Greek lending to households and businesses expanded by an annual 2.8 percent in May, slowing from 3.2 percent in April, the Bank of Greece said yesterday. Lending to households for mortgages and consumer loans remained in negative territory for the second straight month, data from the central bank showed. The money households owed at the end of May fell to 119.35 billion euros, down from 119.45 billion a month earlier. Liquidity pumped into enterprises, however, rose for May. Businesses owed 136.2 billion euros at the end of May, up from 135.2 billion in April.
