* IMF cuts 2018, 2019 global growth view on Sino-U.S. trade war
* Says U.S., China to feel effects only in 2019
* Treasury yields near 7-1/2-yr highs, weigh on stocks

Oct 9 (Reuters) - U.S. stock index futures pointed to a lower opening on Tuesday, following European and Asian weakness, after the International Monetary Fund cut its global growth forecasts, squarely blaming the Sino-U.S. trade war.
The IMF lowered its global economic growth forecasts for 2018 and 2019, and its 2019 estimates for the United States and China, saying the two countries would feel most of the impact of their trade war next year.
"IMF's downgrade just goes to show how the tariff dispute between U.S. and China is beginning to take its toll on the global economy," said Peter Cardillo, chief market economist at Spartan Capital Securities in New York.
Besides the fear of slowing global growth, Wall Street has come under recent pressure after Treasury yields hit multi-year highs as strong data fueled fears about rising inflation and potentially faster interest rate hikes.
The benchmark U.S. 10-year Treasury yield climbed to its highest since May 2011 on Tuesday.
Despite the recent pullback, U.S. stocks are near record highs and that has raised concerns over valuations, especially of high-growth stocks, such as technology and the FAANG group.
"A catalyst like earnings will give investors something to look forward to but right now it's just a continuation of negative news for equities, with higher yields and slowing global growth," Cardillo said.
Shares of the so-called FAANGs Facebook, Amazon , Apple, Netflix and Alphabet were down between 0.52 percent and 1.44 percent in trading before the bell.
