A new round of uncertainty triggered a reaction on currency and debt markets: rumors about the possible resignation of US Fed chief Jerome Powell triggered a drop in the dollar and yields. Donald Trump later denied plans to fire Powell, but confirmed that he had discussed it with Republicans and "does not rule out" the scenario of leaving.It seems that markets will continue to face increased volatility for reasons related to the political backdrop.The dollar exchange rate came under pressure: the dollar index declined by 0.33% overnight, and the USD/JPY pair showed a rapid decline from the area we wrote about earlier (149.00-150.00). This range remains relevant as a potential resistance zone.
