Gold prices rose to a two-week high amid continuing concerns about U.S. tariff plans. In addition, the markets' attention is focused on the Fed's decision on the interest rate and the comments of Chairman Jerome Powell, scheduled for Wednesday. Trading participants want to get signals about the future course of the US central bank.The high level of uncertainty is caused by disagreements about the vision of the future of monetary policy. Since December last year, the Jerome Powell-led Fed Funds rate has been kept in the range of 4.25-4.50%. At the same time, US President Donald Trump is pushing for a key rate cut and has already raised the issue of stepping down as head of the Fed, although he later denied such an intention. Risks of interference in the activities of the regulator additionally increase the level of uncertainty in the markets.Any hints of easing the policy of the Federal Reserve can further support gold, strengthening the upward momentum.Technically, the growth of the price began from the zone of $3220. If the market manages to stay above $3350, there is a probability of growth continuation. However, until clarification of the situation on Wednesday, investors and traders are likely to remain in a state of uncertainty.
