Two shocks, one summer

Construction

Crude makes the round trip. Works indices do not.

Why civil-works materials are down 2.5 % year-on-year while the cost of public works is up 7.4 %.

Summer 2026 makes one gap impossible to ignore. On one side, materials are calming down: the cost index for civil-engineering materials is down 2.5 % year-on-year in March 2026 (ICM-42 index, INSEE), and building materials are up just 1.6 % (ICM-412 index). On the other, works cost indices are accelerating: the general public-works index reaches 140.4 in May 2026, up 7.4 % year-on-year (TP01 index, INSEE), asphalt production is up 13.4 % (TP09 index) and energy networks 7.5 % (TP12a index). Building follows more calmly, at +3.8 % for the all-trades index (BT01 index, 137.9 in May) and +5.7 % for electrical works (BT47 index). In other words: it is no longer the price of the material that drives the bill, it is the energy that transforms it, the bitumen that binds it and the labour that lays it. Crude returning to 101 dollars in late July will only feed that mechanism. On volumes, residential is holding: 365,500 housing units authorized over twelve rolling months to end-June 2026, up 10.0 % year-on-year (source: SITADEL / SDES). But non-residential is down 13.3 % and land development down 15.4 %, which will weigh on earthworks and roadworks activity in twelve to twenty-four months.

🔍 Focus: why a works index never comes down as fast as it went up

A works cost index is not a market price, it is a weighted average of several components: materials, energy, plant, transport and wages. When crude climbs, it hits the energy and transport components first, immediately. When it falls back, those two ease, but wages and plant do not: a negotiated pay rise cannot be un-negotiated, plant depreciation cannot be rewound. Economists call this a ratchet effect. In practice, over twelve months, the gap between the general public-works index (+7.4 %) and the civil-engineering materials index (-2.5 %) approaches ten points: that gap is precisely the share of the bill that will not travel backwards, even if oil returns to 70 dollars this autumn. For any organisation signing fixed-price contracts, the consequence is direct: indexing on a materials index protects less and less, because that is no longer where the increase happens.

Copper (COMEX futures): about $14,297/t in July 2026, up 4.7 % on the month. Late June's pullback, around $13,500/t, therefore lasted only a few weeks.
Aluminium: about $3,340/t in July 2026, down 2.8 % on the month. The only major construction metal that did not turn back up with crude.
Why the gap matters: the asphalt index (TP09) is up 13.4 % year-on-year while civil-engineering materials are down 2.5 %. Bitumen, a direct refining by-product, is the channel through which the crude price enters roadworks contracts.

⚠️ Two watch points for the autumn. First, crude: at 90 dollars on 31 July, it remains above the level that triggered the spring alert, and any renewed escalation will show up in asphalt and network indices with a six to nine-month lag. Second, the most recent SITADEL months remain provisional: an isolated very low month there is almost always an incomplete month, not a genuine drop.

Real estate

Long rates never made the return trip.

Crude moved 40 % in eight weeks. The French 10-year government bond moved six hundredths of a point.

The contrast is striking. While oil collapsed then rebounded by 40 %, the yield on the French 10-year government bond, the OAT, barely moved: 3.73 % in April, 3.74 % in May, 3.68 % in June 2026 (source: Eurostat, Maastricht convergence criterion). It stood at 3.53 % in January. In other words, spring's disinflation and the return of the energy shock cancelled each other out from the standpoint of long rates, which remain parked at the top of their range. Yet it is the OAT, not current inflation, that sets the floor for mortgage rates. The latest public data point for housing credit is the average rate on new loans at end-2025, at 2.98 % (source: Banque de France): the sub-3 % window that fuelled the market rebound opened then, and nothing in long rates suggests it will reopen. On the market side, the most recent public data confirm an exit from the downturn without euphoria: the price index for existing flats stands at 126.7 in the fourth quarter of 2025, houses at 127.8, and existing-home transactions at 951,000 over twelve rolling months (source: Notaires-INSEE index and Notaires de France). New-build remains the weak link, at 15,536 developer sales over the quarter (source: SDES).

🔍 Focus: what really sets the price of your loan

Many buyers reason this way: inflation is falling, so credit will fall. That is wrong, and summer 2026 proves it. A mortgage rate is built from three blocks. The first is the European Central Bank policy rate, raised to 2.25 % on 17 June after a 25 basis-point hike decided on 11 June, the first in three years. The second is the 10-year government bond yield, which embeds the health of public finances: French public debt reached 117.6 % of gross domestic product in the first quarter of 2026 (source: Eurostat), against 64.4 % in Germany. That gap is what sustains a lasting risk premium on the OAT. The third is the banks' commercial margin, which rebuilds as lending picks up. On these three blocks, current inflation acts only indirectly, and with considerable lag. Practical conclusion for a buyer: the window near 3 % is a cycle low, not a step toward something lower. Locking it in beats waiting for it.

10-year OAT (the benchmark French government bond): 3.68 % in June 2026, after 3.74 % in May and 3.53 % in January (source: Eurostat, Maastricht convergence rate).
French public debt: 117.6 % of gross domestic product in the first quarter of 2026, against 109.1 % in Belgium, 101.6 % in Spain and 64.4 % in Germany (source: Eurostat).
Why the pair matters: the gap between the French and German bond yields, the latter at 2.96 % in June, directly measures what public debt costs the French home buyer, on top of the general level of rates.

⚠️ The prices and volumes published by notaries cover the fourth quarter of 2025: that is the normal publication rhythm for this statistic, not a delay. So be cautious before drawing any conclusion about summer 2026 from these figures. The real signal to watch into the autumn remains the OAT: it will decide whether the credit window closes slowly or abruptly.

