This paper analyses inflation dynamics in the Central African Economic and Monetary Community (CEMAC) using a constructed dataset for country-specific commodity price indices and panel cointegrated vector autoregressive (VAR) models. Imported commodity price shocks are significant in explaining inflation in the region. Governments are another driving force of inflation dynamics mainly through controlled prices and the role of capital expenditure in domestic activity. In most CEMAC countries, the largest effect of global food and fuel prices occurs after four or five quarters in noncore inflation and then decays substantially over time. Second-round effects are significant only in Cameroon and to a lesser extent in the Republic of Congo.

As in the rest of the world, inflation in CEMAC surged more quickly and persistently than expected during the 2021–23 period. This paper examines the drivers of inflation dynamics and the contribution of global shocks to inflation persistence in CEMAC. We use a Phillips curve framework combined with the local projections method. Our results confirm the prominent role of global factors in driving inflation dynamics. Global commodity food and oil price fluctuations, and shipping costs are the main factors explaining the large variability in headline inflation. Further, we find that global price shocks have sizable and persistent effects on domestic headline inflation, with differences in the magnitude and speed of pass-through. The pass-through from commodity food price fluctuations to headline inflation is higher and more persistent than that of other global price shocks, reflecting the large share of food in the consumption baskets, which makes inflation more vulnerable to direct effects of international food shocks, but also larger second-round effects.

After trailing Euro Area inflation closely in the recent past, inflation in the Western Balkans has accelerated faster since early 2022 on the back of the shocks to global commodity prices, strong recovery from the pandemic, and lingering supply bottlenecks. This paper employs two complementary empirical approaches of an augmented Phillips curve and structural VAR, adapting them to the data availability and country specificities of the Western Balkans, to analyze the inflation dynamics in the region. It finds that international food prices affect not only headline but also core inflation as well as inflation expectations. Further, inflation in the Western Balkans is not just determined by foreign shocks, and domestic factors, aggregate demand shocks in particular, have a significant impact on inflation. These findings imply a possible role for policies to temporarily limit an immediate and complete pass-through of international to domestic food prices while also stressing the importance of an appropriate domestic macroeconomic policy mix to keep inflation expectations anchored and safeguard credibility in the face of high inflation persistence.

This paper investigates the response of consumer price inflation to changes in domestic fuel prices, looking at the different categories of the overall consumer price index (CPI). We then combine household survey data with the CPI components to construct a CPI index for the poorest and richest income quintiles with the view to assess the distributional impact of the pass-through. To undertake this analysis, the paper provides an update to the Global Monthly Retail Fuel Price Database, expanding the product coverage to premium and regular fuels, the time dimension to December 2020, and the sample to 190 countries. Three key findings stand out. First, the response of inflation to gasoline price shocks is smaller, but more persistent and broad-based in developing economies than in advanced economies. Second, we show that past studies using crude oil prices instead of retail fuel prices to estimate the pass-through to inflation significantly underestimate it. Third, while the purchasing power of all households declines as fuel prices increase, the distributional impact is progressive. But the progressivity phases out within 6 months after the shock in advanced economies, whereas it persists beyond a year in developing countries.

This paper investigates the evolution of inflation dynamics in the five largest ASEAN countries between 1997 and 2017. To account for changes in the monetary policy frameworks since the Asian Financial Crisis (AFC), the analysis is based on country-specific Phillips curves allowing for time-varying parameters. The paper finds evidence of a higher degree of forward-looking dynamics and a better anchoring of inflation expectations, consistent with the improvements in monetary policy frameworks in the region. In contrast, the quantitative impact of cyclical fluctuations and import prices has gradually diminished over time.

Inflation rates rose sharply in the Philippines during 2018. Understanding the demand and supply sources of inflation pressures is key to monetary policy response. Qualitatively, indicators have pointed to evidence of inflation pressures from both sides in 2018, with the supply factors, by and large, associated with commodity-price shocks and demand factors deduced from gleaning at the wider non-oil trade deficits seen in the Philippines. Quantitatively, we deploy a semi-structural model to decompose the contributions of various shocks to inflation. Our main findings are (1) supply factors (mainly global commodity prices) played a prominent role in explaining the rise in inflation in 2018; (2) demand factors also contributed to inflation in a non-negligible way, justifying the need for tighter monetary policy in 2018; (3) the size of the estimated output gap (an important indicator of demand pressures) could be larger, when considering the widening trade deficits in 2018; and (4) a delayed monetary policy tightening can be costly in terms of higher inflation rates, requiring larger and more aggressive interest rate hikes to bring inflation under control, based on a counterfactual exercise.
