The lack of demand for Italian bank Unicredit's rights offering. The European Banking Authority is requiring European banks to increase their core Tier 1 capital ratios to 9%, to improve the cushion against a financial crisis. Unicredit will have to raise its reserves by $10 billion. Unicredit's shares have fallen sharply in January, with a decline of over 40%. Spain's Santander which has operations in Latin America was able to raise the $19 billion it needed for the higher capital reserves. Santander converted $6.8 billion euros in bonds into shares, retained profits and sold a stake in its Brazilian operations. The risk is that Unicredit and other European banks might cut lending to meet the new capital standards, leading to credit tightening and reducing economic growth further, says Carl Weinberg, chief economist of High Frequency Economics.
