The US Dollar Index (DXY), which measures the value of the US Dollar (USD) against six major currencies, is losing ground and trading around 99.50 during the Asian hours on Monday. The Greenback declines on fading safe-haven demand following reports that the United States (US) and Iran reached a deal to end their conflict, easing concerns about inflation and higher interest rates.
Washington and Tehran said on Sunday that they have reached an agreement that will take effect on Friday. US President Donald Trump stated that the US is lifting its naval blockade on Iranian ports and that the Strait of Hormuz will reopen after the agreement is signed.
The United Kingdom (UK), France, Germany and Italy said that the countries were prepared to lift sanctions on Iran in response to steps on its nuclear program after the US and Iran reached a deal to end their war.
Iran's National Security Council confirmed a ceasefire agreement with the US, adding that final deal talks will start after the other party fulfills commitments under the memorandum of understanding. Iranian officials said the maritime blockade against Iran should end immediately and entirely.
The CME FedWatch tool indicates that the markets are pricing in nearly a 27% probability of a US Federal Reserve (Fed) interest rate hike in December this year after the peace deal, down from 40% a week ago.
US Dollar FAQs
The US Dollar (USD) is the official currency of the United States of America, and the ‘de facto’ currency of a significant number of other countries where it is found in circulation alongside local notes. It is the most heavily traded currency in the world, accounting for over 88% of all global foreign exchange turnover, or an average of $6.6 trillion in transactions per day, according to data from 2022. Following the second world war, the USD took over from the British Pound as the world’s reserve currency. For most of its history, the US Dollar was backed by Gold, until the Bretton Woods Agreement in 1971 when the Gold Standard went away.
The most important single factor impacting on the value of the US Dollar is monetary policy, which is shaped by the Federal Reserve (Fed). The Fed has two mandates: to achieve price stability (control inflation) and foster full employment. Its primary tool to achieve these two goals is by adjusting interest rates. When prices are rising too quickly and inflation is above the Fed’s 2% target, the Fed will raise rates, which helps the USD value. When inflation falls below 2% or the Unemployment Rate is too high, the Fed may lower interest rates, which weighs on the Greenback.
In extreme situations, the Federal Reserve can also print more Dollars and enact quantitative easing (QE). QE is the process by which the Fed substantially increases the flow of credit in a stuck financial system. It is a non-standard policy measure used when credit has dried up because banks will not lend to each other (out of the fear of counterparty default). It is a last resort when simply lowering interest rates is unlikely to achieve the necessary result. It was the Fed’s weapon of choice to combat the credit crunch that occurred during the Great Financial Crisis in 2008. It involves the Fed printing more Dollars and using them to buy US government bonds predominantly from financial institutions. QE usually leads to a weaker US Dollar.
Quantitative tightening (QT) is the reverse process whereby the Federal Reserve stops buying bonds from financial institutions and does not reinvest the principal from the bonds it holds maturing in new purchases. It is usually positive for the US Dollar.
