SIGNIFICANT CHANGES OCCURRING EVEN OVER A SINGLE SESSION LED TO DAILY LIMIT ADJUSTMENTS
The commodities markets have been showing high volatility in recent months, with significant changes in a single session, from one day to the other, in weekly and monthly comparisons.
Notably, the volatility currently registered is still not close to that observed around 2008.
Soybean, corn and wheat

The coronavirus pandemic starting in 2020 resulted in disrupted supply chains, a race for commodities such as wheat, and concerns about demand worldwide amidst social isolation measures to prevent/decrease the spread of the disease.

This scenario impacted commodity prices in the face of the pandemic's uncertainty. The measures to combat the disease varied between countries, and after the first few months, the pressure to relax social isolation increased, and by the end of 2020, vaccines became available. With this, 2021 began more optimistically, with fewer restrictive measures in most parts of the world and a more significant recovery in economic activity. 

Central banks moved to stimulate the economy by reducing interest rates and adopting monetary easing measures. However, this greater availability of money, stimulating demand, was not accompanied by a proportional expansion of supply, a situation that supported the prices of many products, including commodities, in addition to the imbalance in the logistics chains, such as the crisis of the lack of containers in important global cargo hubs, which ended up being poorly distributed around the world. 

With this, a scenario of higher price inflation was created, as the monetary authorities retreated from their expansionary measures and started to raise interest rates, which, as a result, has fueled the possibility of a recession.

Added to the macro context, 2022 started with the heightening of geopolitical tensions, with the invasion of Ukraine by Russia. This situation brought price spikes for corn and wheat since Ukrainian corn has great weight in the export market and wheat from the two countries directly involved in the conflict. As for soybeans, prices also reacted, but in a more moderate way, since the war's reflexes are indirect, through the vegetable oil market, since Ukraine and Russia are the main players in the world's sunflower market.

Currently, there are doubts about the size of Ukrainian production in 2022/23, and an agreement has been formed to allow the country's grain to flow through the Black Sea, whose ports have been blocked by Russian forces. However, there are still many doubts about the volumes to be exported.

Another point that has also moved prices is the new US crop. At first, a larger acreage was estimated for soybeans than corn as corn has higher production costs and the inputs were also expensive. Then there were delays in the country's spring planting as the lowland areas, where wheat is grown, faced drier conditions.

More recently, the USDA reported that soybean acreage is expected to be lower than corn acreage, and drier and warmer weather in the Midwest is on the radar, contributing to price volatility in recent weeks, and should continue to be seen in the coming months.

Besides this, the 2022/23 soybean planting starting in September and summer corn planting starting in October in Brazil should bring another point of attention to the market. Thus, the weather in the coming months will be of great importance for the performance of the new Brazilian crop and will be another element that will bring price volatility. On August 1, StoneX will release its first estimates for 2022/23 soybean and corn summer crops.

Cotton

Cotton has undergone major turbulence in recent weeks, moving from historically high quotes to a sharply lower trend, which managed, in just three weeks, to bring down the value of futures by up to 30%. However, causes related to traditional fundamentals, such as supply and demand, have played a secondary role in explaining the recent fluctuations due to the large participation of speculative agents in the market during the 2021/22 cycle. 

The cotton prices trend has suffered major inflections in recent years. In 2020, with the pandemic and lockdowns, the textile sector was severely affected, destroying part of the cotton demand that year. Most goods derived from natural fiber are considered non-essential and more income sensitive. In other words, in times of crisis, families prefer to postpone the consumption of second necessities in favor of essential goods. In addition, with the limited movement of people, the physical commerce of clothing, for example, decreased, which further harmed the cotton market. With supply exceeding demand, producer prices and profitability sank, contributing to a drop in production for the next cycle. However, with government aid and income transfer policies, as well as the resumption of people movement after vaccines at the beginning of 2021, the demand for cotton goods began to grow again, encountering lower supply, which supported prices.

Since then, the upward trajectory of prices has encountered few negative sessions, attracting funds and other speculative investors, especially because of the dynamics of on-call positions. Thus, these agents entered the market massively: the strategy consisted in holding the long positions and selling them to the guarantors near contract expiration, when the market becomes less liquid and buying pressure supports prices. Thus, contract after contract of the 2021/22 cycle, prices went on a new upward trajectory, reaching their peak in May this year, when the N22 reached USD 158.2/lb. 

