The Synchronisation of the Wave of Protests Across Europe: How Interest Rate Cycles and the Cost-of-Living Crisis Are Fuelling a Wave of Transnational Protests

Automatically translated. Read the Chinese original.

Around 17 October 2026, large-scale street protests erupted almost simultaneously in several countries, including France, Spain, Italy, Portugal and Belgium, with a partial curfew imposed in certain areas of Paris. Was this simultaneous wave of protests across multiple countries the result of ‘contagion’ via social media, or did everyone receive the same bill? This article examines the September inflation figures for each country, the European Central Bank’s interest rate hikes and fiscal space, to analyse the common causes of this wave of protests, the cases of Spain and France, and possible scenarios for how the situation might unfold this winter.

The data in this article is current as at 20 October 2026; the probabilities of the scenarios are analytical estimates and do not constitute investment advice.

Key Findings

Macroeconomic factors share a high degree of commonality: This wave of cross-border protests did not erupt by chance, but stems from a common broader context. The conflict in the Middle East (escalating tensions between the US and Iran, and the prolonged blockage of the Strait of Hormuz) has pushed Brent crude oil prices to around US$110 (US$110.48 as at 20 October), compounded by the European Central Bank (ECB) resuming interest rate hikes, the pressures from energy, transport and the cost of living all converged simultaneously across many European countries at the end of the third quarter of 2026.
The weighting of ‘shared triggers’ far exceeds that of ‘emotional contagion’: Social media has certainly accelerated the cross-border replication of protest forms such as roadblocks, night-time standoffs and student walkouts; however, the timing of people taking to the streets in various countries closely aligns with the surge in consumer price index (CPI) figures in September, and the underlying driver remains the economic burden.
The ‘asymmetric structure’ of ‘soaring energy prices and stable core inflation’: Core inflation in France stands at just 1.5%, Core inflation in the eurozone stood at just 2.5%… in stark contrast to the widespread inflation of 2022. The cost-of-living squeeze is concentrated on essential expenses such as fuel for commuting, winter heating and rent, directly affecting young people with limited financial reserves; this is the economic rationale behind students taking the lead in this round of protests.
The European Central Bank is caught in a ‘policy mismatch’: On 10 September, the ECB raised interest rates by 25 basis points (deposit rate 2.50%(the first such increase since 2023), with the market pricing in the possibility of a further rise in December. Interest rate rises do not increase oil supply; rather, they push up the cost of mortgages (the overall cost of new housing loans 3.54%), corporate lending (3.80%) and the cost of servicing government debt; all three transmission channels are supported by official ECB data.
Situational Judgement: Base-case scenario (probability approximately 50%) are intermittent protests that have become a regular feature of weekends during the winter months; they are unlikely to topple the government in the short term; the escalation and spread resulting from deteriorating geopolitical conditions, and the natural subsiding of tensions brought about by geopolitical détente, each have their own course. 25% the possibility that...

I. Factual Background: The Spatio-Temporal Alignment of the Wave of Protests and Macroeconomic Data

1.1 Timeline and Scope of the Protests

Based on a summary of The Guardian’s explanatory piece of 18 October, and reports by CNN on 19 October and CNBC on 20 October:

Outbreak nodes: Around 17 October 2026, large-scale street demonstrations broke out simultaneously in several major European economies, with the situation rapidly escalating into riots in some areas.
Areas affected: France is at the epicentre of this unrest, with partial curfews already in place in some districts of Paris; coordinated protests have emerged in Belgium, Italy, Portugal, Spain, Albania and other countries.
Group characteristics: Secondary school pupils and university students have become a significant force on the streets in France and southern Europe, calling for measures to curb the cost of living, halt rent rises, improve school facilities and oppose cuts to public spending.

1.2 Comparison of inflation figures across countries

Data source: Eurostat and national statistical offices, cross-checked by TradingEconomics; data as at September 2026.

