Expectations that Hungary could cut interest rates further are rising.
Hungary's central bank, in line with an expansion of its toolkit announced in April, extended cheap financing on Thursday at its first 3- and 5-year interest rate swap tender and demand surged for 5-year bonds at an auction the same day, knocking down yields and fuelling expectations for more interest rate cuts.

"For the time being, this reading is one more which will boost MPC (central bank) dovishness, she said, adding that the bank could cut rates by 50 basis points by September.
The zloty, which firmed after the confidence vote, eased slightly against the euro on Friday.
Central European equities regained some ground, led by a 0.7 percent rise in Budapest's main index, after a fall earlier this week in tandem with developed markets.
