Quantifying the commodity consumer shock at 5-6 of global GDP its as big as the early 1970s

Ongoing commodity shock is on track to be a similar order of magnitude as the first oil shock in terms of share of global GDP. US commodities consumers will pay ~ $1T more relative to 2019 or -3.4% of US GDP.

Global consumers are projected to pay ~$5.2tn more for commodities in 2022 than in 2019, equating to ~5% of world GDP, with potential to rise to ~$6.3tn or ~6.2% of GDP if 2H'22 prices hold. This shock mirrors the first oil shock's impact on global GDP. The prolonged shock could hinder global growth, with Europe and some emerging markets (EMs) particularly vulnerable. OECD Europe may see a $1.4tn increase in costs, raising commodity consumption to 10.3% of GDP, surpassing the 2000s supercycle peak. In the US, consumers could pay $1tn more, increasing costs to $1.8tn or -3.4% of GDP. The US remains a net energy and agricultural exporter, while Europe is a major net energy importer.

Ephrem Ravi and Krishan M Agarwal, "Quantifying the commodity consumer shock - at ~5-6% of global GDP it’s as big as the early 1970’s,"Citi, June 14, 2022, https://www.citi.com/mss/solutions/citi-research/

Global consumers of commodities are set to pay producers ~$5.2tr more during 2022 than they did in 2019, an increase representing ~5.0% of world GDP, using Citi’s base case 2H’22 forecasts. In the scenario that 2H’22 forward prices materialise, the commodity ‘tax’ paid by consumers would be ~$6.3tr higher than during 2019, equal to ~6.2% of GDP. In either case, the ongoing commodity shock is on track to be a similar order of magnitude as the first oil shock almost 50 years ago, when taken as a share of global GDP.The longer the commodity shock persists, the bigger the negative impact on commodity consumers and on net, global growth and equities. We find that Europe and some EMs growth looks particularly vulnerable, as does € credit, to a higher for longer commodity price scenario, while South American FX should benefit. For OECD Europe, consumers of commodities could pay $1.4tr more during 2022 than they did in 2019, with commodity consumption costs rising to $2.3tr from $0.9tr, representing an increase of -5.9% of OECD Europe GDP, comparing May spot (annualised, to 2019, or using 2H'22 forwards). The value of commodities consumed in Europe is estimated to have been higher during May 2022 (annualised), at 10.3% of GDP, than it was during the peak of the 2000's commodity supercycle period, at 8.2% of GDP.Europe is a major net energy importer. For the US. consumers of commodities could pay $1.0tr more during 2022 than they did in 2019, with commodity consumption costs rising to $1.8tr from $.8tr representing an increase of -3.4% of US GDP, comparing May spot (annualised to 2019)The US is a net energy and agricultural commodity exporter.

Anand Comment:the difference has to be net energy? And, the US could be a much larger net energy exporter if we had the right policies….if we don’t drill, someone else will. Nowhere is this more true than natural gas where the qataris make billions while we ban drilling/fracking in the marcellus (especially NY)

Steve Comment:Yes I think you are largely correct plus one other factor - suspect differences btw our (US versus Europe) corporate sectors both in level of intangible investment btw comps and the size of our relative sectors, ie the mittelstand is a larger share of the German corporate sector than in the US (manufacturing is 18% of value added in 2020 in Germany versus 11% in the US the previous year according to World Bank.)

Choking Iran's Economy Is the Least Bad Way to End the War

Javier Blas Bloomberg

Is Database:: Database

Inflation in Iran is running at at least ~69%, its highest annual rate in 70 years. The black market exchange value of a rial hit a record low of ~1.85mm rials to the dollar, relative to 50,000 per dollar five years ago.

[Iran's] economy is on track to suffer the biggest annual contraction since the nadir of the Iran-Iraq War in the mid-1980s. Inflation is running well above 50%, the highest annual rate since records start nearly 70 years ago. Worse, the cost of food and other necessities has already doubled from a year ago. Its currency, the rial, is worthless. In the black market, the exchange rate has collapsed to a record low of about 1.85 million rials to the dollar; five years ago, roughly 50,000 rials were enough to buy a greenback.

Takeaways by Macro Roundup^® AI

Iran’s inflation rate exceeds 50% annually — the highest in nearly 70 years of records — while food and essential goods costs have doubled year over year, severely compressing household purchasing power across the economy.
Iran’s GDP is on track for its steepest annual contraction since the mid-1980s Iran-Iraq War nadir, a deterioration that surpasses every recessionary episode across four intervening decades.

A Return To Monetarism?

Is Important:: Important

Ireland, Miran, and Roubini compare the actual price level to the predictions of an equilibrium model relating prices to money supply. Predicted inflation hit a 60-year high in 2020–21, months before inflation surged and then crashed once the Fed hiked.

The graphs in Figure 3 show quite clearly how the surge in money growth starting in 2020 and continuing in 2021 put enormous upward pressure on inflation, to a degree unprecedented in the post-1967 sample period. And while the large and negative price gaps that followed in 2022 and 2023 are likewise indicative of strong disinflationary pressures applied through subsequent monetary tightening, one can’t see these graphs without asking: Had Federal Open Market Committee members been monitoring measures of money growth with the help of the P-star [price target based on monetary aggregates] model, might they have ended QE and raised interest rates sooner and more quickly, thereby avoiding at least some of the post-2020 inflation? Of course, massive fiscal expansion was another driver of the post-2020 surge in inflation, as suggested by fiscal theories of the price level. The model simply observes that regardless of its originating source, excessive money growth signals that inappropriate macroeconomic policies are fueling higher inflation. Fiscal expansions that expand money supply will be reflected in a P-star model.