Country / Region	September CPI year-on-year	August (previous figure)	Core inflation / Key energy sub-components	Billing Characteristics
Spain	4.9%	4.3%	Year-on-year figures for the transport sub-sector +10.5%(Of which diesel in August, year-on-year) +30.3%); housing and public utilities, year-on-year +7.2%	The CPI was the highest among the five samples, with transport and housing costs showing a marked deterioration
Italy	4.2%	3.2%	Inflation jumped by 1.0 percentage points in a single month	A rebound in fixed expenditure on energy and food
The eurozone as a whole	3.8%	3.2%	Energy breakdown year-on-year +18.9%(a new high since January 2023); core inflation stood at just 2.5%	Typical inflation driven by external energy factors
France (HICP)	3.4%	2.6%	Energy breakdown year-on-year +21.3%, petroleum products +36.2%；Core inflation stands at just 1.5 per cent	Domestic demand is sluggish, and the impact of imported oil prices is severe
Germany	3.3%	2.9%	A general, moderate upward trend	Industrial energy consumption is under pressure, whilst protests have been slow to emerge

Inflation figures for major European countries in September 2026, compared with energy and key sub-categories

Figure 1France and Spain, where protests first broke out, are precisely the countries experiencing the most severe and rapid surge in energy inflation; core inflation in both countries remains relatively stable, with pressure concentrated on energy and essential household bills.

Key insights: France and Spain, where protests broke out earliest and were most intense, happened to be the countries that experienced the sharpest surge in inflation and the largest increases in the energy sub-index between August and September (France’s HICP rose from 2.6 per cent to 3.4 per cent, whilst Spain’s rose from 4.3 per cent to 4.9 per cent). It should be noted that this observation is based on only two of the five countries in the sample and constitutes evidence that is ‘consistent with the mechanism’, rather than a rigorous statistical test; whilst the rise in energy prices in Germany was relatively moderate, protests also spread there, suggesting that, in addition to common triggers, local factors are also at play in each country. Households’ perception of inflation often stems from their monthly fuel, electricity and water bills, and the timing of the protests aligns with the time lag in these bill shocks.

1.3 The European Central Bank and the Sovereign Debt Crisis

Monetary policy: The European Central Bank on 10 September 2026A 25-basis-point interest rate rise was announced, bringing the main refinancing rate to 2.65%, the interest rate on the deposit facility has risen to 2.50%This marks the first interest rate rise since 2023 (following eight consecutive rate cuts between June 2024 and June 2025). The minutes of the monetary policy meeting published on 8 October acknowledged upward risks to inflation but, constrained by the conflicts in Ukraine and the Middle East, deliberately avoided providing guidance on the medium-term interest rate path. The interest rate derivatives market has already begun to price in a further rate rise in December.
Widening sovereign debt spreads: The yield on 10-year French government bonds is approaching Highest level in 24 years, the fiscal deficit widened further between January and August 2026; yields on Spanish 10-year government bonds hovered at their highest levels since 2013. The fiscal manoeuvre room of both peripheral and core European countries is constrained by capital markets.

II. Why does ‘synchronisation’ occur: the three-tier mechanism of protest waves

Research into the 2011 Arab Spring, the 15-M movement in Spain, the Occupy Wall Street movement, and the wave of protests that swept across numerous countries in 2019 indicates that the formation of transnational protest waves depends on the coupling of several structural levels:

Level	Mechanism	Key elements
First floor	Common macro-level triggers (fuel, leading to simultaneous outbreaks)	The conflict in the Middle East has kept Brent crude trading at the upper end of the US$100–110 range, with energy bills hitting everyone equally; the European Central Bank has raised interest rates, leading to a general tightening of borrowing and debt-servicing costs
Second floor	The Transnational Replication of Forms of Resistance (Accelerator)	Social media rapidly disseminated images and tactics relating to roadblocks, localised curfews and student rallies; young people across various countries developed a sense of collective efficacy, feeling that ‘neighbouring countries are also protesting’.
Third floor	Political and Fiscal Vacuum (Amplifier)	Party divisions and a weak coalition government towards the end of Macron’s term; high government bond yields have left no room for energy subsidies, making it difficult for the government both to foot the bill and to crack down firmly.

