The Next Crisis: Europe’s Fiscal Reckoning After the Deflationary Bust

As the deflationary bust gives way to public-sector overreach, Europe’s fragmented fiscal union faces its greatest test yet — a coming sovereign debt reckoning that could decide the fate of the Euro

Introduction

The global economy may be approaching a perilous inflection point. After a period of inflationary pressure and aggressive monetary tightening, some analysts (including “yours-truly”) foresee a sharp deflationary bust – a hard economic downturn that quells inflation but at the cost of a recession. Such a bust would not be the end of the story, however. It would merely set the stage for the next crisis: a sovereign debt reckoning, centered in Europe. As private-sector borrowers retrench in a bust, governments historically step in to cushion the blow, running up large deficits. Public debt levels, already elevated since the pandemic, would spike even higher. This public debt deluge following the bust could expose the weakest links in the global financial system. All signs point to Europe as the likely epicenter of the coming sovereign debt crisis, due to the unique fragilities of its monetary union.

In this article, I bridge the deflationary bust thesis to the looming threat of a European sovereign debt crisis. I will explore how a deflationary recession would drive government debt sharply upward, why the eurozone’s structural flaws make it especially vulnerable, and how the situation today differs from the last eurozone crisis a decade ago. I’ll compare Europe’s adjustment mechanisms (or lack thereof) with the United States’ and illustrate the risks with three charts. In short, unless Europe embraces significant reform – moving toward either deeper fiscal integration or some form of orderly adjustment – the next crisis will severely test the cohesion of the euro itself.

From Deflationary Bust to Debt Deluge

A deflationary bust would likely compel governments to unleash fiscal support on a massive scale. In a recession or credit crunch, the private sector cuts back spending to repair balance sheets (so-called deleveraging). If everyone saves at once, aggregate demand collapses, worsening the downturn. Governments then act as spender of last resort, running large deficits to counteract the private contraction. We saw this dynamic after the 2008 financial crisis and again during the 2020 pandemic shock: public debt levels exploded as fiscal authorities intervened. The same will happen in the next bust – perhaps even more forcefully, given today’s higher starting debts and politically limited central banks.

Across advanced economies, public debt ratios are already near record highs, and a new bust will push them higher still. Europe is a prime example. In 2024 – even before any severe recession – the average eurozone budget balance was about –3.1% of GDP, and debt stood at 87.4% of GDP[1][2]. Those figures exceed the EU’s own fiscal rules (the Stability and Growth Pact limits of a 3% deficit and 60% debt-to-GDP) even in what has been a relatively calm period. The next recession will blow these deficits out further as revenues fall and safety-net spending rises. Governments will also likely roll out stimulus measures to fight the downturn, adding even more red ink. Public-sector debt, in sum, is poised to surge in the deflationary bust’s wake, as states absorb the financial losses of households and firms.

The result is that many European countries will enter the post-bust era deep in a fiscal danger zone. Their debt and deficit metrics will violate the Maastricht Treaty thresholds by a wide margin. Chart 1 illustrates the landscape of EU public finances as of 2024, plotting each country’s government debt-to-GDP against its budget balance. The red lines mark the Maastricht limits (60% debt and –3% deficit). Every country above and to the right of those lines is in the “fiscal red zone,” exceeding both debt and deficit guidelines. Notably, several major economies fall into this high-risk quadrant – a worrisome harbinger if financial markets turn skittish in a downturn.

Chart 1: 2024 public-sector fiscal balances vs. debt levels for EU countries. Many nations are in the “fiscal red zone” beyond the Maastricht ceilings (to the bottom-right of the dashed red lines), meaning debt over 60% of GDP and deficits worse than –3% of GDP. These vulnerable cases include large economies like France, Spain, Italy, Belgium, Austria and Finland, all of whom carried debt well above 60% of GDP and ran deficits above 3% in 2024. In contrast, a few countries (upper-left quadrant) maintained low debt and near-balanced budgets – for example, Denmark, Ireland, and Greece, which managed a small surplus[3][4].
