Increasing the cost of borrowing decreases economic activity by essentially making everything more expensive on credit. Many businesses use credit facilities to finance ongoing operations throughout the year and their ability to afford to operate their business will go down, requiring them to employ less and attempt less business. This reduces inflation by pulling capital back from growth and investment as well as into savings facilities. But the other side is it induces a recession, increases unemployment, and decreases wages. This is worse than inflation IMO - if you make less money how is that different than things costing more? The supply of money might change the nominal price of something and hurts fixed income folks, but as wages are elastic as well as prices unless inflation is coupled with decreased wages and employment whats the relative difference? Further consumption based economies burn money supply down quickly if the economy is able to meet demand.
By reducing the cost of shipping and improving shipping capacities any excess cash would be consumed by having supply meet demand. That can be achieved by lowering interest rates which stimulates capital investment in supply side expansion and facilitated demand by lowering the marginal cost of credit facilities.
