What a weekend of intrigue. It began on Friday afternoon, not long after the market closed, when most investors had switched off for the weekend.

Treasurer Wayne Swan surprised everyone and rejected China Minmetals’ bid for OZ Minerals in its current form. Nothing like a little Friday afternoon bombshell.

The Treasurer said that Prominent Hill-OZ’s major copper and gold asset in South Australia-is too close to the Department of Defence’s Woomera Testing Facility. It’s about 160km away. Swan said, “The Woomera Prohibited Area weapons testing range makes a unique and sensitive contribution to Australia’s national defence,” and that, “It is not unusual for governments to restrict access to sensitive areas on national security grounds.”

That means you China. Stay away, sort of. That is, Swan did not rule out an alternative bid for OZ that does not, presumably include Prominent Hill.

This is no laughing matter for OZ or its shareholders. The company has $1.3 billion in debt it must refinance by Tuesday. The $2.6 billion bid from Minmetals would have solved that problem. But now the question is whether OZ’s bankers will give it more time, or pull the plug.

Part of this problem is of the company’s own creation. As of August last year, it classified the $1.3 billion in debt as a “non-current liability,” assuming, we presume, that it would be able to refinance that debt easily enough. That was obviously not the case. And now the clock is ticking.

But would the Treasurer make a decision on Friday night that would put the company in receivership by Tuesday? Is the government convinced that OZ is being run by the gang that couldn’t shoot straight and is better off being cut up into parts and sold rather than delivered into Chinese hands whole?

Maybe we’ll never know what the Treasurer is thinking. But it may not matter. The Australian Financial Review reports this morning that Minmetals revised its offer over the weekend. The offer excludes Prominent Hill but includes the Sepon gold mine in Laos and the high-cost but massive Century zinc mine in Queensland. More on this story tomorrow. OZ is currently in a trading halt.

The big G-20 meeting gets going later this week. Stocks in New York were down Friday but have enjoyed a pretty good month so far. Here in Australia, stocks are up 16.75% since the ASX/200 closed at 3,145 on March 6th. Does this rally have legs?

If the market is channeling the market from the Great Depression, then yes, the rally could last months and recoup as much as 50% of the losses since it peaked at 6,828 in November of 2007. It’s hard to say what kind of economic news might come down the pipe to cheer investors that much.

Investors are currently a pretty gloomy bunch. But perhaps the aggressive monetisation of debt by the Fed will drive institutions out of bonds and into stocks. There is a lot of cash in money market funds that could get back into the market and send stocks up quickly.

Or perhaps not to all of that. The Economist Intelligence Unit has just released a report that predicts a 40% chance of global depression. The report is called “Manning the Barricades: Who’s at risk as deepening economic distress foments social unrest.”

To be fair, it also says there is a 60% chance the various stimulus efforts in the developing world successfully stabilise the global economy and share markets. But it says there’s a 30% chance of global depression and a 10% chance of global depression with massive social upheaval.

Magazine cover contrarians know that any time a big claim is safe enough to put on the cover of a mainstream publication, the trend behind it is probably over. If this is the case, the Economist article is a massive buy signal. But it’s also possible the Economist has gone as far as it can without terrifying its readers and more importantly, its advertisers.

In other words, it’s possible that things are a lot worse than the Economist is willing to say, which is not exactly a comforting thought. More on this tomorrow as well.

Amidst all these dire forecasts comes another prediction of higher oil prices. In a Wall Street Journal article on Friday, Richard Jones, the deputy director of the International Energy Agency, said the oil crash of 2008 may prevent around 8 million barrels of oil per day from ever reaching the market.

The oil price crash has caused so many projects to be deferred or cancelled that Jones says, “Unless sufficient companies have the will and financial ability to invest through the downcycle, there is a real risk that supply growth may lag the eventual rebound of demand, leading to substantial price increases — possibly as early as this year.”
