Our empirical investigation shows that the intertemporal dynamics of China's central parity are not the same before and after this policy change. They are more variable and have a few new determining factors. Both the deviation of the RMB offshore rate from the central parity and the US dollar index are the two significant determinants of the central parity both before and after the policy change. The VIX index has explanatory power before August 2015, but not after. After August 2015, the onshore RMB rate and the difference between the one-month offshore and onshore RMB forward points show a significant impact on the central parity. While the US dollar index effect remains, we find no evidence of a role for the RMB exchange rate against the currency basket revealed by China in December 2015 in the fixing process.

The volatility impulse response (VIRF) methodology introduced by Hafner and Herwatz (2006) is applied to several shocks between January 2012 and December 2019. Furthermore, we propose a novel way of estimating VIRFs based on Bayesian estimation of the MV-GARCH BEKK model. A simple Independence Chain Metropolis-Hastings algorithm allows drawing VIRFs in an efficient manner, allowing to analyse the significance and persistence of volatility shocks and associated volatility spillovers. The VIRF results show that the CNH exchange rate promptly reflects the global market demand and supply, while the CNY exchange rate reacts with a time lag. The VIRF results also show the existence of spillovers between the two markets as the co-volatility increases in response to shocks.

First, there is evidence that LTV cap tightening since 2009 has dampened both borrowers' leverage and credit growth, and that lower leverage has played a major role in strengthening banks' resilience to property price shocks. Second, the effect on loan growth is found to be state-dependent due to loan market disequilibrium, with a much stronger impact on loan supply than on demand, suggesting that calibrating this tool to curb loan growth needs an accurate estimate of both loan demand and supply. Operationally, this could pose challenges for policymakers. Finally, we find evidence of low responsiveness of housing demand to caps on LTV ratios, which is suggestive of a weak direct pass-through of LTV policy to the property market. These findings together support the view that operationally it would be optimal for LTV policy to primarily target household leverage, and that there are limitations in using this instrument to stabilise credit growth and property prices.

We find that an expansion in M2 generally raises the excess yields of the bonds of Chinese local government entities, and the impact is amplified for local bonds issued by local governments that are characterized as having a high degree of existing resource misallocation. Our estimation results confirm that local government bond excess yields can be used as an indicator of the riskiness of Chinese local government debt.

We identify the roles of the onshore and offshore RMB exchange rates and the US dollar index in determining the central parity in a linear regression framework. The effect of the RMB currency basket index, however, is revealed after controlling for multiplicative offshore RMB volatility effects. The offshore RMB volatility exerts a dampening effect on the links between the central parity and its determinants. In the prediction comparison exercise, the three selected models statistically outperform the random walk benchmark. Among these four models, the selected multiplicative specification yields the smallest root-mean squared prediction error and mean absolute prediction error.

As the current monetary policy framework features a multi-instrument mix of liquidity tools and pricing signals, we employ a dynamic-factor modeling approach to derive an indicator of China’s monetary policy stance. Our approach assumes that comovements of several monetary policy instruments share a common element that can be captured by an underlying unobserved component. We use the derived indicator to trace the response of the PBoC to the coronavirus pandemic. The estimates reveal that the PBoC has implement novel policy measures to ensure that commercial banks maintain liquidity access and credit provision during the COVID-19 crisis.

Statistical models are formulated to assess the linkages between the central parity and the alternative variants of the RMB exchange rate, market volatility and selected control variables. In a linear regression framework, we identify the roles of the onshore and offshore RMB exchange rates and the US dollar index, but not the RMB currency basket index. However, the marginal effect of the RMB index is revealed via a multiplicative interaction model that incorporates a condition variable given by the volatility of the offshore RMB market. The offshore RMB volatility exerts a dampening effect on the links between the central parity and its determinants, reflecting that Chinese authorities do not hesitate to adjust their policy actions under threat of high volatility.

The empirical results confirm the unidirectional spillover in bond return from the US to ASEAN4, while there is a bidirectional influence in volatility. Additionally, dynamic conditional correlation (DCC) analysis is employed to depict the changing correlation in volatility. The empirical results also show that the yields of ASEAN4 bonds increase with emerging market risks, and the exchange rate can act as a buffer to reduce spillover. Given that ASEAN4 governments have issued a large number of government bonds to finance their large fiscal spending during the ongoing COVID-19 pandemic, the return and volatility spillovers from the US to ASEAN4 could be important factors to consider when the US unwinds its unconventional monetary policy and normalizes its interest rates in the medium to long term.

We first estimate exchange rate pass-through to import prices and then from import price to domestic inflation using a Phillips-Curve model. We find that Hong Kong’s exchange rate pass-through to import prices is relatively high compared to the OECD average, although Hong Kong also witnessed a decline of pass-through after 1991. With respect to exchange rate pass-through to domestic prices, we find that a 10 % depreciation of the US dollar against all currencies except for the Hong Kong dollar would lead domestic prices to increase by 0.82 and 1.61 percent in the short run and medium run, respectively. These results are also broadly consistent with those obtained from a calibration exercise that estimates exchange rate pass-through to domestic prices via channels of the tradable and non-tradable goods.

Global banks are found to buffer parent-bank liquidity shocks by repatriating cross-border internal funding, leading to reductions in loan supply by branches in Hong Kong. Branches with a higher loan-to-asset ratio are estimated to cut loan supply sharper than their counterparts. More liquid assets held by parent banks and central bank liquidity are

As the revamped policy arrangement now features a multiple-instrument mix of liquidity tools and pricing signals, we employ a dynamic factor modelling approach to derive an indicator of China’s monetary policy stance. The approach is based on the notion that comovements in several monetary policy instruments have a common element that can be captured by a single underlying, unobserved component. To clarify and interpret the derived index, we employ a baseline DSGE model that can be solved analytically and allows tracing of the expansionary and contractionary on-and-off phases of Chinese monetary policy.
