PRAGUE, Feb 23 (Reuters) - Stress tests showed the Czech banking system will maintain sufficient capital adequacy in all projected scenarios, the central bank said on Tuesday.
Czech banks have avoided losses in the global financial markets crisis thanks to a high level of domestic savings, small holdings of toxic assets and a small proportion of lending in foreign currencies.
But the economic downturn hit banks' balance sheets, reversing years of double-digit profit growth.
They now face rising costs from provisioning for bad loans, which banks expect to peak later this year.
"Banks survived the crisis in a good shape, the results were very solid, therefore they are in a good condition for the years ahead," Jan Frait, deputy chief of the central bank's economic research and financial stability department, told a news conference.
Risks to overall financial stability will remain high but the banking sector was seen to be able to resist all potential unfavourable shocks, the tests showed.
Aggregate capital adequacy will remain above the regulatory 8 percent minimum in all three projected scenarios, although several banks may face the need to slightly raise capital in the two more pessimistic scenarios out of three.
The most pessimistic scenario however saw the need to hike capital in the banking system by just 13 billion crowns ($691.5 million).
The overall capital adequacy of the banking system was around 13 percent at the end of 2009, high above the regulatory minimum of 8 percent.
The baseline scenario is based on the bank's staff forecast, assuming GDP growing by 1.4 pct this year.
The most pessimistic one, called "loss of confidence", assumes a steep rise in money market rates and bond yields, and a currency weakening.
COST OF RISK ON THE UPSIDE
Almost all Czech banks are foreign-owned, with the three largest -- CSOB, Ceska Sporitelna and Komercni Banka <
> -- owned by Belgium's KBC <KBC.BR>, Austria's Erste Group <ERST.VI> and Societe Generale <SOGN.PA>, respectively.The rising cost of risk along with sluggish growth in income proved to be the main burden for 2009 performance of Komercni Banka and CSOB which have already reported results.
The baseline projection saw corporate non-performing loans to rise to above 10 percent of all loans from the present level of around 8 percent, Frait said.
Retail non-performing loans should be around 5 percent. The other two scenarios saw the upturn in non-performing loans significantly higher.
CSOB, the Czech Republic's largest bank by assets, saw its non-performing loan portfolio ratio rise to 3.23 percent from 2.18 percent last year. [
