Citi: Swedish Diversified Banks: Election Poses Major Risk to Bank Earnings

Citi flags Sweden's September 13 election as a major earnings risk for its banks should the opposition, led by the Social Democrats, take power. The party has championed a 'temporary' tax on banks' net interest income since 2023, projected to raise about SEK 12.6bn under 2026 budget assumptions; allocated by residential mortgage share, it would equal roughly 8–9% of Handelsbanken's 2027 consensus PBT, 6–7% for Swedbank, 3–4% for SEB and 2–3% for Nordea. Polls show the four opposition parties at about 52–54% support (2022: 48.9%) versus 44–46% for the incumbent bloc (2022: 49.6%), with the Social Democrats the largest party at 33–34%. Opposition parties also propose lowering SBAB's ROE target and charging for salary/transaction accounts, further compressing margins. Longer term, two bank taxes within a few years plus share losses to a state-owned challenger could prompt investors to reassess Swedish banks' former safe-haven status and raise their cost of equity. Ratings: Buy Nordea (target EUR 18.60, price EUR 17.62), Neutral SEB (SEK 204 vs SEK 224.4) and Swedbank (SEK 346 vs SEK 376.2), Sell Handelsbanken (SEK 118 vs SEK 147.95). Valuations use dividend discount models based on 2028E sustainable ROEs of 17.4% (Nordea), ~15%, ~15–16% and ~12% respectively, with ~10.4–10.7% costs of equity.
