Alternatives to holding reserve funds in savings account?

[James Sea]

Are there alternatives out there to holding reserve funds in a savings account? Short term bonds? GICs? Anything else? It hurts me to see essentially nothing in interest on my reserve funds when I know there are better savings strategies, but I'm not sure if there are better moves that also maintain sufficient liquidity. Any charge that would eat up reserve funds would either come in the form of an invoice or go on a credit card to be expensed so I can't imagine needing "immediate" access to funds. Thanks for your thoughts!
