The beat was underpinned by much lower-than-expected "cost of risk" - money set aside for failing loans - of 166 million euros.
Analysts had expected 430 million euros.
Dubbed a "year of transition" by Krupa's predecessor Frederic Oudea, 2023 is also marked by a severe downturn at SocGen's French retail banking division, fresh from a merger of its two local networks.
The second quarter was also affected by negative exceptional items of 240 million euros, which Credit Suisse analysts said were tied to "legacy legal disputes".
Retail banking outside France fared better, as did SocGen's car leasing division ALD Automotive (ALDA.PA), whose sales jumped by more than 17% thanks to the acquisition of rival LeasePlan.
