BUDAPEST (Reuters) - Hungary's government has extended a cap on some basic food and fuel prices until 1 October 2022, while a cap on retail mortgage interest rates will remain in place until the end of the year, Prime Minister Viktor Orban said on his Facebook page on Thursday 16 June 2022.

Inflation across Eastern Europe has surged since Russia's invasion of neighbouring Ukraine amplified already strong price pressures following the coronavirus pandemic, forcing central banks across the region into sharp interest rate hikes.

Prime Minister Orban's price caps have been a mainstay of efforts by his nationalist government to shield households from the higher cost of living, but even with these measures, inflation rose into double-digit territory last month.

The short announcement on Prime Minister Orban's Facebook page did not contain further detail, likely indicating that the measures would be extended in their current form.

The National Bank of Hungary, already in its third-steepest rate hike cycle since the collapse of communism, was forced to raise its one-week deposit rate further on Thursday to shore up the forint, which fell to a record low versus the euro this week.

So far there is little evidence that the bank's rate rises have meaningfully curbed inflation, which could exceed the NBH's 9.8% forecast for the full year issued in March, Deputy Governor Barnabas Virag told reporters earlier in the day.

Prime Minister Orban's government set a 480 forint ($1.25) per litre limit on fuel prices in mid-November and followed up with caps on some food staples in February. The measures have lopped five to six percentage points off headline inflation, Prime Minister Orban has said.

The scope of the fuel price cap was recently narrowed to cars with a Hungarian licence plate, triggering conflict with the European Union, while Hungarian energy group MOL has called for the gradual phasing out of the measure.

The extension of a cap on mortgage rates to shield borrowers from the higher cost of borrowing will be an additional hit to banks in Hungary, already slapped with a big windfall tax as part of Orban's measures to cut the budget deficit.

At 1201 GMT, MOL shares traded 2.3% lower at 2,832 forints on the Budapest Stock Exchange, underperforming the blue chip index, which fell 1%. Shares in Hungary's OTP Bank fell 0.4%. ($1 = 383.3 forints)
