In　this　uncertain　world,　every　economy　is　facing　challenges　to　achieve　sustainable　development　with　available　resources.　Ample　research　has　explored　the　nexus　of　natural　resources　and　financial　development.　However,　world　uncertainty　and　financial　development＇s　nexus　are　uncommon　in　literature.　Therefore,　this　study　is　planned　to　re-investigate　the　nexus　of　natural　resource　rents　and　financial　development　by　recruiting　world　uncertainty,　human　capital,　and　consumer　price　index.　Theoretically,　the　natural　resource　curse　hypothesis　is　being　followed.　To　empirically　estimate　the　linkages,　＇the　Method　of　Moments　Quantile　Regression　(MMQR)＇　and　＇Bootstrap　Quantile　Regression　(BSQR)＇　are　employed.　Findings　report　the　negative　role　of　world　uncertainty　with　the　existence　of　the　natural　resource　curse.　Whereases,　human　capital,　and　consumer　prices　are　found　to　support　for　financial　development　in　high-income　countries.　High-income　economies　are　suggested　to　invest　more　in　human　capital　and　plan　to　minimize　uncertainty　in　the　long-run.　Findings　have　robust　policy　implications.　©　2023　Elsevier　Ltd
