Inward Arbitrage

What Does Inward Arbitrage Mean?
A form of arbitrage involving rearranging a bank's cash by borrowing from the interbank market, and re-depositing the borrowed money locally at a higher interest rate. The bank will make money on the spread between the interest rate on the local currency, and the interest rate on the borrowed currency.

Investopedia explains Inward Arbitrage
Inward arbitrage works because it allows the bank to borrow at a cheaper rate than it could in the local currency market. For example, assume an American bank goes to the Interbank market to borrow at the lower eurodollar rate, and then deposits those eurodollars at a bank within the US. The larger the spread, the more money that can be made.
