Important Data Releases: The U.S., Canada, and Australia, will release their Trade Balance, measuring the difference in value between imported and exported goods and services during the reported month. Export demand and currency demand are directly linked because foreigners must buy the domestic currency to pay for the nation's exports. Export demand also impacts production and prices at domestic manufacturers. Besides trade balance, Canada also has other important data releases. Bank of Canada will release BOC Rate Statement, the primary tool the bank uses to communicate with investors about monetary policy, and will also release Overnight Rate, measuring the interest rate at which major financial institutions borrow and lend overnight funds between themselves. In UK, Services PMI measures the level of a diffusion index based on surveyed purchasing managers in the services industry. Last but not least, in Japan, Bank of Japan will release Monetary Policy Statement.
