Europe’s Coming Bond Avalanche Will Test the ECB

European governments are set to unleash a deluge of bonds into markets this year. Investors will demand either a further shift higher in yields or a substantial improvement in the region’s inflation outlook to digest the coming wave of supply, adding to the already daunting monetary policy challenges facing the European Central Bank.

The 10 largest euro nations are expected to sell some €1.3 trillion ($1.38 trillion) of sovereign bonds this year. A little over half of that will be new money, after allowing for maturing debt. It's a scarily large jump in net new supply of around €340 billion, according to analysts at NatWest Group Plc. Adding to the pressure, the ECB’s quantitative tightening process starting in March will add at least an extra €150 billion of bonds markets will need to absorb this year.

Someone, somewhere is going to have to step up and buy all of these new securities. Unfortunately, the timing is poor as central banks globally have become net sellers of the holdings they accumulated in the wake of the global financial crisis and to fund stimulus measures to address the pandemic.

Austria, Slovenia, Ireland and Portugal have all launched syndicated new issues this week, with France and Italy likely close behind. It’s going to be a busy month as sovereign borrowers will want to get a head start on their heavy issuance calendars.

The slowdown in German annual inflation, to 9.6% in December from October’s peak of 10.4%, is most welcome, as is the unexpected deceleration in French consumer prices. Inflation in the euro zone remains a long, long way from the ECB’s 2% target, but the road back to price normality has to start somewhere. Enticing investors to step up to the plate and take down even large swaths of European sovereign debt relies on an improving inflationary backdrop. Otherwise, yields will just have to keep rising to attract sufficient demand which risks straining the limits of the European Union’s cohesiveness.

The biggest additional net borrower will be Germany, which has dramatically altered its approach to its financing. It will look to sell between €300 billion and €350 billion of bonds this year, about half of which will be new money. That is close to triple last year’s net requirement. Its Economic Stabilization fund has identified some €200 billion needed to help address the fallout from the huge energy price squeeze following Russia's invasion of Ukraine.
