Item Open Access Commonality in FX liquidity: High-frequency evidence(Elsevier, 2020-06) Şensoy, Ahmet; Uzun, Sevcan; Lucey, B. M.We test the existence and reveal the main properties of commonality in liquidity for the foreign exchange (FX) markets at the high-frequency level. Accordingly, commonality in FX liquidity exists even at the high-frequency level and it has been gradually increasing over the last few years. Moreover, commonality increases significantly before (after) ECB (Fed) monetary policy announcements. Finally, commonality in FX liquidity has a significant positive impact on the commonality in FX return series, indicating that an increase in the intraday systematic liquidity risk might trigger a negative aggregate liquidity-return spiral in the FX markets.Item Open Access Multiscale systematic risk(Pergamon Press, 2005) Gençay, R.; Selçuk, F.; Whitcher, B.In this paper we propose a new approach to estimating systematic risk (the beta of an asset). The proposed method is based on a wavelet multiscaling approach that decomposes a given time series on a scale-by-scale basis. The empirical results from different economies show that the relationship between the return of a portfolio and its beta becomes stronger as the wavelet scale increases. Therefore, the predictions of the CAPM model should be investigated considering the multiscale nature of risk and return. © 2004 Elsevier Ltd.

K.; Şensoy, AhmetWe introduce time-varying systematic yield risk (SYR) and systematic liquidity risk (SLR) measures for sovereign bond markets of the major European Monetary Union (EMU) country members. Using daily sovereign bond data, our analysis shows that trend components of both types of risk are strongly positively correlated. Vector auto-regression and generalized impulse response analysis reveal that shocks to the SLR has significant impact on SYR lasting up to 5 days, whereas shocks to the SYR has no significant impact on SLR. Since mid-2015, both risks are gradually increasing and as of 2018, they are at their highest levels over the last five years.
