Two years ago HFSF named an Austrian, Martin Czurda, as its chief executive. That choice rankled Greek bankers and politicians. But it was demanded by euro zone institutions involved in the country's bailout, including the European Central Bank and the European Stability Mechanism. The fund needed someone to put pressure on the banks who was free of any conflicts of interest that might inhibit a former or future member of the local financial industry.

The fruits of that decision were on display again at NBG's annual meeting on Wednesday. Shareholders approved expanding the board of the 2.4 billion euro bank to include two new independent non-executive directors. One, former Finance Minister Gikas Hardouvelis, will serve in a senior capacity.

The revamp was the result of a campaign by Czurda's team as well as Velos Advisory, an external governance consultant. Though it met with resistance from NBG's chairman and others, it received a positive reception from international investors. The bank's stock has more than doubled this year.

The new government hasn't yet publicly sought a changing of the guard at HFSF. However, the idea of putting a Greek in charge cropped up during the recent election campaign and is popular in the banking community. Another suggestion would see the fund tucked into the Hellenic Corporation of Assets and Participations, a holding company for state-owned assets, diluting HFSF's independence.

Either move could provoke a potentially distracting fight with constituents like the ECB. It would also detract from the work the fund is doing, alongside the Bank of Greece, to reduce dud loans which still account for 45% of all bank credits. And it would remind investors of Greece's previous Syriza government, which in 2016 pressured the CEO of Piraeus Bank to resign against the wishes of shareholders.

Czurda's mandate expires in June 2020, a little more than two years before the fund itself can be wound down. To avoid scoring an own goal, Mitsotakis should bide his time.
