Sparen: DKB-Tagesgeld im Check: Sind die vier Prozent wirklich spitze?

Deutschland's second-largest direct bank, DKB, has joined the ranks of top providers offering a four-percent interest rate on Tagesgeld accounts starting November 1st. Financial expert Oliver Maier predicts this interest rally will enter a new phase. DKB faces competition from new entrants aggressively targeting the German market.

The bank's move could put pressure on other major banks to engage in a fierce customer acquisition battle. While high-yield seekers should view this as a positive sign, they should be aware of the conditions attached to most offers, which can be costly. DKB currently provides four percent interest on deposits up to 100,000 euros.

To participate, customers must transfer funds from another bank to a DKB Tagesgeld account before October 20th. The bank's offer is aimed at attracting existing customers rather than new ones. To qualify, customers must maintain a monthly average balance of 700 euros in a DKB Girokonto, or face monthly fees of 4.50 euros. Revolut offers a slightly higher rate of 4.25 percent but requires a monthly transaction of at least five euros.

Estnian Bigbank, Ayvens Bank, Openbank in Spain, and Chase in Germany all offer 4.15 percent, but require a Girokonto or deposit. Consorsbank guarantees 3.8 percent for five months, while Suresse Direktbank in Spain offers 3.7 percent for six months. Experts advise investors to consider inflation, as interest rates below 3.3 percent currently result in real losses.
