According to the barometer published at the end of August by Infogreffe and the Medef Île-de-France, the Yvelines recorded 8,467 company registrations between January and June 2026, an increase of 9.5% compared to the same period last year. At the same time, deregistrations decreased by 14.9%. Few departments in Île-de-France can show such a combination. The Essonne sees its creations absorbed by the increase in exits. The Hauts-de-Seine are experiencing a nearly 36% increase in deregistrations, the Val-d'Oise 52%. Facing these damaged balances, the 78 department appears to be a diligent student. The contrast is even more pronounced given the darkening national context. In France, more than 306,000 companies have been deregistered in the first half of the year, an increase of nearly a quarter. In Île-de-France, deregistrations have increased by 19.1%. The Yvelines are thus going against the current. Everything changes when moving from rates to volumes. With 10,980 deregistrations, the department has lost about 2,500 more companies than it has seen born. The improvement is real, but it is not enough to reverse the trend. A slowed hemorrhage This is the paradox of the semester. In terms of creation, the Yvelines do not innovate much. Their pace matches exactly the Île-de-France average of 9.5%. Their uniqueness lies on the side of exits. The territory is doing better because it is losing less, and not because it is gaining more. According to Infogreffe, this decline is mainly due to two movements, the net retreat of deregistrations in real estate and those of voluntary deregistrations. Fewer real estate structures have been dissolved. Fewer managers have decided on their own to put the key under the door. A leaking Danaid's vase that leaks less quickly remains a leaking Danaid's vase. The department is filling better, but it is not yet sealing the leak. The failure indicators confirm this nuanced reading. The barometer lists 648 companies in difficulty. Collective procedures have slightly decreased by 2.4%. This overall stability hides, however, a sectoral tension, as the accommodation and catering sector records more openings of procedures. Highly exposed to household purchasing power, this sector remains the weak link. The registered offices provide a more discreet indicator. Over the semester, 258 have left and 161 have arrived. The deficit remains modest. It nevertheless recalls that near Paris and La Défense, the Yvelines' attractiveness for management positions is not self-evident. For a territory that hosts major research centers and important industrial headquarters, from Guyancourt to Vélizy, this trend deserves to be followed. Prevent rather than cure The picture contains a less visible glimmer. At the regional level, the cases of prevention opened before the commercial court have jumped by 38%. In the Yvelines, payment orders are declining significantly. Leaders seem to be seeking help earlier, before unpaid bills accumulate. Perhaps that is where the essential part is played. An economic fabric is not judged only by its birth rate. It is also measured by its ability to treat before burying. With more than 151,000 active companies, the Yvelines have a solid base to achieve this. There remains a question that the semi-annual statistics do not resolve. Does the decline in deregistrations indicate a durable consolidation or simply a temporary reprieve? The second semester will show whether the department has changed course or merely softened its slope.
