Polish bond yields were unmoved as markets were looking forward to the central bank's schedule of June bond purchases, due later in the day.
Currencies kept hovering near strong levels they recently hit on rate hike expectations that were fuelled by higher-than-expected CPI data and signals from central banks.
The Polish zloty slid 0.17% to 4.5300 versus the common currency after firming in the previous session on increased rate hike prospects in the CEE region.
Central European rate-setters are facing rising inflation, but look set to keep rates low for the time being to help their economies recover from the effects of the coronavirus.
"This picture, however, cracked somewhat with the GDP result for the first quarter released last week, which showed the economy did better than thought."
The Hungarian forint slid 0.42% to 360.80 per euro, underperforming its peers. It has lost 1% this week.
The currency weakened in low liquidity because of a zloty-forint flow, traders in Budapest said, adding that the forint was also due for a correction after steady gains in the past few weeks.
The Polish zloty was 0.54% firmer against the euro at 4.5516, the Czech crown had strengthened 0.09% to 25.8210, while the Hungarian forint was 0.13% stronger at 358.70.
"Over the next few days, the yields of 2-year bonds should remain around 0.05%, while the yields of 10-year bonds should remain close to 1.60%," PKO BP analysts said in a note.

The zloty was 0.17% firmer against the euro at 4.624. The Czech crown was 0.12% firmer at 26.08 and the Hungarian forint was little changed at 362.10.
"Today, a positive reception of the ECB's decision by the euro may indirectly support the zloty and the currencies of the region," Konrad Bialas, chief economist at DM TMS Brokers said in a note.

The Hungarian forint slid 0.43pc and was trading at 358.50 per euro as markets waiting for developments regarding the European Union's budget and coronavirus rescue package.
Stock markets were mixed, with Budapest's main BUX index jumping by 2.3% and Prague rising 0.4%. Shares in Hungarian OTP Bank extended its gains from Tuesday, rising 1.3%.
Warsaw's main index, however, fell by almost 2%, which some analysts said was caused by concern about the record numbers of Covid cases and profit taking by some players.
