Yam Prices Explained

Yam export price decreased by -19.4% against the previous month. Its prices this year are relatively flat compared to last year’s record which posted an increase of 31% MoM (month on month).

However, the global yam powder market continuously expands due to steady innovation in the food industry. Moreover, the increasing demand for organic yams adds potential marketability of this commodity.  Thus, this will highly contribute to the marketability of yam and its future price fluctuation in the market.

Why are yam prices fluctuating?

1. Transportation Costs

Transportation expenses have an impact on yam prices since they must be transported from farms to markets quickly and efficiently due to their perishable nature. As a result, wholesalers and retailers charge higher prices to cover extra costs and guarantee profits due to increased transportation costs.

Additionally, fuel prices, distance traveled, road conditions, vehicle maintenance, and market charges are some of those components that affect transportation expenses. For instance, the war between Russia and Ukraine caused a surge in fuel prices which ultimately affected commodity value, including yam prices.

2. Quality and Variety

Yams vary widely in size, shape, color, flavor, texture, and nutritional value; thus, these aspects all affect the price of yams. Consequently, some yam varieties are more popular than others because of how well they work with particular recipes or markets.

For example, ube powder, a starchy ingredient from purple yams is extensively used in sweet baked products, cakes, ice cream, jams, and curries.

3. Weather Conditions

Unfavorable weather events like heat waves, floods, or droughts cause yam quantity and quality to decline, resulting in a yam shortage and higher pricing. On the other hand, yam costs decrease in an environment that supports yam production, such as one with sufficient rainfall, mild temperatures, and rich soil.

The ideal temperature range for yam growth is 25 to 30°C, and it thrives in well-drained fertile soils with a pH between 5.5 and 6.5 in full sun or part shade.
