Some members of the US Federal Reserve are already considering reversing its plan to gradually raise interest rates this year, just two months after raising them for the first time in several years.
Minutes from the Fed's latest meetings show that some members are concerned about how the global economic landscape could impact the US economy.
The country's central bank raised interest rates from 0.25% to 0.5% in December, having voted unanimously in favour of the decision, with the intention of continuing the slight increases throughout 2016.
The minutes said: "Members observed that if the recent tightening of global financial conditions was sustained, it could be a factor amplifying downside risks."
Although the Fed said it was too early to say whether or not the global economy would adversely effect the US economy, it agreed to monitor the situation closely.
Last week, the Federal Reserve's chair, Janet Yellen, told Congress that the slowdown seen particularly in China could "drag on the US economy". Economists are concerned about the impact China's economic problems would have on the likes of Mexico and Canada, two of the US' biggest trading partners.
