LONDON, Dec 15 (Reuters) - Hungary's forint tested a six-week trough, while the Czech crown and Polish zloty hit two-week lows against the euro on Tuesday, as news out of Greece and Austria unnerved investors in eastern European markets.
A ratings downgrade of Greece last week, following a restructuring announcement by goverment-owned Dubai World, has increased wariness about sovereign risk.
The issue of western European bank lending in eastern Europe also came back into play, on a report Austria's central bank and its financial market regulator have put Oesterreichische Volksbanken <OTVVp.VI>, the country's top cooperative bank, on a watchlist. [
] However, the bank said the report was inaccurate. [ ]"People are looking at the various fiscal positions in some of these countries, and there is an element of unease coming in," said Zsolt Papp, chief economist, emerging Europe, at KBC.
"The whole willingness and ability of the EU to pay out for member states is being questioned."
Benchmark emerging equities <.MSCIEF> fell 0.33 percent to 975.97.
The forint dropped 0.6 percent <EURHUF=>, testing six-week lows, the Czech crown fell 0.8 percent <EURCZK=> and the Polish zloty fell 0.4 percent <EURPLN=>.
"Tail-risks for emerging Europe remain and suggest that the region will continue to underperform during the recovery," said analysts at RBS in a client note.
The Romanian leu steadied <EURRON=>, however. Romania may get a 1.5 billion euro IMF loan tranche in January, finance minister President Traian Basescu said on Tuesday. [
]Following a $10 billion bail-out of Dubai by Abu Dhabi, Dubai World subsidiary Nakheel said repayment of its $4.1 billion sukuk had reached clearing systems. But investors are still eyeing restructuring plans for a further Dubai World debt pile of more than $20 billion.
"The Dubai saga has seriously damaged investor perceptions of the region," RBS analysts said.
"Investors will need to do more homework to determine stand-alone credit quality and implicit guarantees should not be taken for granted."
The cost of insuring Dubai's debt against restructuring or default was steady in the five-year credit default swaps market, at 430.9 basis points mid-price, according to CDS monitor CMA DataVision.
Emerging sovereign debt spreads overall edged in by 1 bp to 295 bps over U.S. Treasuries <11EMJ>, and remain close to their tightest levels in two months.
Senegal has set the yield on a $200 million five-year bond at 9.25 percent, a banking source said.
Pricing is due later today for the bond, the first in two years from a sub-Saharan African country outside South Africa.
Meanwhile, Seychelles said on Tuesday it launched an exchange offer for a defaulted $230 million Eurobond. [
