Deutsche Bank shares plummeted over 14% on early trade on Friday as borrowing costs surged over increased financial risks following the collapse of major banks in the past few weeks, spreading heightened fear over the future of the banking sector, AFP reported.

The stock value of Germany's biggest lender rebounded almost 6 percent on the Frankfurt Stock Exchange, closing at 8.54 euros.

The cost of the bank's debt insurance against default risk fell as investors' trust in the financial sector dropped. The collapse of US' SVB and two other banks, in addition to the chaotic takeover of Credit Suisse by UBS - enforced by the Swiss government - left markets in turmoil.

The impact of Duetche's falling stocks spread to the UK and France, with BNP Paribas and Societe Generale witnessing tumbling stocks during day trade. In attempts to ensure market investors regarding the banking sector, German Chancellor Olaf Scholz said that the lender "modernized and organized the way it works. It's a very profitable bank. There is no reason to be concerned," adding that the EU's banking sector was "stable" and is under strict regulations and rules.

Scholz's remarks came following an EU leader's summit in Brussels on Friday.

In a failing attempt to regain investors' trust in the bank, Deutsche Bank revealed on Friday that it will cash out $1.5 billion in tier 2 bonds before maturity.

This is not Deutsche's first crisis, as the bank was struck with a financial crisis after it attempted to compete with US banking giants pre-2008 crash, which left the bank vulnerable due to the spreading of resources to a market where it failed to compete.

However, the bank, which recorded its highest annual profit last year in 16 years, regained its stable position following deep organizational restructuring, which included slashing thousands of its workforce.

Despite the high impact of rate hikes on the banking sector, further rate rises were announced earlier - leaving the banking sector more vulnerable to money outflow.
