Abstract: The purpose of this study was to analyze the irregular pattern of changing inflation
as a result of the pass-through of the exchange rate and fluctuations in oil prices in the current
globalization scenario. We used annual data sets for crude oil prices, real effective exchange rates,
and inflation in Pakistan from 1972 to 2021 for the analysis. The control variables used in the current
study were imports (IMP), gross domestic product per capita (GDP), exports (EXP), globalization
(GLOB), and interest rates (CRATE). Our findings from a non-linear autoregressive distributed lag
(NARDL) analysis showed that inflation had an asymmetric rocket and feather pattern regardless of
how globalization was defined or measured. On the other hand, GDP, EXP, and GLOB negatively
impacted inflation, and CRATE and IMP had positive effects on inflation. Our study suggested that
alternative policies, such as fixing the exchange rate, might decrease uncertainty and stabilize the
Pakistani economy in the future. Moreover, increasing the use of sustainable energy would reduce
the dependence of the economy on oil prices, which would lower its impact on the economy.
Keywords: real effective exchange rate; oil prices; inflation; non-linear autoregressive distributed lag;

1. Introduction
Inflation primarily refers to persistent increases in the prices of goods and services. A
rise in the prices of commodities leads to a decrease in the purchasing power of the people
in society. The decline in the purchasing power of individuals in the economy eventually
leads to a reduction in the level of savings and investments in the economy [1]. Oil is
an imported good and the exchange rate affects the price of oil immensely. Therefore,
understanding the relationship between the exchange rate and the price of oil and its
pass-through on inflation is critical for developing economic policies [2]. Fluctuations
in exchange rates play a crucial role in shaping the economic link or as a transmission
mechanism between domestic and international markets, directly affecting the prices of
goods and services in the domestic economy [2]. Exchange rate movements can influence
actual inflation and future price movements. Macroeconomists simultaneously linked oil
price shocks to diminished economic activity and higher inflation [3]. As Lescaroux and
Mignon [4] observed, several transmission networks exist through which oil prices can
influence economic activity and inflation. For instance, a surge in the price of crude oil
affects the prices of petroleum products, eventually affecting consumers and producers.
This is because crude oil prices directly affect the prices of energy-related items, such as
household fuels, electricity, and motor fuels. From the production side, a rise in the price of
crude oil increases production costs, which lowers the overall output, employment, real
wages, investments, and profits.
The government does not fix the exchange rate at a specific level but lets the supply
and demand for the currency determine the exchange rate [4]. The participation of the
