Stock markets swoon as reality of rising rates sets in

The TSX and Dow Joneswere sharply lower on Wednesday as fears of higher interest rates to come took the wind out of the sails that have poweredstock market returns for years.

The Toronto Stock Exchange closed down 336 points, or more than two per cent, on Wednesday, the fourth day in a row that the benchmark Canadian stock index was lower.

Every subsectoron the TSXwas lower, from the banks, to energy, to health care names, retailers and other consumer staples.

Oil prices were lower, with the U.S. benchmark West Texas Intermediate losing almost $2 to trade at just over $73 US a barrel. Canadian crude oil, known as Western Canada Select, is even cheaper, at barely over $26 US a barrel. That puts the gap between the two oil prices at its highest level on record, which is weighing heavily on shares ofCanadian oil companies.

"There's just no demand for this heavier Canadian crude, and you can't get it to refineries" says John Zechner, chairman of Toronto-based money manager J. Zechner Associates.

In the U.S. the losses were even steeper.The Dow Jones Industrial Average was off by 818points when markets closed, or more than three per cent. The broader S&P 500 was down by even more, and had its worst day in more than six months.

The technology-focused Nasdaq fared worst of all, losing more than four per cent. A lot of that was because of theso-calledFAANGstockstechnology names such as Facebook, Amazon, Apple, Netflix and Google flyinginto turbulence on Wednesday.

"As stocks go up, tech goes up more than the stock market," said Gina Martin Adams,chief equity strategist for Bloomberg Intelligence. "As stocks go down, tech goes down more."

The catalyst for all the gloom is the prospect of higher lending rates. The U.S. central bank hiked its rate at the end of September, and Canada is expected to follow suit at the end of the month.

Fear over higher rates is being best expressed in the bond market where prices have slidlower for weeks.Higher rates makecurrent bonds less attractive than future ones, which will come with higher yields. It's alsobad news for stocks as that means it willget more expensive to borrow money to invest.

Market watchers have been expecting yields to start slowly moving, but it seems to have caught some off guard.

"Investors missing this rate move is tantamount to letting yourself get run over by a glacier," saidMike Terwilliger, portfolio manager of Resource Liquid Alternatives for the Resource Credit Income Fund in New York.

Zechner says after booming for so long, stock markets tend not to riseforever and markets historically correct before the broader economy does.

"Rising interest rates in the U.S. ... are suddenly becoming much more of a concern and people are paying attention," he said.

He notes that while the U.S. stock market has managed to post gains virtually uninterrupted, that's not the case in most other parts of the world, so that trend may be finally catching up in North America.

"We're seeing cracks in the armour[and] to me it'snot why that happened," he said.

"It'swhy hasn't it happened sooner than this."
