The spectacular increase in funding costs of Germany this week is far from being a rejection of Bazooka fiscal by Friedrich Merz, according to investors, believing that the expense plan of the waiting chancellor can increase growth without stretching the finances of Berlin beyond a lasting level.
The German bunds have had their biggest sale of a day for decades on Wednesday while the markets adapted to a spectacular change in German fiscal policy, and a massive increase in the debt issue, according to the “everything you need” Merz plan to spend for defense and infrastructure.
Despite the installation at the end of the week, the 10-year bundle was high above 2.8% on Friday, after starting the week below 2.5%.
“The German authorities finally woke up to the fact that they had to take drastic measures to relaunch their economy” and strengthen their defense, “said Nicolas Trindade, head of the main portfolio at the Axa investment branch. “This is positive for medium -term growth, and Germany certainly has enough budgetary space to adapt to these very large additional expenses.”
Economists on Thursday morning began to revise their growth forecasts. The BNP now provides that German GDP will increase by 0.7% this year and 0.8% in 2026, instead of an increase of 0.2% and 0.5%. The raising of expectations also contributed to led to German actions on Thursday to a record.
The increase in Bund’s yields and equity prices was “an approval of the positive impact that this change in policy will have on German growth,” said Gordon Shannon, funding for Twenty-Four Asset Management.
The yields increased while merchants have decided to reduce their expectations for the rate drops of the European Central Bank on stronger prospects, even before Thursday’s meeting made the reference rate of the euro zone down a quarter of a point to 2.5%. Traders are now entirely prices in another drop of a quarter of a point, depending on the levels of Swaps markets.
The other major factor in the performance leap, said investors, was the massive increase in Bund’s issuance, an asset that establishes a reference for the debt prices in the euro zone but has often been in shortage due to the “debt braking” of Germany limiting the government’s loan.
This rarity – also due to central banks holding a large part of the actions available – is one of the reasons why Bund yields have exchanged below zero for prolonged periods in the last decade.
The traders began to bet seriously on a higher Bund program last year, speculation, debt brake reform, taking for the first time Bund yields at 10 years higher than the euro rate for exchanges of interest in euros, investors were preparing for more offer.
Higher yields reflect the risk that the broader market in the euro area debt may have “difficulties” to absorb the emission offer “If the new tax cutting room is used,” said Felix Feather, economist at Asset Manager Aberdeen.
It was not, he said, fired by a perceived increase in credit risk. “The possibility that Germany defects or restructuring its debt is not a concern for us at this stage,” he said.
It was kilometers away, the investors said, from the UK experience in 2022, when the “mini” unhappy budget of Liz Truss sparked a gilts crisis. A similar extreme scenario in Germany would have ramifications in the euro zone.
“Germany is the backbone of the euro zone. If the German budget becomes uncontrollable, the euro will be toast, “said Bert Flossbach, co-founder and investment director of the German active director Flossbach von Storch.
The country’s light debt burden – with debt amounting to around 63% of GDP, compared to almost 100% or greater than 100% for some other major economies – means that such a scenario is considered to be very improbable.
Investors are more concern about the potential repercussions of higher change in borrowing costs for other countries in the euro zone which are already much higher.

The propagation between German yields and those of other borrowers in the euro zone such as France and Italy remained stable this week, a net contrast with historical moments of stress such as the debt crisis in the euro zone. But the increase in locking yields with Germany will always exert pressure on countries with larger debt charges.
British bonds were taken in the sale, the 10 -year yield of over 4.6% on Friday, against its lowest months last month by less than 4.4%, because it only made weeks before the government made a declaration on public finances on March 26.
The increase in yields has exerted more pressure on Chancellor Rachel Reeves to “deliver tax increases or expense reductions to remain in its tax rules,” said Mark Dowding, director of investment for fixed income at RBC BlueBay Asset Management.
A key factor in the place where the bunds go from here will be whether German economic growth emerges.
In one of the most optimistic prospects, the German economic reflection group IMK predicted that the German economy in the medium term could return to growth rates of up to 2% – a rate of expansion slightly higher than 1.8% per year observed during the 15 years preceding the pandemic.
Analysts also warn that an investment wave funded by debt will not be sufficient to overcome the persistent growth crisis of Germany, which many attribute to deeper problems such as aging workforce, bureaucracy and an obsolete industrial structure.
The manufacturing sector depending on export is also touched by geopolitical tensions. “Larger deficits alone will only resolve any of the [those challenges]”Said Oliver Rakau, chief economist in Germany at Oxford Economics.
But other analysts are more positive. Bank of America described the tax recovery to “change the game” of German growth which, associated with the broader bond issue, underlined a “significantly higher” forecast for the bundle yield at 10 years that it had previously planned.
“Bund’s yields are not out of fear, because Germany has a lot of budgetary space,” said Mahmood Pradhan, world macro chief in Amundi. “The markets deal with this as a positive growth result.”
