accordingly, the yield on ten-year German government bonds climbed to just under three percent at times – the highest level since autumn 2023. The last time there was a permanent interest rate level above three percent was in 2011.

In addition, there is a structural change in the market. For a long time, German government bonds were considered a particularly safe haven for investors. In times of economic uncertainty, large amounts of capital flowed into these securities.

But this status seems to be gradually changing. Investors are sometimes switching to other safe forms of investment – such as the Swiss franc or gold. At the same time, the European Central Bank continues to reduce its bond holdings, which had been greatly expanded during the Corona crisis.

The consequences of rising yields are not limited to the national budget. The yield on the ten-year German government bond is considered an important reference value for long-term financing in the euro area. When this so-called risk-free interest rate rises, mortgages, corporate loans and other financing often also become more expensive.

Thus, a development in the bond market could also influence the real estate market, investments by companies and the financing of many projects in the long term.

A market that corrects

expectations

can be no talk of an acute crisis yet. Nevertheless, the situation reminds observers of earlier phases in which rising interest rates were the first warning signals for fiscal policy.

The difference to the past, however, is that politicians are currently planning a significant increase in public debt – both nationally and at the European level. At the same time, the capital market seems to be increasingly critical of the conditions under which it continues to make money available to states.

The latest auction thus shows one thing above all: the times of almost unlimited and extremely cheap government financing could slowly come to an end.
