Market price (spot, bank, over-the-counter exchange rate):

• It is the value at which dollars are actually bought and sold in banks, exchange houses or financial platformsand may differ between institutions.
• This price varies constantly during the day according to supply and demand, economic expectations, monetary policy, news, and international factors.
