[Note: The following post was originally published on May 18, 2010. Recently, TD Waterhouse started offering only TD Bank High Interest Savings accounts to its clients. Therefore, I've updated and somewhat revised this post to make it current. Feel free to have it bookmarked.]

In response to yesterday’s post on the Renaissance High Interest Savings Account (ATL5000), reader Joseph pointed out that a number of savings accounts are available through discount brokers. These accounts typically pay much better interest than money market funds and may be ideal for parking cash in RRSP accounts. A note of caution: first check with your broker that no fees of any kind are charged for purchasing, selling or redeeming these funds early. I wrote about the Altamira Cash Performer account many years back and the biggest knock then was the steep redemption fees and penalties charged on these funds.

The savings accounts offered through discount brokers have one huge advantage over high interest savings accounts offered by online banks such as Ally or ING Direct. Since the trades executed settle in T+1 day, these accounts offer an ideal way to temporarily park your cash in RRSP, TFSA and taxable accounts and have it readily available for your trades. In contrast, online banks are not practical for registered accounts and it may take 3-4 business days to transfer money from (or to) an online bank to (or from) taxable brokerage accounts. These savings accounts are also a much better alternative to traditional money market accounts because they pay a much higher interest rate. For example, as of this writing, the TD Canadian Money Market Fund sports an yield of 0.38% which is much less than the 1.25% yield of high interest savings accounts.
