It analyses interconnectedness among a sample cluster comprising Crude Oil, Gold and sixteen global equity markets including developed and emerging based on generalised autoregressive conditional heteroskedasticity (GARCH) and time-varying parameter vector auto regressive model (TVP-VAR) model. The examination of daily data pertaining to various stock markets and global oil prices, gold prices reveals developed stock markets transmits its shocks more than the emerging stock markets and Gold transmits more than Oil.
