Paris unrest poses contamination risks to bond yields beyond France

Euro area sovereign bonds have been under sustained pressure since late September, with France at the epicentre, as budget wrangling and a weekend of riots in Paris and other cities make headlines globally.

The French 10-year Obligations Assimilables du Trésor (OAT) yield reached 5% on Oct 21, its highest level since 2002, while the 10-Year German Bund traded near 3.4%, pushing the Franco-German spread to about 160 basis points, its widest since the 2011–2012 euro debt crisis. The head of the French Central Bank has warned that without action, the country risks being “strangled by interest rates”.

Over the weekend of Oct 17–18, the political pressure escalated sharply. More than half a million people took to the streets across France to protest the rising cost of living and fuel prices, with demonstrations degenerating into riots in Paris, Marseille and other cities. Buildings were torched and shopfronts smashed in the country’s worst unrest in years, with some 2,000 businesses affected.

Uncertainty about France’s difficult fiscal position is not new. France’s fiscal arithmetic looks difficult by most measures. France’s forecast 2026 deficit is 5.4% of GDP, versus the 2.3% the government itself estimates would stabilise debt, and well above the EU’s 3% of GDP Stability and Growth Pact threshold.

Unfortunately, the latest developments come at an awkward time given the upward pressure we are currently seeing on longer-dated bond yields globally.

On Oct 1, the government unveiled a budget of EUR54 billion ($77.49 billion) in spending cuts and tax increases. However, French voters have little stomach for austerity, and the country’s fragmented parliament, with no stable governing majority, makes securing votes for politically sensitive issues extremely difficult, raising the prospect that the government will have to resort to constitutional tools such as Article 49.3 to force the measures through.

The minority government has typically relied on these exceptional executive procedures to push budgets through. The National Assembly vote on the revenue section of the 2027 draft budget is due this week, and investors are bracing for Moody’s long-awaited credit rating review on Friday, with a potential downgrade adding to the pressure on French government bonds.

More importantly, the lack of a credible pension reform plan from any political party remains the key issue, given its dire fiscal position. France’s interest rate on public debt is projected to exceed nominal GDP growth by 2029, which means the country will have to run a primary surplus just to stabilise debt, an almost impossible threshold at the moment, as a growing share of public spending such as debt servicing, pensions, public healthcare, social transfers and defence is politically ring-fenced.

Furthermore, its tax burden at 43.5% of GDP is the second highest in the OECD, leaving little room for positive revenue adjustment as a possible solution.

If fiscal policy does not deliver the adjustment, market repricing may increasingly become the forcing mechanism, a major risk as some 58% of French OAT medium- and long-term government bonds are held by international investors.

Some reports have highlighted hedge funds unwinding positions as a key driver of the recent widening in French spreads. While cleaner positioning may help stabilise the market, the risk is that long-standing foreign holders of French debt, notably Japanese investors, could reduce their exposure more aggressively.

Furthermore, foreign investors in French bonds tend to hold government debt across Europe. This raises the risk of contagion from France to other markets, including Italy.

Can the European Central Bank (ECB) intervene, if needed? In our view, the ECB is unlikely to buy French debt without conditions, barring a systemic crisis threatening the monetary union as a whole. The trigger for ECB intervention would not be the OAT–Bund spread in isolation, but signs of contagion that impair monetary policy transmission, including a widening of short-dated peripheral spreads.

In our view, any intervention would unfold in stages. The first line of defence would be verbal. The ECB president signalled this week that all tools remain available. Policymakers could also guide towards fewer rate hikes if the outlook deteriorated further.

If tensions persisted, the ECB could bolster euro-area liquidity and market functioning through a backstop for banks or the repo market. Another option would be to halt Quantitative Tightening (QT) to stop shrinking the ECB’s balance sheet.

Only if market stress seriously threatened monetary-policy transmission would it consider buying government bonds under the Transmission Protection Instrument (TPI), a step that carries a much higher political and operational bar.

We are underweight core Euro area sovereign bonds, and neutral on periphery Euro government bonds. EUR investment-grade credit spreads have also widened in sympathy, as France represents 20% of the EUR investment-grade index while pan-European financials account for 33%.

A French-specific sovereign premium would have little direct impact on Asia. However, persistent pressure on French yields could risk contaminating the broader sovereign complex, including Asia.

In this situation, the Indonesian rupiah and Indian rupee are likely to be the most vulnerable due to likely government bond and equity outflows.

The Chinese yuan (CNY) and Singapore dollar (SGD) are likely to be the most stable currencies in Asia because of strong government fundamentals, such as high forex reserves and large current account surpluses. Their government bonds are highly sought after for their safe-haven status.

Although the New Taiwan dollar (TWD) also shares similarly strong fiscal fundamentals as the SGD and CNY, it will likely be affected by equity outflows from its high-beta equity market, now the biggest in Asia, if the French fiscal crisis develops into a Euro area issue.