Transport

Volumes are holding. Morale is not.

Every mode is growing, service prices are up 4.3 %, and yet road hauliers have never been so pessimistic.

On volumes, French transport has no problem. Air freight reached 199.7 thousand tonnes in February 2026, up 13.0 % year-on-year, of which 177.3 thousand tonnes through Paris airports alone, up 13.9 % (source: SDES and the French civil aviation authority). Rail freight stood at 2,885 million tonne-kilometres in December 2025, up 4.2 %, driven by international traffic at +5.8 %. Inland waterways are up 10.7 %, at 490 million tonne-kilometres. Even heavy-goods traffic on motorways, the most direct barometer of merchandise activity, is not receding: 1.27 billion vehicle-kilometres in December 2025, up a slight 0.6 %. And yet hauliers report an opinion balance of -13.7 points on demand trends and -22.3 points on their activity outlook (source: INSEE, business survey in road freight transport, March 2026). This gap between volumes that hold and morale that slips has a simple explanation: margin. Prices for freight transport services are up 4.3 % year-on-year in June 2026 (source: INSEE, consumer price index), which looks comfortable until you add driver costs, tolls, fleet renewal investment and, since late July, diesel once again pulled by crude at 90 dollars.

🔍 Focus: why transport absorbs the oil shock before anyone else

In most sectors, a rise in crude takes months to show. In transport, it shows in days. Diesel accounts for a quarter to a third of the cost per road kilometre, kerosene even more for air freight, and marine bunker fuel tracks crude almost immediately. When Brent goes from 84 dollars on 16 July to 100.69 on the 23rd, a haulier's energy bill moves within the same week, while their customer contracts were often signed in the spring. That scissor effect is precisely what explains the current paradox: volumes up everywhere, service prices up 4.3 %, and yet an opinion balance of -22.3 points on the outlook. In this context, the diesel indexation clause is less a contractual detail than a survival device. Without it, every round trip of crude is paid out of the carrier's margin, never the shipper's.

Brent (ICE Futures): $84.23 on 16 July, $100.69 on 23 July, $90.20 on 31 July 2026. A 16-dollar swing in one week, the equivalent of a full year of normal drift.
Freight transport service prices (INSEE): +4.3 % year-on-year in June 2026. Carriers are passing costs through, but with a lag behind fuel.
Why the pair matters: when fuel moves faster than service prices, the difference comes out of the margin. That is what the -22.3-point opinion balance on the road-freight activity outlook measures, in reverse.

⚠️ The Strait of Hormuz stayed open throughout July's escalation, and that is the main reason crude fell back to 90 dollars. It is also the fragility of the autumn: roughly a fifth of the world's oil transits there. A closure, even brief, would not show in French freight volumes for several weeks, but in the diesel price the very next day.

Inflation is low. So is the room for manoeuvre.

France posts the best inflation in its neighbourhood and the least vigorous growth. What that says about the autumn.

On paper, France has won the inflation battle: the consumer price index is up 1.8 % year-on-year in June 2026 (source: INSEE, provisional estimate), while the euro area harmonised index remains at 2.8 % (source: Eurostat, flash estimate). That is the best position in its immediate neighbourhood. The problem is that this victory comes with two handicaps. The first is growth: French gross domestic product is up 0.7 % year-on-year in the second quarter of 2026, against 0.9 % in Germany, 0.5 % in Belgium and 2.7 % in Spain, now clearly ahead (source: Eurostat). The second is employment: the French unemployment rate stands at 8.2 % in June 2026, stable since April, against 3.9 % in Germany and 6.3 % in Belgium, with Spain still higher at 10.1 % (source: Eurostat). Add a monetary policy that has just tightened at the worst moment, and the picture reads as follows: France enters the autumn with prices under control, subdued demand and no easing to expect. The European business climate does give a mildly encouraging signal: the French economic sentiment indicator rises to 95.9 in July 2026, after 93.5 in June (source: European Commission and Eurostat). It is small, but it is the first pick-up since the spring.

🔍 Focus: France produces more than Germany, and grows more slowly. How?

Here is a figure that consistently surprises. The manufacturing production index, base 100 for 2021, reaches 104.6 in France in May 2026, almost level with Spain at 104.7, and far above Germany at 92.6 (source: Eurostat). In other words, German industry today produces 7 % less than in 2021, while French industry produces nearly 5 % more. That still does not make France the region's locomotive: its growth remains at 0.7 %, against 2.7 % in Spain. The explanation lies in the relative weight of the engines. Germany depends on an exporting industry hurt by the global slowdown and energy costs. Spain benefits from a rebound in tourism, construction and favourable demographics. France has an industry that holds up but a domestic consumption engine slowed by 8.2 % unemployment and high precautionary saving. The takeaway for anyone selling in Europe: the country ranking by inflation and the ranking by growth no longer resemble each other at all, and Spain is now the most dynamic of the four markets.

📈 Market indicators, Economy

European Central Bank deposit rate: 2.25 % since 17 June 2026, after a 25 basis-point hike decided on 11 June, the first in three years.
Economic sentiment indicator (European Commission): 95.9 in France in July 2026, against 104.3 in Spain, 92.7 in Germany and 88.8 in Belgium.
Why the pair matters: a central bank that has just tightened, plus business sentiment still below its long-run average, means neither of the two usual stimulus levers will play before 2027.

⚠️ The July inflation figure, published in mid-August, will be the first to include late July's crude rebound. It will give the true measure of what the Iranian escalation cost purchasing power. Also worth watching: household confidence, at 86 in July 2026 according to INSEE, still 14 points below its long-run average.
