Four scatterplots share x-axes and y-axes, with data points representing causal associations between FSI and BTC. Top left scatterplot: RWWQGC: BTC -> FSI (τ = 0.05); data points show causal associations. Top right scatterplot: RWWQGC: FSI -> BTC (τ = 0.05); data points show causal associations. Bottom left scatterplot: RWWQGC: BTC -> FSI (τ = 0.5); data points show causal associations. Bottom right scatterplot: RWWQGC: FSI -> BTC (τ = 0.5); data points show causal associations.Time-frequency-quantile causal associations between FSI and BTC. The window size is 250 and the step size is 10
