The Benefits of a Weak Dollar Despite expressions to the contrary by politicos and economists, the nature of a weak dollar can actually benefit stagnated portions of our economy. For example, a weak U.S. dollar will actually help boost the manufacturing sector. A weak dollar can also help sell U.S. made goods in overseas markets at lower prices. A weak dollar will benefit a few European retailers who import Asian products bought for dollars and sell them in European markets for stronger euro payments.
