Stocks retreated once again on Friday, following another session of convulsions in global capital markets. Quite poignantly, on Friday one US policy maker - the President of the Federal Reserve bank of St.Louis - criticised Ben Bernanke´s poor timing regarding the announcement of a detailed plan for reducing the pace of asset purchases. Perhaps the best proof of the magnitude of the fallout from Wedesday´s US Federal Reserve meeting is the enormous rise seen in China´s one-day repurchase rate (the interest rate at which banks lend to each other in that market) on Thursday, as lenders underwent a 'cash squeeze.' Today it fell back again, by 3.84 percentage points, to 7.90%, after the central bank injected liquidity overnight, but it is sure to have raised some eyebrows amongst market participants. In that same vein, and closer to these shores, US 10 year Treasury yields moved higher again this afternoon, reaching an intradday high of 2.51%. Those yields are a key determinant of many economic decisions and are thus closely followed by markets. Not by coincidence, the benchmark 10-year Gilt yield rose 12 basis points to 2.42% in afternoon trading. Be that as it may, experts think that low summer-induced trading volumes may be a factor behind the recent move higher.Thus, and queried as to whether that was a real possibility, Bill Hubard, Chief Economist at Markets.com, had this to say: "YES...you are also witnessing 'certain' accounts who DID not take profits at/around 2.00%-2.125% taking profits and now waiting for 2.375%-2.42% to re-purchase as I feel (as do a number of major accounts!!) that we will see 1.75%-1.875% before we see 2.50% in the next 3 months."As if all of the above were not enough, and feeding some of the market´s apprehension, the smallest party in Greece's ruling coalition - Democratic Left - haspulled out of the government over a row regarding the closure of state broadcaster ERT.
