The Hidden Impact: Shipping Costs as a Catalyst for Global Inflation

The Covid-19 pandemic has profoundly impacted global supply chains, leading to significant shipment delays and a spike in shipping costs, which have surged by over 150% since December 2023 due to disruptions in maritime traffic in the Red Sea. The study by Yan Carriere-Swallow, Pragyan Deb, Davide Furceri, Daniel Jimenez, and Jonathan David Ostry demonstrates how fluctuations in global shipping costs, measured by the Baltic Dry Index (BDI), contribute to variations in domestic prices across a broad spectrum of countries during 1992-2021.

This article delves into the pivotal role of shipping costs in shaping the global economy, uncovering the mechanisms through which these costs influence inflation and the varying impacts across regions. It also explores strategic approaches to mitigate the escalating shipping costs, underscoring the criticality of shipping in transporting over 80% of the world’s goods and its subtle yet significant influence on global economic activity.

The Role of Shipping Costs in the Global Economy

Impact on Global Supply Chains and Economic Activity

1. The Covid-19 pandemic significantly disrupted global supply chains, increasing shipping costs due to delays and high volumes at ports, which hindered the unloading of cargo.
2. Maritime shipping, crucial to the U.S. supply chain, saw a seven-fold increase in the cost of shipping a container on transoceanic trade routes, affecting 57% of the total value of the average imported good arriving by sea.
3. The global economy experienced a sharp rebound in the second half of 2020, particularly in the manufacturing sector, leading to a strong rise in international orders and supply bottlenecks.

Variability in Recovery and Shipping Costs

1. Global merchandise imports returned to pre-crisis levels by November 2020, though recovery rates varied significantly across countries, with China reaching its pre-crisis level by June 2020.
2. The reliability of global container services declined to record lows, reflecting in rising supplier delivery times and higher container costs.
3. Econometric analysis indicates that initial supply constraints primarily drove the rise in shipping costs, but by the fourth quarter of 2020, the increase was more reflective of a vigorous recovery in global demand.

Shipping Costs and Inflation Dynamics

1. Costs are primarily determined by the balance of supply and demand in the international shipping market. The pandemic-induced demand surge, coupled with a lag in supply, notably affected global shipping prices.
2. Containership earnings soared during the pandemic, which led to an increase in international shipping capacity. However, the construction lag for new containerships, taking two to four years, has temporarily skewed this balance.
3. Higher shipping costs have contributed to consumer price inflation, although the impact varies by region. The European economy, particularly affected by shipping via the Red Sea, shows a minimal contribution of non-EU costs to EU inflation.

Long-term Economic Implications

1. The structural vector autoregressive (SVAR) model suggests that a significant annual increase in shipping costs could raise U.S. Personal Consumption Expenditures (PCE) inflation by up to 0.25 percentage points one year later.
2. As the market adjusts and supply meets heightened demand, freight costs are expected to decline, indicating that the current high shipping costs may not persist long-term.
3. However, the ongoing crisis in the Red Sea and its global ripple effects on freight rates highlight the uncertainty surrounding the future of shipping costs and their economic impact.

Mechanisms Through Which Shipping Costs Affect Inflation

Direct Impact on Import Prices

1. The Baltic Dry Index (BDI) serves as a critical measure, demonstrating that spikes in global shipping costs are directly followed by significant increases in import prices.
2. Research indicates that when the BDI increases, import prices, Producer Price Index (PPI), headline and core inflation, and inflation expectations also rise.
3. This effect is particularly evident during periods of high maritime freight costs, which align with substantial rises in import prices, suggesting a direct correlation between increased costs and import price inflation.

Persistent Inflationary Effects

1. The impact of rising costs on inflation is more enduring than the effects of global oil and food price shocks.
2. Statistical analyses show that the inflationary influence of higher shipping costs peaks after about a year and can last up to 18 months, indicating a persistent inflationary pressure.
3. A new study analyzing data from 143 countries over the past 30 years confirms that shipping costs are a significant, long-term driver of inflation globally.

Comparative Influence on Global Inflation

1. The quantitative effect of shipping cost changes on inflation is similar to that caused by shocks to global oil and food prices.
2. The International Monetary Fund (IMF) estimates that a one standard deviation increase in shipping costs has an inflationary impact comparable to that of a similar increase in oil or food prices.

Differential Impact Across Economies

1. The pass-through effect of costs on inflation varies significantly across different economies, influenced by structural characteristics and the robustness of monetary policy frameworks.
2. Lower-income countries and island states experience more pronounced inflation increases due to higher shipping costs, with island states seeing inflation rates double those of the baseline estimates.

Long-term Projections and Current Events

1. The ongoing war in Ukraine is expected to prolong the elevated global shipping costs and their inflationary effects, potentially keeping them higher for an extended period.
2. Models predict that the surge in shipping costs observed in recent years will continue to significantly influence global inflation rates, with estimated increases in U.S. import price inflation and core goods inflation.

Regional Variations in the Impact of Shipping Costs on Inflation

Differential Impact by Country and Economic Structure

1. Impact on Import-Dependent and Globally Integrated Economies
   • Countries that import a significant portion of their consumption goods and are deeply integrated into global supply chains tend to experience higher inflation rates when costs increase. This is due to the direct pass-through of increased freight costs to consumer prices.
2. Higher Inflation in Landlocked and Low-Income Countries
   • Landlocked nations, low-income countries, and island states typically face higher freight costs. These regions are particularly vulnerable to spikes in shipping costs, often resulting in more pronounced inflationary pressures.
3. Influence of Geopolitical Events
   • Ongoing conflicts, such as the war in Ukraine, are likely to perpetuate disruptions in global supply chains, maintaining elevated costs and their subsequent inflationary effects for an extended period.

Variability in Inflation Response

1. Role of Economic Policies
   • Countries with robust inflation targeting regimes and well-anchored inflation expectations are better positioned to mitigate the inflationary impact of rising shipping costs. These nations often experience less pronounced inflation increases compared to those with less stringent monetary policies.
2. Effect of Domestic Market Size
   • The inflationary impact of increased costs is more muted in countries where imports constitute a smaller portion of domestic consumption. This is due to the limited reliance on imported goods, which reduces the direct effect of global shipping cost fluctuations on the domestic price level.

Potential Long-Term Trends

1. Persistent Inflationary Effects
   • The inflationary influence of higher shipping costs is not immediate but peaks after about a year, maintaining elevated levels for up to 18 months. This prolonged effect underscores the lasting impact that shipping cost fluctuations can have on global inflation.
2. Speculative Concerns
   • Economists express concerns that further disruptions in major maritime trade routes, such as the Suez and Panama canals, could trigger additional inflation surges, compounding the already significant impact of existing supply chain issues.
