- Jackson Hole shows divergence in global central banks and dyssynchronization in global economic cycle. Yield surging to new highs and splitting from gold. A paradigm shift is afoot, but near term the US sell-off is abating.
- The market is well versed with the stamp duty cut and its effects. The sentiment boost from such a cut will be fleeting, but its policy intent should not be unheeded.
- Economic fundamentals, as reflected in the cyclical asset prices, have so far failed to respond to policies as they used to. More needs to be done, and will be.
US-China yield gap widens to record.
Jackson Hole has made its name, not just because at its inception it had attracted fishing-aficionado Paul Volker with its pristine fishing locales, but also because Bernanke unveiled two of his QEs masterfully at this summit. Not to mention back in 2014 Draghi stealing the show with his “bazooka” and Kuroda asserting “policy easing not even half done”. Even the PBoC went into a stimulating mode in 2014, probably due to the downtrodden property sector after a clampdown in speculation.
That was a time when the central bankers of the world united as Fantastic Four. Now the economic cycles of world appear desynchronized after COVID, countries are confronted with different demons to fight. China is on the verge of deflation, while the US is still reining in inflation. Consequently, the US-China yield gap has widened to one of the largest on record. And the US 10-year yield has surged to its highest in 15 years (Figure 1).

Historically, US-China yield gap correlated closely with the RMB exchange rate. As yield gap widened, the depreciation pressure on the Chinese yuan aggravated (Figure 1). Such yield difference explains the fluctuations in the offshore RMB exchange rate since we have data, as well as the direction of the Chinese stock market. After all, the Chinese stocks are priced in RMB. And for foreign investors, exchange gains and losses are part of their return.
As the RMB is such an indicator of risk appetite, it is no wonder that the PBOC has intensified its defense against the Yuan depreciation at around 7.30. And the PBoC is a formidable player, with the bigger forex war chest of the world at its disposal. During the past week, it set the RMB reference rate at the largest difference from open bidding, and had just issued 950-million-yuan worth of RMB bond offshore to mop up the excess RMB liquidity. This policy combo once again suggests that around 7.30 level should be the current cyclical low for the RMB exchange rate (Figure 2).

A paradigm shift.
Cross-asset prices movements suggest that a paradigm shift is underway. This is shown by the sudden divergence of prices that used to move in tandem. For instance, after the Jackson Hole summit, US 10-year yield has surged to fresh new highs since mid 2008, and has taken out the previous peak we saw in late October last year. While surging long yields have been headwind for gold price in the past, this time around gold price has remained resilient, and hovering around its all-time-high (Figure 3).

Such breakdown in correlation between two important asset prices suggests a paradigm shift. It appears that the US treasury as the anchor of global risk-free rate is being challenged, as seen in the sovereign rating downgrade by Fitch. And gold as the bedrock for perpetual credit, as it has been in human history, is starting to shine again.
Meanwhile, we are also detecting other breakdowns in cross-asset correlations. For instance, the PBoC’s balance sheet expansion, together with the accumulation of China’s FX assets, seems to have failed to support the RMB exchange rate and China’s long yield in this cycle (Figure 4). This is consistent with the market’s desperation for policies to move the market.
That said, consensus may have misunderstood the effect of policy easing on the RMB exchange rate. Many believe that cutting interest rate would further pressure the RMB. We beg to differ – it is dichotomy: only when policy easing fail to lift economic growth, or the expectation for such growth, then easing would mean weaker RMB. Otherwise, the RMB should strengthen on the back of growth expectations. After all, the RMB is a cyclical asset and one of the important risk indicators for the market. Why else would the PBoC defend it with such zeal.

Stamp duty is cut. Now what?
As we were writing on a Sunday afternoon, there came the news that stamp duty would be cut half on Monday. Indeed, for the past two weeks the market has been whispering a stamp duty cut coming soon. And now the regulator has spoken.

That said, the market is well versed with the benefits of a stamp duty cuts. After all, the rumor has been around, and its effect on stock prices in the short-term is well understood – when cut, stocks rise in the near term.
However, margin trade as a percentage of total turnover continues to recede from its recent highs. Historically, this metric has been a consistent market sentiment gauge, and tends to lead the market by up to three months (Figure 5). As such, since the pre-announced stamp duty cut has failed to lift the market, its sentiment boost can be transient, but its policy signal should not be unheeded.
Conclusion
The 2023 Jackson Hole Summit continues to show divergence between the world’s two most important central banks’ policy choices, as well as the dyssynchronization of global economic cycle. The US-China yield gap widens to record, heralding a paradigm shift and looming market risks in the coming months.
In the near term, however, there are signs that the US sell-off is abating, and stamp duty in China is cut. Rumors about such a cut has been circulating in the market for some time and its effect on the market is well known. As such, its sentiment boost will be fleeting, but its policy intent should not be unheeded.
