This spring's green shoots are being increasing shown to have misplaced optimism, with economic conditions continuing to worsen within the UK - GDP continues to fall, and expectations of a recovery for next year remain muted.

While it's easy to just look at the UK in isolation, there are a couple of major economic pointers on the horizon that suggest the world's economy could suffer major set backs - even before a recovery has begun. And this is likely to bode ill for Britain, with existing downbeat expectations potentially proving to be optimistic if these factors play out.

The first is the credit bubble in China. So far, the Chinese economy has continued to grow strong - but it seems that rather than learn from the mistakes of the West, the Chinese are keen to repeat them. Yes, there's a credit bubble forming in the Chinese economy, as the government there encourages lending to such a degree that the IMF is already alarmed.

The second is the original engine of the credit crunch - the US real estate market. So far it has shown no real recovery, and what's worse, is that not only are repossessions (foreclosures) continuing to increase, they are not expected to peak until after August 2011, when the last big wave of ARMs - subprime mortgages - come up for renewal past their discount period.

These are not the only negative indicators - the IMF continues to warn that the world economy faces a deflationary spiral, that if borne out, could leave much of the West enduring an economic scenario equivalent to Japan's lost decades.

The UK has its own problems as well, not least due to the major debt bubble it's been sitting on for the past few years (it's not simply about house prices anymore). Lending in the UK is still suffering, with a mass withdrawal from the personal loans market, and such poor lending to business by the banks that Alaister Darling is now having to try and appear to be doing something about it. In the meantime, the IMF is warning that the UK's credit card debt could be crippling.

Any suggestion of an improving mortgage market should be taken in context of the fact that Spring and summer are traditionally the peak season - and what we've seen so far is still weak.

In short, economic conditions in the world remain fragile, but there are no positive indicators at present to suggest we're past the worst of it - anything but. There are still major dangers on the horizon, which leave little room for optimism for future economic conditions.
