In the past ten years, stimulated by the hiking demand for nuts, the US farms have been increasing the planting of almonds and walnuts. At present, the trees are fruited but under the influence of the trading war between China and the US and the COVID-19, the export of the US has been affected significantly, lading to the price diving.

The United States is the world's largest producer and exporter of nuts such as almonds, walnuts and pecans, exporting more than half of its output with an trading amount of more than 9.5 billion USDs. Although the demand for healthy snack is higher globally, the situation for the nuts of the US is not as good as expected. Export prices for almonds, America's most important nut crop, are reduced by about 25% from over the previous year, according to estimates by Labo Bank. Other nuts have also witnessed similar reduction.
