RPT-COLUMN-Stirring ingredients of 1985's dollar-capping Plaza Accord: Mike Dolan

(Repeats with no changes)

LONDON, May 11 (Reuters) - There's a familiar air of 1985 about - and not just in Cold War politics or the gull-wing DeLoreans in "Back to the Future".

With inflation rates as high as those of the early 1980s, U.S. interest rates rising faster than those of other major economies and the dollar rocketing worldwide, it's not surprising to see investors making references to 1985's "Plaza Accord".

Named after the New York hotel where finance chiefs of the then G5 world powers agreed to weaken a super-charged dollar through market intervention, Plaza became an iconic moment in economic cooperation of the post-1973 floating currency era.

Borne of divergent monetary policies and Federal Reserve chief Paul Volcker's resolve to finally stamp out double-digit inflation from the 1970s oil shocks, the extreme dollar strength that ensued proved destabilising for U.S. exporters and inflationary for U.S. trading partners. The G5 resolved to correct the overshoot.

It was so successful in pushing the dollar lower against the German mark, Japanese yen, French franc and British pound, that the Western powers were forced to reverse tack in Paris two years later and shore up the greenback.

With Fed tightening back in overdrive after the pandemic as long-dormant inflation rages at its highest since 1982, the dollar's index hit 20-year highs this month - gaining some 16% in a year and more than 30% over the past eight years.

There's good reason for anxiety. So crucial is the dollar still to world financing, commodity pricing and trade invoicing that extreme dollar strength tends to feed off itself - with a rising dollar exaggerating global financial stress as well as acting as both a haven from and a hedge against the disruption.

What's more, the dollar is approaching what Cazenove Capital chief investment officer Caspar Rock calls "emotive levels" - even if the resulting financial stress is probably not yet extreme enough for international action.

Euro/dollar is less than 5% from parity last seen 20 years ago. Sterling is just 7% from pandemic lows against the dollar, below which 1985 levels hove into view. And dollar/yen is above 130 for the first time in 20 years, albeit still half the rate it was in the mid-80s.

While the Fed might welcome a stronger dollar in its battle against 8%-plus inflation, European countries more dependent on energy imports and closer to Ukraine-related supply shocks can only see a stronger dollar exaggerating their cost-of-living squeeze. Japan will balk at the oil import bills too.
