Only their Forex relevance marked here.
Generally, it is believed that Forex market impacts these markets. However, it is the actual markets of real products that make the world of foreign (currency) exchange. So I do believe, it is good to know the most important markets:
Beside trade flows, another example is money flow. Ff investors get their money away from NASDAQ, NYSE (Indices of these fall) and away from US dollar, the Forex market gets impacted, dollar falls.
Another example would be a growth in gold and silver investment can signal the fall of US dollar or the currency which is used buying these. People tend to buy gold when they are afraid of value loss of the currency.
A third example would be futures and options on currencies. Companies use these financial products to hedge against currency exposure. Growth interest in such products signals uncertainity about the future of a certain currency.
