Santander UK’s 8% savings offer intensifies retail banking competition as UK customers switch banks at a rate of one million per year

Likely next: Rival banks may respond with comparable or promotional savings offers; regulators may monitor the market for unfair practices; Santander will likely assess uptake and adjust pricing accordingly.
