Markets have turned glum again as October gets underway and the northern winter looms, weighed down by a relentless grind of negative commentary even if there’s been little really new information to digest. The net loss on MSCI’s world stock market index over the past seven days is a fairly restrained 1.5%, though we are now back down to early September levels. Debt markets have been better behaved. The likes of Spain’s 10-year yields are virtually unchanged over the past week amid all the rolling huff and puff from euroland. The official argument that Spain doesn’t need a bailout at these yield levels is backed up by analysis that shows even at the peak of the latest crisis in July average Spanish sovereign borrowing costs were still lower than pre-crisis days of 2006. But with ratings downgrades still in the mix, it looks like a bit of a cat-and-mouse game for some time yet. Ten-year US Treasury yields, meantime, have nudged back higher again after the strong September US employment report and are hardly a sign of suddenly cratering world growth. What’s more, oil’s back up above $115 per barrel, with the broader CRB commodities index actually up over the past week. This contains no good news for the world, but if there are genuinely new worries about aggregate world demand, then not everyone in the commodity world has been let in on the ‘secret’ yet.