A three-tier mechanism operates in a top-down manner: shared bills foster a widespread sense of deprivation, social media provides a means of mobilisation, and the political vacuum allows the protests to persist and continue.

The Three-Tiered Drivers and Transmission Mechanisms of the Wave of Transnational Protests in Europe

Figure 2Common macroeconomic factors (oil prices and interest rates) provide the underlying fuel, social media offers a replicable form of protest, and fiscal and political vacuums leave society without a safety net.

Level 1: Common macro-level factors (primary drivers)
The 2011 crisis was triggered by the collapse of sovereign credit in certain southern European countries and had a distinctly country-specific character; by 2026, however, Europe will be facing a highly homogeneous form of ‘import-driven energy inflation’. The price premiums resulting from disruptions to crude oil and liquefied natural gas supplies caused by blockades of the Strait of Hormuz have fallen almost indiscriminately on every household in the eurozone. This shared financial burden explains why several countries reacted in unison in mid-October.
Level Two: The transnational replication of forms of protest (social media as a catalyst)
The protests across different countries have been remarkably uniform in form: student walkouts, blocking ring roads, setting fire to roadblocks, and guerrilla-style confrontations with riot police. Driven by algorithmic recommendations and short-form videos, the protest tactics and slogans of one city can be adopted by young people in neighbouring countries within 48 hours. Social media has not only reduced the information costs of transnational mobilisation but also provided psychological support in the form of the reassurance that ‘protests elsewhere have already been recognised’.
Third layer: Political vacuum and depletion of fiscal space (amplifier)
France is undergoing a period of political realignment towards the end of Macron’s term, with the traditional establishment’s grip on power waning; several southern European countries are also hampered by fragile coalition governments. Unlike in 2011, government bond yields in major countries are now very high, and governments are unable to ‘buy stability’ by issuing large-scale bonds to fund full energy subsidies. Lacking the resources for compromise and fearful that heavy-handed suppression might trigger a political backlash, the standoff on the streets has thus reached an impasse.

Note: This article concludes that the current wave of protests is ‘primarily driven by common causes, with cross-border transmission playing a secondary role’. If the spread were primarily driven by social media, the time lag between outbreaks in different countries would typically be eliminated within a matter of days; however, this round of protests has unfolded in waves since 17 October, closely aligned with the timing of CPI data releases and the start of the heating season in various countries.

III. The Politicisation of the Housing Crisis: Spain

Spain is a prime example for observing ‘how the rising cost of living translates into issues of social class’:

The combined pressure of rising prices and rents: Spain’s CPI for September stood at 4.9 per cent, the highest of the five countries surveyed; the housing and utilities sub-index rose year-on-year 7.2%, with diesel prices rising year-on-year 30.3%。
The conflict between the commercialisation of tourism and the housing shortage: In August 2026, Spain welcomed a record number of international visitors, whilst short-term holiday rentals (such as Airbnb) in cities including Barcelona and Madrid continued to crowd out long-term rental properties. Tenants’ rights organisations have successfully elevated the issue of ‘unaffordable rent’ from a personal financial hardship to a social movement opposing gentrification and the institutional capital monopoly on housing.
As data on the house price-to-income ratio and the monthly rent index at EU level are not directly available, this section provides only a qualitative overview and does not include any unverified figures.

