Hello Daniel, in the last 10 years, the minimum price for 60-count per kilo, head-on, white shrimp in Thailand was $2.46. The maximum price was $8.60, and the average was $4.15.
In any given market, prices often go higher and lower than expected.
When evaluating market prices, we should look at the long-term trend. Our sense of values and prices tends to be short term and can be distorted. It is a mistake to look at the last 24 months. Admittedly, looking back fifty years may also be problematic. I think you have to look at average prices, maybe a moving average, to gain a sense of their range. The price is now $4.91, the 10-year average is $4.15 and the 5-year average is $4.76.
