New York (CNN Business) America's business leaders are growing more worried that the United States will enter a recession by the end of 2020. Their primary fear: protectionist trade policy .

That is the topline finding of a report released Monday by the National Association for Business Economics. The survey , based on responses by 53 economists, is a leading barometer of where the US business community thinks the economy is headed.

The report comes as the United States ratchets up its trade war with China and has gone after other major trading partners, including Mexico and India

The risk of recession happening soon remains low but will "rise rapidly" next year. The survey's respondents said the risk of recession starting in 2019 is only 15% but 60% by the end of 2020. About a third of respondents forecast a recession will begin halfway through next year.

According to the survey, the median forecast for gross domestic product growth in the last quarter of 2020 was 1.9%. That would be a big drop from the most recent estimate of current US economic growth — 3.1% in the first three months of 2019

The United States is probably somewhere in the last stages of an epic run of economic growth that began in 2009. Dramatic and coordinated responses by the Federal Reserve, Congress and the Obama administration helped pull the country up from the Great Recession.

President Donald Trump, who took the reins of the US economy from Barack Obama in 2017, has aggressively tried to reorder the US position on global trade. He has picked prominent fights with China and Europe and has threatened tariffs on Mexico over illegal immigration and India over access to its markets.

Other notable findings from the National Association for Business Economics:

-- 56% of respondents cited increasingly protectionist trade policy as the greatest risk to the US economy in 2019. Separately, 88% pointed to US trade policy, and retaliation by other nations , for why they lowered their GDP growth forecasts.

-- 14% believe a "substantial" decline in the stock market, and 10% feel a slowdown in global growth , are the biggest risks to the US economy.

-- Business spending will moderate this year and next after growing a strong 6.9% in 2018.
