* Higher bond yields hit risky assets
* Awaits minutes of Hungary central bank meeting
* Ukraine extends VTB loan tenure

LONDON, Dec 8 (Reuters) - Emerging stocks fell one percent and currencies retreated on Wednesday, as a jump in U.S. and German government debt yields overshadowed rising optimism over economic recovery in the industrialised world.
MSCI's emerging equities index <.MSCIEF> ended five straight sessions of gains, retreating from a 3-/12-week high hit in the previous session and underperforming the broader global equity index <.MIWD00000PUS>.
U.S. tax cuts and the prospect of further monetary stimulus have boosted optimism about economic recovery, although investors remain worried about the euro zone's debt troubles.
Investors booked profits from recent strong gains in emerging equities.
"The rise in bond yields in the developed markets, and particularly in the euro zone, is affecting risk sentiment negatively," said Murat Toprak, emerging markets strategist at HSBC in London.
"We have a slightly negative environment for emerging currencies," he added, noting the rise in the U.S. dollar.
The greenback rose and German 10-year yields topped a six-month high of 3.20 percent following a selloff in U.S. Treasuries on Tuesday.
Asian stocks closed deep in the red but Central European markets <
> fared slightly better, losing around 0.3 percent. Russia was the worst performer, falling one percent as it retreated from 28-month highs hit on Tuesday.Moscow has gained around 10 percent so far this month, boosted by high oil prices, higher-than-consensus corporate results and the European Union's backing for Russia to join the World Trade Organisation.
On currency markets, the Polish zloty led falls in emerging Europe, shedding 0.6 percent to the euro as concerns grew about Poland's budget deficit, expected at around 8 percent of gross domestic product. It was nearly at a two-week low.
While Polish fundamentals are better and debt levels lower than Hungary, many fear it is not doing enough to deal with the deficit problem. Hungary was hit with a two-notch downgrade this week and a Polish rate-setter said negative sentiment could spill over into Poland's bonds as well.
The Hungarian forint <EURHUF=> eased marginally against the euro, ahead of the release of minutes of the central bank's last meeting. [
]A dealer in Budapest said the forint was outperforming because the government had lifted its 2011 GDP growth forecast to over 3 percent and had solved its short-term deficit problem by diverting private pension fund assets into the state budget.
Toprak of HSBC expects the Hungarian central bank to raise interest rates again and said the minutes could possibly shed light on how the bank views the risk environment.
But emerging assets will stay in ranges for now, he said, adding: "Investors are unlikely to take positions into year-end so currencies will ease over in the sessions ahead."
In Ukraine, the government said it is extending by six months the term of a $2 billion loan from Russia's VTB <VTBR.MM>. It took the six-month VTB bridge loan in June to help the government plug holes in the budget.
There was no immediate market reaction.