Home Alone: Inflation And The New Fed Chair

Cembalest notes labor market tightness, price pressures in the manufacturing sector and the implied output gap are “much closer to conditions that have historically prompted the Fed to raise policy rates rather than to lower them.”

Inflation indicators the Fed watches include labor market tightness, price pressures in the manufacturing sector, supply chain tightness and the “output gap” which measures how far actual growth is above/below potential growth. [The two] charts plot these four variables at the time of prior Fed decisions to increase or cut policy rates; green dots indicate when the Fed cut, red dots indicate when the Fed tightened and yellow circles show today’s values. In other words: current values are much closer to conditions that have historically prompted the Fed to raise policy rates rather than to lower them. That may be why the futures curve is now pricing in Fed hikes instead of the cuts that were priced in at the start of the year. Superwonky: averaging several different monetary rules of thumb (Taylor rules, inertial, alternative r*, forward-looking) yields a Fed Funds range of 4.00% - 4.85% compared to the current range of 3.50% - 3.75%.

Monetary policy rules average a 4.00–4.85% Fed Funds range vs. the current 3.50–3.75%, indicating tightening bias drives futures pricing toward.
Labor market tightness, manufacturing price pressures, supply chain constraints, and positive output gaps align with historical rate-increase conditions, leading markets.

US Consumer Sentiment Slides to Record Low on Price Concerns

The Michigan Consumer Sentiment Index hit a record low in May, falling ~10% month over month. Consumers foresee prices advancing 4.8% over the next year. Inflation and high gas prices have long been major causes of sentiment drops.

The University of Michigan’s final May sentiment index decreased 5 points to 44.8 from April. The gauge was weaker than all projections in a Bloomberg survey of economists as well as the preliminary reading of 48.2. Consumers expect prices to rise an annualized 3.9% over the next five to 10 years, up from 3.5% in April and the highest in seven months. They also saw costs advancing 4.8% over the next year.

Takeaways by Macro Roundup^® AI

Michigan consumer sentiment fell 5 pts to 44.8, undershooting all economist forecasts, driving heightened recession risk perceptions.
Five-to-10-year inflation expectations surged to 3.9% from 3.5% month-over-month, the highest in seven months, leading to eroded purchasing power confidence.
One-year price expectations of 4.8% vs. 3.9% long-term forecasts signal consumers expect near-term cost acceleration to outpace eventual moderation.

Where Did All the Affordable Cars Go?

Clifford Winston New York Times

Date Posted:: April 15, 2026
Is Database:: Database

In 2012, there were ~12 new cars available for around $25,000 in real terms in the US. Today, there are only 4 new cars available at that price point. Clifford Winston notes allowing Chinese imports would likely increase that number to 11.

The average transaction price for a new car now sits around $50,000. In December, it became just about impossible to find one for less than $20,000. For anyone on a budget, an aging car is a trap. Auto repair costs jumped 15% in the last year alone, driven by the complexity of modern sensors and labor shortages. An average trip to the mechanic now costs roughly $840. To fix the problem, policymakers must overturn what has been for decades the third rail in American politics. It is time to stop coddling Detroit automakers [and open] the American market to cars made in China and elsewhere. Chinese cars aren’t just cheaper than the American alternatives. They’re often better. Take BYD’s slightly more upscale Seal sedan. It’s similar to Tesla’s Model 3, introduced nine years ago. But the Seal costs roughly $20,000 less than the Model 3. The Seal’s premium model offers substantially more horsepower, and its battery not only lasts longer, it can also be 80% charged in just 37 minutes. The Seal isn’t just a budget alternative; it is a more advanced machine.

Takeaways by Macro Roundup^® AI

Average new car prices reached $50,000, up from sub-$20,000 availability a decade ago, driving affordability crisis for budget consumers.
Auto repair costs jumped 15% annually to $840 per visit, as sensor complexity and labor shortages result in escalating ownership.

Inflation Is Down, But Americans Still Feel an Affordability Squeeze

The US price level has risen 26% since January 2020, leaving Americans’ average weekly real wages up only 3.7% over five years.

The average American’s weekly pay has risen 31% over the past six years. That’s faster than prices across that period, so Americans in the aggregate aren’t losing ground — but inflation wiped out most of their income gains. For low earners, who saw the fastest wage growth after the pandemic, the last year or so has been tougher and they’re now lagging behind. [Grocery] prices are up about 30% since January 2020, about in line with average wage growth. But Americans had gotten used to paying roughly the same at the supermarket each week in the pre-pandemic years. Lately, they’ve been forced to stomach a bigger bill with almost every visit. A double-punch has pushed homeownership out of reach for many Americans: First the pandemic-era surge in prices, and then a steep run-up in mortgage rates. A young married couple now needs 70% of their annual household income to afford the average down payment, according to Goldman Sachs economist Elsie Peng, up from 58% in 2019 and 45% in 2000. [Further], the average principal and interest payment has doubled since early 2020, according to the National Association of Realtors. Employee premiums for family health insurance have risen 23% in the past five years to almost $6,900 on average. And more than 20 million people who rely on Affordable Care Act plans face a hike in their premiums after Congress let Covid-era subsidies expire.

Ongoing commodity shock is on track to be a similar order of magnitude as the first oil shock in terms of share of global GDP. US commodities consumers will pay ~ $1T more relative to 2019 or -3.4% of US GDP.

Inflation in Iran is running at at least ~69%, its highest annual rate in 70 years. The black market exchange value of a rial hit a record low of ~1.85mm rials to the dollar, relative to 50,000 per dollar five years ago.
