NEW YORK, June 11 — The dollar climbed to a near four-week high against a basket of currencies yesterday, after data showed US consumer prices accelerated in May, strengthening expectations the Federal Reserve may have to continue with interest rate hikes through September to combat inflation.

In the 12 months through May, the CPI increased 8.6 per cent after rising 8.3 per cent in April. Economists had hoped that the annual CPI rate peaked in April.

The inflation report was published ahead of an anticipated second 50 basis points rate hike from the Fed next Wednesday. The US central bank is expected to raise its policy interest rate by an additional half a percentage point in July. It has hiked the overnight rate by 75 basis points since March.

“Inflation is now at a 40-year high with little evidence that it has peaked,” said John Doyle, vice president of dealing and trading at Monex USA.

“Stocks are extending losses on the expectation the Fed could find the scope to speed up rate hikes. The greenback is gaining on policy divergence and risk-off trading,” Doyle said.

The US Dollar Currency Index, which tracks the greenback against six other major currencies, was 0.8 per cent higher at 104.16, its highest since May 17, and within sight of 105.01, the two-decade high touched in mid-May.

For the week, the index was up nearly 2 per cent, its best weekly performance in 6 weeks.

The dollar was up 0.79 per cent against the Swiss franc at 0.9881 francs after the US Treasury Department yesterday said Switzerland continued to exceed its thresholds for possible currency manipulation under a 2015 US trade law, but refrained from branding it a currency manipulator.

With the US inflation data knocking investors’ risk appetite, the risk-sensitive Australian dollar reversed direction to trade down 0.58 per cent on the day.

Sterling fell 1.5 per cent to US$1.2315 (RM5.42) and was set for a second consecutive week of declines as Britain’s gloomy economic outlook left investors on edge.

In cryptocurrencies, bitcoin slipped 3.7 per cent to US$28,984.33, as the world’s largest digital currency by market value continued to struggle to overcome a bout of selling pressure that has taken it below the US$30,000 level in recent sessions. — Reuters
