The European Securities and Markets Authority will receive a 17% budget increase this year but some industry watchers warn it may not be enough for the regulator to fulfil its ever-increasing duties.

A document on Esma's website lays out a budget of €33.2 million for 2014, an increase from the €28.2 million it received in 2013. Just over 45% of this year's total will come from national regulators and a third will come from the European Union.
