One of the big question now being debated is 'What would happen if China were to dump its entire Treasury portfolio in one fell swoop?' Caroline Baum addressed that question in China Doesn't Steer the U. S. Interest-Rate Ship. BEA 4th Quarter GDP 1st Estimate 0.7% Q&A: Why Did GDPNow Rise After Durable Goods? When are Construction Revisions Coming? Like a highly contagious virus, fear that foreigners will dump all their U. S. Treasury securities spreads through the market at periodic intervals. The fear is not totally unfounded. Foreigners own a little more than half of publicly held U. S. government securities, according to the Treasury Department. So if these foreigners -- both central banks and private investors -- woke up on the wrong side of the bed one morning and decided to give the Treasury portfolio the old heave-ho... well, you can begin to understand the basis for the recurrent nightmare. 'When people say, what happens when foreigners dump U. S. securities, I say, tell me why,' says Jim Bianco, president of Bianco Research in Chicago. 'It's never happened before' on a long-term basis. The latest bout of flu-like symptoms was triggered by news earlier this year that the People's Bank of China was setting up an investment vehicle to diversify its $1.2 trillion of dollars. Last month, China announced it was investing $3 billion of its dollar reserves in Blackstone Group LP, manager of the second-largest buyout fund, to boost its returns. What if China were to shoot itself in the foot and dump its entire Treasury portfolio in one fell swoop? It just so happens we have a real-world example of what it would mean, according to Bianco. The Bank of Japan bought $244 billion of Treasuries in the 12 months ended August 2004. During that time, U. S. long-term interest rates rose and the dollar fell versus the yen. By April 2006, the BOJ was a net seller of U. S. Treasuries (on a 12-month basis) to the tune of $26 billion, a swing of $270 billion. U. S. interest rates fell during that period while the dollar rose. While I agree with Bianco that no one noticed when Japan stopped buying, that simply is not a valid model for what would happen if China (or Japan) were to. There is a big difference between stopping additional purchases (or selling them slowly over a period of time), than a massive dump of selling everything at once. ' about what might happen? Nonetheless I am sympathetic towards what I believe to be a key idea of the article: that China or Japan stopping additional purchases or divesting slowly over time, does not spell disaster. Perhaps it will, perhaps not. There IS a real world example of that, with falling treasury yields to boot. On that score it's as Caroline suggests ' There is little reason to fear a wholesale pullout by China from U. S. government bonds, former Federal Reserve Chairman Alan Greenspan said Tuesday. While expressing concerns about China's runaway growth rate and what he described as overvalued stocks, Greenspan played down the prospect that Chinese authorities would sell Treasurys in earnest, forcing a sharp spike in U. S. interest rates. Asked at a commercial real estate conference if investors should be worried about this oft-cited concern, Greenspan said: 'I wouldn't be, no.' Greenspan said the reason such a withdrawal was unlikely was that China would not have anyone to sell the securities to. Greenspan said that a global liquidity boom, which he traced back to the end of the Cold War, would not go on forever. 'Enjoy it while it lasts,' he told the audience. Now a private-sector consultant following more than 18 years at the U. S. central bank, Greenspan reiterated his prediction that China's latest growth spurt had come too far, too fast. 'We cannot continue this rate of growth in China and the Third World. This cannot continue indefinitely,' Greenspan said in a speech. 'Some of these price/earnings ratios are discounting nirvana.' '. So instead of accumulating more treasuries, China is plowing US dollars into inflated US stocks, agencies (tied to horrendous fundamentals in the US housing market), junk bonds and other garbage. Why is it that foreigners always seem to buy market tops (first treasuries, now equities)? Regardless of the answer to that last question, there's always a buyer at the right price. That holds true for housing, treasuries, and even CDOs. Let’s have a count of hands please: Other than bond funds that deal in treasuries, is there anyone anywhere that has anything positive to say about treasuries? Has such pessimism at market bottoms ever in history been rewarded? There’s no denying that China has cut back on Treasury purchases. In fact, avoidance of U. S. treasuries in now approaching a near mania everywhere, even as funding can easily be found for the junkiest of junk offerings (not related to housing). But is there any reason for China to do a wholesale dump? I personally doubt it. If you disagree tell me how it suits China's interest to massively dump treasuries in one fell swoop. More to the point, is lack of foreign demand the reason for the recent bond selloff? That’s what everyone seems to believe, but if that is the reason then what’s the explanation for falling yields as Japan was selling? You can't have it both ways. Greenspan has been wrong at every major turning point his entire career. The fact that Greenspan states there would be no buyers could be yet another of a long series of contrary indications suggesting that internal demand just might be ready to soar. If that's the case, the real question then is: 'How high do yields get in the meantime?' as opposed to these unlikely 'What If?' scenarios. As an aside, the higher rates get in the meantime the bigger the debacle in housing. It’s a no win situation for the Fed.
