On August 23, at the global central bank governors' meeting, Federal Reserve Chairman Jerome Powell delivered a significant speech, indicating that the time for "policy adjustment has come." This proclamation has led to widespread market anticipation of an impending interest rate cut by the Fed in SeptemberGiven this backdrop, there is an expectation that the previously inverted yield spread between Chinese and U.Sgovernment bonds may gradually narrow, encouraging a restorative appreciation of the Renminbi, or Chinese currency.

The current Federal Reserve's decision to potentially lower interest rates is largely seen as a precautionary measure, likely to be implemented gentlyMeanwhile, domestic factors in China, including a downturn in the real estate market and a lack of effective domestic demand, suggest that the country's monetary policy will maintain a stable yet slightly loose stance for the foreseeable future

This raises important questions: Can the Renminbi rebound quickly in the short term? Is there a possibility for a significant unilateral appreciation within the later months of this year and early next year? This article explores these intricate dynamics.

The Impact of Rate Cuts on the Dollar's Strength is Complex

Since the 1990s, the Federal Reserve has undergone six substantial periods of interest rate reductionsAmong these instances, two were purely precautionary cuts, while three were strictly for relief, with the remaining instance being a mixed approach of both typesA fascinating element of these periods is the contrasting effects on the value of the dollar.

For instance, during the first precautionary rate cut period from July 1995 to January 1996, the federal funds rate decreased from 6% to 5.25%—a total reduction of 75 basis points

Interestingly, during this time, the dollar index rose from 81.6 to 87.4. This upward movement was attributed to the robust economic policies enacted by President Bill Clinton, who managed to establish a federal budget surplus through increased taxes and deficit reduction while the burgeoning internet technology spurred a new wave of market optimism.

Conversely, during the second precautionary cut from September to November 1998, the federal funds rate dropped from 5.5% to 4.75%. Despite the ongoing general strength of the dollar, the index temporarily dipped from 100 to around 96 before rallying again and surpassing 120 by early 2002. This exemplifies how the interplay of various economic factors can produce opposite outcomes even within similar monetary policy frameworks.

Considering the differences in duration and magnitude between these historical rate cut cycles compared to the current expectations—which foresee a potential duration of 14-16 months and 6-8 reductions totaling 150-200 basis points—it becomes clear that the relationship between interest rate adjustments and currency strength is multifaceted and influenced by a spectrum of additional factors.

Firstly, various determinants influence the trajectory of the dollar's exchange rate

While changes in Fed policy form part of this landscape, they alone do not dictate trendsA significant factor is also the prior performance of the dollar before the rate cuts are announcedA prolonged period of dollar strength may predispose it to a temporary weakening once rates are reducedSecondly, for shorter precautionary cuts with mild adjustments, the muted impact on the dollar's decline is compounded by the absence of considerable economic shifting forces, likely leading to a stronger dollar again after the cut period concludes.

Therefore, as we analyze potential paths forward, it seems plausible that with shifting global political and economic circumstances, particularly following changes in U.Spolitical leadership, renewed phases of dollar strength could re-emergeInfluencing factors include a sudden rise in U.STreasury yields from market concerns regarding fiscal deficits and tax cuts or changes in the dynamics of U.S.-China relations

Historically, improved relations between these two global heavyweights have often led to a calming of global trade tensions and a corresponding decline in the dollar index, whereas tensions typically bolster it, reflecting a fraught global marketplace.

The Strengthening Correlation of the Renminbi Against the Dollar

Given that the dollar remains the world’s principal currency for pricing, transactions, and reserves, discussions of currency exchange rates often center around a country's currency in relation to the dollarNotably, while the renminbi’s valuation is influenced by other factors, the dollar index's trajectory significantly impacts its rate.

There is consistent correlation observed among the three major yuan-to-dollar exchange rates: the midpoint, offshore, and onshore prices, especially since April 2016. Since then, the relationship between the yuan and the dollar index has tightened considerably, nearly reaching a correlation coefficient of 0.7 since 2019.

Moreover, this correlation extends to the CFETS yuan exchange rate index, which measures the renminbi's value against a basket of currencies from China's key trading partners

Despite variation in the weight of currencies, a significant correlation of about 0.6935 was recorded from August 2023 to August 2024, rising sharply to approximately 0.9475 in 2024. This trend indicates that the dynamics of the dollar index will inevitably reflect upon the fluctuations in the yuan.

The Prospects of Renminbi Appreciation in the Near Term

During the current interest rate reduction cycle, the renminbi could initially appreciate as the yield spread between Chinese and U.Sgovernment bonds narrowsThe yield gap had widened considerably following the Fed's rate hike initiation in March 2022, but signs of reduction have started to surface as Fed rate cut expectations gain traction.

Despite this potential for short-term appreciation, four key considerations may limit the extent of any gains

The anticipated 150-200 basis point reduction may nominally offset the existing yield gap, thus limiting unilateral appreciation of the yuanAdditionally, macroeconomic factors, including geopolitical tensions, may uphold a fluctuating scenario for the dollar.

Previous patterns illustrate that loosening monetary policy within China usually stabilizes or even depresses currency values rather than enhances them historicallyThe PBOC likely will leverage this window to adjust rates and implement other policies to stimulate the economy, which may offset any upward momentum from the Fed's actions.

Furthermore, underlying economic fundamentals are critical for assessing currency strengthHistorically, notable yuan appreciation against the dollar coupled with robust economic growthNonetheless, current economic indicators suggest ongoing difficulties, such as sluggish growth rates, remaining well below expectations and indicating persistent weaknesses in various sectors, including real estate.

In summary, while the Fed's decisions will alleviate some of the depreciation pressure on the yuan that has persisted over years of tight monetary policy, the broader expectation is for the renminbi to see partial appreciation
