The chairman of the Federal Reserve, Kevin Warsh, has insinuated without much specificity that there could be interest rate hikes. Not wanting to give too many clues about his future actions and advocating for a "more discreet" central bank, he admitted that controlling inflation will be a priority, during his intervention at the meeting of central bankers, politicians and academics held in Jackson Hole, Wyoming, USA.

What makes a meeting in a valley in the state of Wyoming, in an idyllic setting, so important? What makes the markets so focused on this annual gathering organized by the Federal Reserve Bank of Kansas City under the protection of the Rocky Mountains, which begins today, Thursday, and ends on Saturday? Interest during these August dates is always high, because this conclave is attended by central bank governors from the world's leading countries, along with finance ministers and business leaders. This is not surprising, because many pragmatic issues, such as whether mortgages will become more or less expensive and whether there will be more or less credit to invest in, depend on what is discussed at this meeting without ties and in a relaxed and discreet atmosphere, not only in the US but globally.