IV. Student Protests and Generational Squeeze: France

Young students have become the driving force behind this round of protests, and the factors behind this are directly linked to the underlying structure of inflation:

The billing structure is most disadvantageous to young people: This round of inflation has been driven primarily by energy (France: +21.3 per cent), transport (Spain: +10.5 per cent) and rent, whilst core inflation (France: just 1.5 per cent) has remained subdued. The younger generation, who have no assets to their name and lack tools to protect against inflation, see the majority of their expenditure concentrated on essential costs such as commuting, shared utility bills and cheap takeaway meals; as a result, they are far more severely affected than middle-aged and older people who own property.
Decentralised methods of mobilisation: Compared with the ‘May 1968’ protests or the 2006 campaign against the First Employment Contract (CPE), these student demonstrations represent a decentralised, ‘network-based’ mobilisation, with no coordination by traditional trade union leaders. The government is facing a governance impasse with no clear negotiating counterpart, and the imposition of a partial curfew in Paris also reflects the diminishing effectiveness of traditional law-and-order measures.

V. The Double Squeeze of Energy Bills and Interest Rates

This section explains the following:The energy crisis and central bank interest rate rises are putting pressure on the European real economy from two directions simultaneously.

5.1 Input-side energy shocks

The eurozone’s energy sub-index rose year-on-year 18.9%, with the energy sub-index in France reaching as high as 21.3%. Europe’s structural vulnerability, stemming from its heavy reliance on fossil fuel imports, has once again been laid bare against the backdrop of turmoil in the Middle East. The blockage of the Strait of Hormuz has now lasted for approximately seven months; although crude oil shipping volumes have partially resumed, shortages of refined petroleum products (particularly diesel and jet fuel) remain severe, directly driving up diesel prices in Spain by 30.3 per cent and petroleum product prices in France by 36.2 per cent.

Key price movements and timeline of geopolitical events for Brent crude oil in the second half of 2026

Figure 3With the Strait of Hormuz blocked for around seven months, shortages of refined oil products such as diesel have continued to drive up inflation in Europe.

5.2 Three channels through which the ECB’s interest rate rises are transmitted

According to the European Central Bank’s Monetary Policy Interest Rate Statistics (ECB MIR, published on 2 September 2026, covering July data) and financial market data, the policy rate (deposit facility rate of 2.50 per cent) is being transmitted to the real economy along three main channels:

Conduction pathways	Interest rate levels	Transmission mechanisms and impacts	Data sources
Base policy rate	2.50%(Interest rates on deposit facilities)	On 10 September, interest rates were raised by 25 basis points to tighten overall liquidity; the market still expects a further rate rise in December	European Central Bank Interest Rate Decision
Channel 1: Newly granted mortgages	3.54%	Increasing the monthly mortgage repayments for new-build properties and the repayment burden of existing variable-rate mortgages is exacerbating the housing affordability crisis	ECB Banking Interest Rate Statistics (July data)
Channel 2: Loans to non-financial enterprises	3.80%	Increasing the cost of financing for companies’ working capital and investments, thereby limiting scope for pay rises	ECB Banking Interest Rate Statistics (July data)
Channel 3: Micro-enterprises and sole traders	4.29%	Self-employed individuals and micro and small enterprises bear the highest risk premium and have the weakest buffers	ECB Banking Interest Rate Statistics (July data)
Government debt servicing	a near 24-year high	With yields on 10-year French government bonds remaining high and the budget deficit widening, the Treasury is finding it difficult to provide large-scale funding for a comprehensive price-cap subsidy scheme.	Benchmark yields on the French government bond market

Figure 4The policy interest rate rose to 2.50 per cent, driving up mortgage rates (3.54 per cent) and small business loan rates (4.29 per cent) across the board.

5.3 Monetary Policy Mismatch and the Stagflation Dilemma

Interest rate rises fail to curb sea freight rates and tanker war risk premiums (Brent crude, 20 October) US$110.48). In the face of a supply shock, monetary policy can only curb demand; it cannot increase supply. I wrote inFederal Reserve Interest Rate Hikes and Oil PricesThe ‘failure of policy instruments in the face of supply shocks’ discussed in the article also holds true in Europe, where dependence on energy imports is even higher, making the situation there even more precarious.