The good times ended as the world economy began to show signs of stagflation in 2022 and 2023. The movement in the financial market in June affected several assets, especially agricultural commodities, as investors sought safer sources of income amidst pessimistic expectations. Since then, cotton has suffered from a significant exodus of these speculative agents, which has put pressure on prices. In July, the December/22 contract reached US¢ 83.22/lp, a drop of 47.4% from the year's high. Thus, while this movement does not stop, it is likely that cotton will continue to decline and lose the gains of recent years.

Vegetable Oils

Also following the global macroeconomic context and accentuated by several market internal ups and downs, the vegetable oil complex has experienced great volatility over the last six months, alternating between a strong and steady pace of increase, which lasted since 2021, and an intense sequence of corrections, which started in June/22.

Fueled initially by the resumption of food consumption and as a feedstock in biofuels production, after the impacts caused by the pandemic, vegetable oil prices led the increases among the main food categories over the last two years, according to the FAO/UN food price index. However, after soybean and palm oil prices jumped about 35% over the past year, driven by factors such as rising biodiesel mandates in major consuming countries and production problems observed in palm oil crops in Malaysia and canola in Canada, in early 2022, the upward momentum intensified. 

In the first five months of this year, new bullish factors were seen in the vegetable oil market and boosted prices. The war in Ukraine limited the global supply of sunflower oil, the world's 4th most consumed oil. Soon after, another big boost came in May when Indonesia, the largest palm oil-producing country, decided to ban exports for about a month, seeking to protect the domestic market from inflation amidst palm prices experiencing record highs in the period. The measure did not work out and resulted in great dissatisfaction among palm producers in the country, whose stocks reached full capacity and production had to be halted due to lack of available storage. 

In June, the Indonesian government re-cleared exports and a stimulus package for palm oil shipments in the country to relieve the high oil stocks, such as removing export taxes until the end of August. Thus, since the start of Indonesia's export release, the international market has been flooded with a large quantity of palm available on the spot market, although demand for the product has remained weak due to the high price levels that the ban had driven foreign buyers.

Between the beginning of June and July 25, the palm oil price on the Bursa Exchange retreated 42% on the nearby contract, returning to the lowest price in 1 year. In other words, palm oil has experienced a historical high and an annual low in about two months. 

Following the palm oil downturns in Southeast Asia, the soybean oil market in South America has also been marked by high volatility over the past few months. The Chicago soybean oil nearby contract reached an all-time high in May this year and has dropped by 30% since then.

Perspective: Mid-Day Commentary for August 7

August 7 – Stocks are looking to end a strong week on a strong note, with the major indexes all in the green at the time of writing. The VIX touched a nearly seven-month low earlier in the session and remains muted as it hovers just below the 15-mark as this morning’s ugly labor market data helps ease hawkish Fed jitters. The dollar has rebounded from its nearly two-month low earlier in the session but remains in the red on the day, trading at 99.55 at the time of writing. Treasuries have had a very volatile day, with yields tanking following this morning’s Non-Farm Payrolls release but bouncing back into midday, with 30-year yields now trading at 5.209%, 10-year yields trading at 4.654%, and 2-year yields trading at 4.204%. Crude oil has risen from the morning lows as traders eye the weekend market closure for potential geopolitical developments, with nearby WTI now down only 0.2% on the day to trade around $78.10 and nearby Brent breaking into the green, up 1.25% on the day to trade above $83.50. The ags are largely mixed, with the grains and oilseeds mostly in the green, save for a mixed picture in the soy complex, while live and feeder cattle futures move in opposite directions, with the former adding to yesterday’s sharp losses and the latter attempting a rebound.

Perspective: Morning Commentary for August 7

August 7 – The U.S. economy unexpectedly lost 23k jobs in July, dramatically below market expectations of an 80k increase and marking the worst Non-Farm Payrolls print since February. Furthermore, May and June were both revised sharply downward, with combined revisions showing 103k fewer jobs than previously reported. Outside of the healthcare sector, which added 22k jobs in July, the losses were very broad-based. Government payrolls saw the largest decline, shedding 53k jobs in July, the largest seen since October 2025, while June was revised down to show a loss of 10k jobs as well. The private sector at least saw growth, adding 30k jobs in July, now matching the month prior after it was revised down from the 49k initially reported, and substantially missing forecasts of 78k jobs being added. This is a sharp reversal in course from the largely better than expected U.S. labor data seen earlier this week.
