As Iraq appears to be descending into all-out sectarian war, the implications for the oil-dependent economy are huge. Iraq is Opec’s second-largest crude exporter, so markets are already feeling a little jittery, sending crude oil to its highest since September on Friday. Here are five charts showing how Iraq’s economy has developed since the 2003 US-led invasion of Iraq and where its vulnerabilities lie. 

The debt dragon: A monster is rearing its ugly head in China and it is called debt. Whether government, corporate, or even household, it is all on the rise, shooting up from 130 per cent of economic output in 2008, to 200 per cent today.

What would you like to know about China’s debt addiction and its implications for the country and world economy? How did it get so big? Who are the culprits? How much worse could it get? The FT will tackle the Chinese credit habit in a three-part series starting on Tuesday. If you have questions on the subject, simply post them in the comment box below – along with your ft.com name or pseudonym – and I will ask a selection of them to the author of the series Simon Rabinovitch, China correspondent, in a podcast on Wednesday.

Not a milestone to rejoice in. Japan’s debt has tipped into the “quadrillion” zone for the first time. That is, as of the end of June, central government debt, looked like this: Y1,008,628,100,000,000, or $10.4tn.

It surely could not be a clearer message to Japanese Prime Minister Shinzo Abe that shilly-shallying over fiscal consolidation is no longer an option? Second-quarter economic output figures due on Monday are key to Abe’s decision about whether to raise consumption tax from 5 per cent to 10 per cent by 2015. Back in June in a speech in London, he pinned any decision to raise the tax – one he must make by October – on the strength of the economy in the second quarter. 

Hello and welcome to our live blog on the European Central Bank’s press conference. The central bank did what markets expected and kept rates on hold. But ECB president Mario Draghi might offer some clues on what’s to come from the central bank in the months ahead and investors will also be looking for any comments on whether the ECB might start publishing the minutes from its governing council meetings. Draghi is due to begin speaking at 13.30 UK time.
