This paper presents the main findings of an International Banking Research Network initiative examining the interaction between monetary policy and macroprudential policy in determining international bank lending. We give an overview on the data, empirical specifications and results of the seven papers from the initiative. The papers are from a range of core and smaller advanced economies, and emerging markets . The main findings are as follows. First, there is evidence that macroprudential policy in recipient countries can partly offset the spillover effects of monetary policy conducted in core countries. Meanwhile, domestic macroprudential policy in core countries can also affect the cross‐border transmission of domestic monetary policy via lending abroad, by limiting the increase in lending by less strongly capitalized banks. Second, the findings highlight that studying heterogeneities across banks provides complementary insights to studies using more aggregate data and focusing on average effects. In particular, we find that individual bank characteristics such as bank size or GSIB status play a first‐order role in the transmission of these policies. Finally, the impacts differ considerably across prudential policy instruments, which also suggests the importance of more granular analysis.

Estimating Option-implied Risk Aversion for Indian Markets

with Bandi Kamaiah

What do nearly 1.5 lakh observations of options data say about risk preferences of Indian investors? This paper explores a nonparametric technique to compute probability density functions (PDFs) directly from NIFTY 50 option prices in India, based on the utility preferences of the representative investor. Use of probability density functions to estimate investor expectations of the distribution of future levels of the underlying assets has gained tremendous popularity over the last decade. Studying option prices provides information about the market participants’ probability assessment of the future outcome of the underlying asset. We compare the forecast ability of the risk-neutral PDF and risk-adjusted density functions to arrive at a unique index of relative risk aversion for Indian markets. Results indicate that risk-adjusted PDFs are reasonably better forecasts of investor expectations of future levels of the underlying assets. We find that Indian investors are not neutral to risk, contrary to the theoretical assumption of risk-neutrality among investors. The computed time-series of relative risk aversion overcomes the limitations of the VIX (implied volatility index) to yield a more reliable index, particularly useful for the Indian markets. Validity of the computed index is established by comparing with existing measures of risk and the relationships are found to be consistent with market expectations.
