Outward Arbitrage

What Does Outward Arbitrage Mean?
A form of arbitrage involving the rearrangement of a bank's cash by taking its local currency and depositing it into eurobanks. The interest rate will be higher in the interbank market, which will enable the bank to earn more on the interest it receives for the use of its cash.

Investopedia explains Outward Arbitrage
Outward arbitrage works because it allows the bank to lend for more abroad then it could in the local market. For example, assume an American bank goes to the interbank market to lend at the higher eurodollar rate. Money will be shifted from an American bank's branch within the U.S. to a branch located outside of the U.S. The bank will earn revenues on the spread between the two interest rates. The larger the spread, the more will be made.
