LONDON, Jan 13 (Reuters) - Emerging equities extended losses to a one-week low on Wednesday after Chinese policy tightening and disappointing corporate results soured risk appetite but hopes of a loan deal with the IMF helped Turkey buck the trend.
Prices for oil and metals, the mainstay of many emerging economies, have fallen as investors worry that Beijing's efforts to tighten liquidity -- it raised reserve ratios on Tuesday after raising some t-bill yields -- will dampen commodity and other import demand.
The benchmark emerging equity index <.MSCIEF> fell one percent after losing 0.6 percent on Tuesday. The biggest loser was China, where the Shanghai index fell over 3 percent, with a knock-on effect on many Asian bourses.
"The Chinese tightening is weighing on sentiment plus we also have political noise -- there is talk of (U.S. President Barack) Obama taking $120 billion from the banks and there is going to be congressional testimony on that today," said Knight Libertas analyst Richard Segal.
Obama is expected to announce plans to raise cash from major U.S. banks to cover expected losses from a taxpayer-funded bank bailout as public anger grows over big bank bonuses.[
]The earnings season so far has been lacklustre and market direction is likely to be driven by forthcoming results, including Intel Corp and JPMorgan.
Markets have attempted to consolidate some of the earlier sharp losses, with South Africa's Johannesburg stock index up 0.3 percent and the rand firming half a percent off the two-week lows plumbed in the previous session to the dollar <ZAR=>.
Rand bonds <ZAR157=> however extended losses, with prices dipping to the lowest since Oct 2009 after the first 2010 bond auction drew muted interest.
"The reaction to China's increase in reserve requirements is based on the fact that China is often the most important client for South African exporters of raw materials," said Alvise Marino, emerging markets analyst at IDEAGlobal in Johannesburg.
Analysts say also the rand is due a correction, having rallied over 20 percent to the dollar last year.
Eastern European stocks were marginally weaker though currencies firmed a touch, with the zloty up 0.4 percent to the euro <EURPLN=>, helped by privatisation plans.
The regional winner was Turkey where stocks rallied one percent <
>, though the lira pared most of its early gains, failing to sustain a rise beyond the key technical level of 1.45 per dollar <TRY=>.Markets are eager for a standby deal with the International Monetary Fund (IMF). Prime Minister Tayyip Erdogan however dampened some of these hopes, saying the loan was not indispensable.
MARKETS DIGEST FRESH SUPPLY
Emerging bonds outperformed, with the EMBI Plus index of sovereign bonds <11EMJ> showing yield spreads over U.S. Treasuries tightening 6 basis points to 260 basis points -- around the lowest since June 2008.
Indonesia sold $2 billion in bonds on Tuesday, joining Turkish, Philippine, Polish and Mexican issues and bringing sovereign supply so far this year to almost $11 billion.
Traders said the supply had been well-digested with expectation of more emerging issues on the way.
"Markets are generally tighter across the board though we are keeping an eye on (U.S.) Treasuries," one bond trader in London said, referring to Treasury yields which have risen about 0.4 percent over the past month on the 10-year sector.
"If we see a pronounced (Treasury) sell-off, it will be interesting to see how emerging markets react but there was good appetite for the issues so people still seem attracted to the asset class."
Israel became the latest emerging sovereign to announce eurobond plans, saying it would issue the equivalent of $1 billion this year, possibly in euros [
].Elsewhere on bond markets, Venezuela continued to benefit from last week's currency devaluation, with its portion of the EMBI Plus seeing yield spreads narrow 12 bps to 809 versus Treasuries -- the tightest spread since Sept. 2008.
Markets are awaiting news on Argentina, after a U.S. judge froze accounts held in the United States, a move that may jeopardise or delay plans for a $20 billion debt swap. The news has pushed Argentina's portion of the EMBI Plus to the widest in a month after widening 43 basis points on Tuesday. [
]"The debt swap will go ahead but it will maybe take a month, and we were expecting to have the exchange offer this week," Knight Libertas' Segal said.
