Beijing Won't Dump Treasuries, But It Might Stop Buying Them, Reinhart Says

Ask any Wall Street pundit about the possibility that Beijing might dump its dollar reserves and, odds are, their reaction will range from casual dismissal to outright ridicule. Why would Beijing risk saddling the PBOC with losses and driving up the value of the yuan, they might argue, when they have plenty of other options for retaliating against the US?

At first brush, at least, these seem like plausible reasons to dismiss Beijing's aggressive rhetoric. But with the PBOC emerging again as a net seller of Treasuries last month, contrarians are warning that investors shouldn't be so dismissive: If Washington follows through with plans to slap 25% tariffs on another $300 billion in Chinese goods, it's not outside of the realm of plausibility that Beijing could determine that the costs would be well worth the hit to American markets and the economy.

Now, economists are beginning to acknowledge a middle ground. Over the weekend, Harvard Economist Carmen Reinhart, who earned notoriety after the crisis thanks to her work with Ken Rogoff, told her audience during an event organized by Nomura that although she doesn't believe China will dump Treasuries wholesale, it's certainly possible - if not likely - that Beijing will slow its purchases to diversify its assets.

"The scary scenario that China’s going to come in and sell U.S. Treasuries wholesale, I don’t think that’s going to happen," Reinhart said.

However, while explaining her reasoning, Reinhart repeated a canard that, for whatever reason, has been widely accepted by economists: That Beijing would brook losses if it decided to liquidate its Treasury holdings. However, over the past ten years, the PBOC has bought the bonds at an average yield of 3.3%. That leaves room for Beijing to sell $700 billion of its $1.1 trillion pile before pushing yields to the breakeven point (note: Beijing owns roughly 5% of Treasury debt).

"China’s approach is also very pragmatic. Do you really want to sustain a capital loss? They’re the largest holder, does it even make sense? No."

Instead, Reinhart argued that the 'the flows are where the action is.'

"I think the flow is where the action is, namely that purchases of U.S. Treasuries are going to slow."

While that may be true in some sense, TIC data suggests that the truth is more alarming. The PBOC returned to selling last month after three months of net accumulation.

But the drawdown since mid-2018, around the time that the trade relationship between the world's two largest economies really started to unravel, is difficult to ignore.

Conveniently enough, Reuters on Tuesday published an explainer listing some of the reasons why Beijing likely won't opt for what has been deemed 'the nuclear option' (Text courtesy of Reuters):

HOW MUCH U.S. DEBT DOES CHINA OWN?

About a decade ago, China overtook Japan as the largest foreign holder of U.S. government debt.

Its holdings stood at more than $1.12 trillion at the end of March, according to U.S. Treasury department data. Japan is a close second with nearly $1.08 trillion.

China’s holdings peaked in late 2013 at nearly $1.32 trillion and have come down by about 15% since then. In March they were the lowest in about two years.

Its share of the Treasury market has fallen even faster, due to the steady issuance of U.S. debt required to finance the growing federal budget deficit.

The world’s second biggest economy owns about 7% of the $16.18 trillion of U.S. public debt outstanding, its lowest share in 14 years, and down from a peak of 14% in 2011. Still, its slice of the pie is exceeded only by the U.S. Federal Reserve, which owns $2.15 trillion of Treasuries, or 13.5% of the market.

Treasury issuance is expected to keep accelerating following a massive tax cut enacted in December 2017, so China’s share of the market will likely drop even further.

WHY DOES CHINA OWN SO MUCH U.S. DEBT?

As a net exporter to the United States and the rest of the world, China has the world’s largest stash of foreign-exchange reserves at more than $3 trillion. Much of that is denominated in U.S. dollars accumulated through its persistent trade surplus with the United States since the early 1990s.

A natural place for China to park a lot of those greenbacks is the U.S. Treasury market, which is by far the largest and most liquid pool of safe assets in the world.

Also, since the financial crisis of 2007-2009, U.S. Treasuries have consistently yielded more than bonds issued by other large developed economies such as Japan and Germany, which has been another lure.

WHAT IS THE RISK TO THE UNITED STATES IF CHINA SELLS?

Most analysts agree that large-scale selling by Beijing would disrupt the Treasury market and other markets.

An abrupt shift in the balance of supply and demand could drive down Treasury prices, and drive up their yields, which move in the opposition direction to prices. That would cause a spike in borrowing costs for the U.S. government.

Also, because Treasury yields are a benchmark for U.S. consumer and business credit, interest rates on everything from corporate bonds to homeowners’ mortgages would rise, likely slowing the economy.

Such a jarring move would also erode global investors’ confidence in the U.S. dollar as the world’s top reserve currency.

WHAT IS THE RISK TO CHINA IF IT DUMPS TREASURIES?

Most analysts argue China has not opted to sell Uncle Sam’s IOUs because a nosedive in U.S. bond prices also would bring down the value of China’s remaining Treasury holdings.

Also, China’s currency, the yuan, is not fully free floating. Beijing uses its Treasury holdings as a key tool to stabilize the yuan within a targeted range, against the dollar in particular.

Some critics have alleged China uses Treasuries and its other currency reserves to hold down the yuan, making its exports more attractive. At the same time, allowing the currency to cheapen too much risks other problems, such as foreign capital flight.

Any sharp depreciation in the greenback might force Beijing to defend the yuan, which may mean shedding more of its Treasuries stake. Back in 2016, China’s Treasuries holdings fell sharply by some $200 billion from May to November of that year as the yuan depreciated on worries about the Chinese economy.

Lastly, any knock-on effect in the U.S. economy would also be felt in China because the United States is the destination for nearly a fifth of Chinese exports.
