FT: "A cheaper renminbi would help Chinese exporters remain competitive in the face of higher tariffs in the US, but it could also leave China open to the accusation of currency manipulation, a charge levelled by the previous Trump administration."

It seems that traders are betting that the combination of an increasingly sluggish Chinese economy and a potential rise in US tariffs will force down the value of the RMB.

But I think this is a much more complicated issue than these traders might think.
3/10
One complication is that devaluing the RMB in response to US tariffs means retaliating not just against the US but in fact against all of China's trade partners. This might simply increase the incentive for the rest of the world to implement tariffs.
4/10
A second complication is that currency devaluation doesn't work the same way in countries with overvalued currencies as in countries with undervalued currencies. In my most recent piece for Foreign Affairs, I quote Ragnan Nurkse who...

said, all the way back in 1942, that “the devaluation of a currency is expansionary in effect if it corrects a previous overvaluation, but deflationary if it makes the currency undervalued.” China's RMB is seriously undervalued, as evidenced by its huge trade surplus.

This creates a problem for China. Like tariffs, currency devaluation works by transferring income from net importers (household consumers) to net exporters (producers). This transfer effectively subsidizes production while taxing consumption. Dani Rodrik makes a similar...

point when he writes, in a recent essay, that "an import tariff is a specific combination of two different policies: a tax on consumption of the imported good and a production subsidy for its domestic supply".

China's problem, as a surplus country, is that it consumes too little to absorb enough of what it produces. By taxing consumption further, however, an RMB devaluation will only help the economy if the rest of the world is able to accommodate much larger Chinese surpluses.
9/10
If not, an RMB devaluation is likely to be contractionary, by reducing domestic demand by more than it expands the trade surplus. In fact my Foreign Affairs article notes that the China faces a similar problem today as the US faced in Smoot-Hawley times.
10/10
For China to devalue the RMB, in other words, is like the US raising tariffs in 1930: it is unlikely to boost growth and, if it leads to retaliation, it will most likely be contractionary. Like tariffs, devaluation is only a "solution" under very specific circumstances.

Gillian Tett: "Indeed, as an IMF blog recently noted, there are already signs that many non-American central banks are diversifying away from the dollar — albeit very slowly and modestly from a high base, and mostly into minor currencies."

I wish this were true, but I doubt it. If you count not just the official reserves of central banks but also hidden reserves held by state-affiliated entities, and certainly if you include all non-US entities, The amount of US assets held by foreigners is rising, not falling.
3/7
How do I know? Because net foreign purchases of US assets are simply the obverse of the US current account deficit, and both have been rising in recent years. Foreigners own more US assets than ever.

FT: "China’s government bond market has opened 2025 with a clear warning for policymakers: without more determined stimulus, investors expect deflationary pressures to become even more entrenched in the world’s second-largest economy."

In fact China does not need "more stimulus" nor even "more monetary easing" to boost inflation and raise bond prices, nor is that what the bond markets are saying. On the contrary, a quick glance at the debt numbers shows that China has had...
3/7
plenty of both, and rather than raise prices, years of more fiscal stimulus and greater monetary easing have in fact accommodated a weakening consumption share of GDP, bigger-than-ever trade surpluses, and disinflation.

consumption of the imported good and a production subsidy for its domestic supply", and of course I fully agree. A tariff is just an industrial policy that works by taxing consumption and subsidizing production. In that sense, it is a lot like devaluing the currency.
3/8
But that is also why I only partly agree with him when he says "Like all barriers to market exchanges, tariffs create inefficiency."

I would argue that, like with currency devaluation, it depends on the underlying conditions.

Very interesting FT article: "Chinese venture capitalists are hounding failed founders, pursuing personal assets and adding them to a national debtor blacklist when they fail to pay up, throwing the country’s start-up funding ecosystem into crisis."

Around 80% of VC deals in the past included redemption provisions, which require issuers "to buy back investors’ shares plus interest if certain targets such as an initial public offering timeline, valuation goals or revenue metrics are not met."
3/6
These VC provisions are a classic form of "inverted" balance sheet structure, exacerbating volatility by reinforcing prices both on the way up and (especially) on the way down. Once the VC bubble ended, it was always likely that these provisions would prove deadly.

Barry Naughton: "Japan spent almost a decade trying to painlessly restructure a financial system that had suffered a huge reduction in the value of its assets. And now China seems to be repeating some parts of that."
thewirechina.com/2025/01/05/bar…
2/16
Naughton is right, and on an issue that is widely misunderstood. The huge surge in China's debt burden has been an enormous problem, but not because the debt itself is the problem. It is just the symptom of the problem.
ft.com/content/630f82…

In itself, debt is simply a set of transfers – an explicit transfer today followed by an explicit or implicit transfer tomorrow.

In China's case, most of the accumulated debt has been used to fund investment, but if this investment had been productive, then by...

It is true that the 1930s were a period of beggar-thy-neighbor trade policies and declining global trade that left the global economy collectively worse off, and that this might hold lessons for us today, but it is important to get the story right.

bloomberg.com/news/newslette…
2/7
One possible story is that everything was going well until various economies, for political reasons, decided to intervene in trade, setting off a sequence of intervention and retaliation that left the global economy worse off.
3/7
Another story is that there already were deep imbalances in the global economy – including those that led Gustav Stresemann to say in 1929 that "Germany is in fact dancing on a volcano. If the short-term credits are called in, a large section of our economy would collapse."
