I’ll have to think through this before reaching any firm conclusions, but I’m dubious that what has been called the Chinese “nuclear option” of selling its T-bills is likely to be a very effective tactic.
If there is any further pushback from the US on any of these Chinese projects in Iran, then Beijing will invoke in full force the ‘nuclear option’ of selling all or a significant part of its US$1.4 trillion holding of US Treasury Bills, with a major chunk of the paper due to be sold in September on this basis. This massive holding of these bonds – through which the US finances its economy and is an important factor both in the value of the dollar and therefore in the health of US international companies especially – has been used as a bargaining chip before by China, especially when it feels threatened. Back in 2007, just before the great financial crisis, a number of senior Chinese figures at various state-run think tanks – through which China often signals its big geopolitical threats – stated that the large-scale selling of this massive Treasury Bill holding would trigger a dollar crash, a huge spike in bond yields, the collapse of the housing market and stock market chaos.
Such a tactic would neatly fit into China’s overall strategy to have the renminbi challenge the US dollar’s status as the key global reserve currency and the prime currency for global energy transactions. “The long-planned sequencing for this was inclusion in the SDR {Special Drawing Rights] mix, which happened in 2016, increasing use as a trading currency, which followed that, use as the key currency of an international energy trading exchange, which has occurred with the creation of the renminbi-denominated Shanghai International Energy Exchange in last year, and the calls from big oil producers and other major trading nations to use the renminbi, which has been happening over the past few years,” the head of a New York-based commodities hedge fund told OilPrice.com. Only recently, Leonid Mikhelson, chief executive officer of Russian oil major, Novatek, said that future sales to China denominated in renminbi is under consideration and that US sanctions accelerate the process of Russia trying to switch away from US dollar-centric oil and gas trading and the damage from potential sanctions that go with it. “This has been discussed for a while with Russia’s largest trading partners such as India and China, and even Arab countries are starting to think about it… If they do create difficulties for our Russian banks then all we have to do is replace dollars,” he said. “The trade war between the US and China will only accelerate the process,” he added.
At first glance, it looks to me the potential US response of simply repudiating its debt and declaring those T-bills to be of no value will be considerably more harmful to China than selling the debt will be to the USA.
Those who are focused on posturing and threats never seem to keep in mind that the enemy always gets a vote.
