Royal Bank and TD Canada Trust announced Monday they are increasing several fixed mortgage rates by up to 6/10ths of a percentage point.

The biggest jump is attached to the popular five-year fixed closed rate, which moves from 5.25 per cent to 5.85 per cent at both banks. That's the posted rate, which is routinely discounted by the big banks.

RBC's new discounted rate for the five-year term also rises 6/10ths of a percentage point to 4.59 per cent. TD's rises the same amount to 4.55 per cent.

Both banks also raised their three-year and four-year fixed closed rates. The posted three-year rate at Royal Bank climbs one-fifth of a percentage point to 4.35 per cent, while the posted rate at TD jumps 4/10ths of a point to 4.70 per cent.

The posted four-year rate at both banks jumps 4/10ths of a percentage point to 5.34 per cent.

Other banks are expected to follow suit. The new rates, effective Tuesday, represent the first hike in Canadian mortgage rates since last October. The posted five-year rate is now back to where it was for much of last summer.

New mortgage rules that go into effect next month require borrowers to qualify at the five-year rate, rather than the old three-year standard, even if they are applying for a variable rate mortgage.

Variable mortgage rates, which rise in tandem with the Bank of Canada's key overnight lending rate, are not affected by Monday's announcement. But they are likely to be heading up soon too.

Bank of Canada governor Mark Carney warned last week that inflation was higher than expected. That had some market watchers forecasting that the central bank could move to raise its key lending rate as early as June.

The key rate has been at a rock-bottom 0.25 per cent since April 2009 to help the economy recover.

Fixed-mortgage rates tend to move higher when long-term bond yields rise.

A report out Monday from CIBC World Markets said rising rates shouldn't be enough to derail the stock market rally - pointing out that the market is historically strong six months before and after rate increases.

A survey released last week by RBC found almost two-thirds of respondents expected the cost of servicing a mortgage to rise this year.
