By Anita Komuves BUDAPEST, Nov 16 (Reuters) - The forint weakened on Monday as the Hungarian government said it was ready to veto the European Union's budget and COVID-recovery fund, while other Central European currencies were stable and regional stock markets firmed. Government spokesman Zoltan Kovacs told Reuters that Hungary will veto the EU's 2021-2027 budget and post-COVID recovery fund unless its fellow member states revise a clause to tie disbursement of EU funds to rule of law conditions. Polish Prime Minister Mateusz Morawiecki sent a letter to EU institutions last week containing a similar threat. "The upcoming vote on the EU budget is causing tension in the market. The threat of the Hungarian veto plays a role in the weakening of the forint," a Budapest-based FX-trader said. "It is going to affect the zloty as well, but Hungary is smaller and thus more vulnerable to these pieces of news." The forint was 0.54% weaker by 1027 GMT, trading at 358.55 per euro and underperforming its peers. The Polish zloty was up 0.23% and trading at 4.4810 versus the common currency. The Czech crown edged up 0.02% to 26.4300 per euro. "Regional currencies appreciated strongly in the previous two weeks, so further appreciation, amid the ongoing COVID-19 pandemic, would be difficult to achieve," Erste Bank wrote. Markets are also eyeing the National Bank of Hungary's rate-setting meeting on Tuesday. Accoring to a Reuters poll of analysts the bank is expected to leave its base rate at 0.6% as a retreat in inflation and gains in the forint ease pressure on the bank. Most stock markets in the region firmed against a global risk-on backdrop, with Warsaw up 1.68%, and Budapest and Bucharest both edging up 0.05%. Prague's blue chip index rose 1.2%, with telecoms group O2 adding 3% after the regulator announced late on Friday that it and two other incumbent mobile operators had won frequencies in an auction connected to future next-generation 5G networks.