VI. Austerity Pressures and Political Capitalisation (Outlook)

The ‘Austerity 2.0’ standoff with the trade unions: As the European Union has re-tightened the deficit thresholds under the Stability and Growth Pact (with Austria’s budget deficit, for example, already exceeding 4 per cent of GDP), countries face strict constraints when drawing up their budgets this winter, forcing them to cut education spending and postpone pay rises in the public sector. The winter protests by trade unions and public-sector employees are likely to converge with student demonstrations.
The political gains of the far right and populist forces: Experience in Europe suggests that the social anger fuelled by street protests typically translates into votes after 6–12 months. Far-right opposition parties are exploiting the cost-of-living crisis and anti-austerity sentiment to attack the establishment government. As opinion polls remain volatile, this article offers only a tracking outlook and refrains from drawing political conclusions.

VII. Scenario Analysis and Forward-Looking Indicators

Note: The probabilities are analytical estimates based on macroeconomic variables and political constraints; they are not definitive forecasts.

Scenario	Pathways to Development	Probability	Trigger conditions	Market and Social Implications
A: Base-case scenario	Intermittent and persistent during winter	Approximately 50 per cent	Brent crude is fluctuating within the $100–$110 range; The ECB raised interest rates by 25 basis points in December, but its statement adopted a wait-and-see stance; France and Spain have only introduced small-scale, targeted relief measures, with no large-scale, universal subsidies; The demonstrations did not escalate into an indefinite, cross-sector strike	The protests have developed into regular weekend demonstrations, causing localised disturbances; The current government is under pressure, but is unlikely to collapse in the short term; The euro and European sovereign debt continue to trade at a moderate political risk discount
B: Worsening circumstances	Escalation of protests and transnational spread	Approximately 25 per cent	The Strait of Hormuz has once again been subject to an armed blockade, with oil prices soaring to over $115; Confrontations between the police and the public in key cities have escalated, resulting in serious casualties; Joint strike by transport, energy and school trade unions; The austerity budget was rammed through Parliament, fuelling a backlash	The protests have spread to more countries in Central and Northern Europe; France faces a crisis over a vote of no confidence in the government or early general elections; European bond spreads widened involuntarily, causing European share markets to fall
C: Mitigating circumstances	Geopolitical Tensions Easing and Gradually Abating	Approximately 25 per cent	A ceasefire framework has been agreed in the Middle East, and oil prices have fallen back below US$90; Demand for heating peaks in the latter half of winter, and the base effect in energy prices causes inflation to ease; The government has allocated special funds to provide rent subsidies to young people and tenants; The ECB’s December decision sent a clear signal of a pause	As the bitter cold and the cost-of-living crisis eased, the street protests naturally subsided; The political crisis has been temporarily resolved; Public sentiment is shifting towards the next election cycle

Three Possible Scenarios for the Evolution of the Wave of Protests in Europe and Key Indicators to Monitor

Figure 5The baseline scenario (50 per cent) is that the protests will evolve into intermittent demonstrations that become a regular feature of weekends during the winter; key factors to watch are the trend in oil prices, the ECB’s December monetary policy guidance and the negotiations over the French budget.

Tracking and Falsification Checklist

When assessing the direction of the wave of protests, the three most telling indicators are:

International oil prices: If Brent crude falls back below US$90, the energy-import-driven logic will rapidly weaken, and the probability of Scenario C will rise significantly; if it breaks through US$115, the risk associated with Scenario B will surge.
ECB December decision: If the ECB were to pause its rate rises under pressure from stagflation and adopt a neutral stance, expectations of a further tightening of financial conditions would cool significantly.
Budget deliberations in the French National Assembly: Keep an eye on the vote on public expenditure and energy taxes in the 2027 Budget. If the government invokes constitutional provisions to force the bill through, leading to the collapse of the Cabinet, the political crisis will rapidly spill over into the economy.
