Plot between January 2009 and January 2013 a measure of BoJ intervention (FRED code: JPINTDUSDJPY). Do positive values of intervention indicator reflect purchases or sales of yen by the BoJ? What was the BoJ's policy objective? To investigate whether the intervention was effective, add the U.S. dollar-Japanese yen exchange rate (FRED code: EXJPUS) to the chart, but scaled on the right axis. (LO5)
