Since the $500,000 is withdrawn from a deposit-taking company, M3 will decrease by $500,000 and M1 will increase by $500,000 immediately. Also, M2 will increase by $300,000 and M1 will decrease by $300,000 after depositing the money as a time deposit. M1 will decrease by $200,000 after remitting the money overseas.
The net change on
M1: +$500,000 (withdrawal) - $300,000 (time deposit) - $200,000 (remittance overseas) = $0;
M2: +$300,000 (time deposit) + $0 (net change in M1) = $300,000
M3: -$500,000 (withdrawal) + $300,000 (net change in M2) = -$200,000
