Dollar drops as optimism spreads before Fed and BoE decisions

The US dollar sank from a one-week high against a basket of major peers on Tuesday as the mood in financial markets brightened ahead of key Federal Reserve and Bank of England (BoE) meetings this week.

The Fed is widely expected to raise its benchmark rate by 75 basis points (bps) on Wednesday, its fourth such increase in a row. But for the December meeting, futures markets are split on the odds of a 75- or 50-bps increase.

Over in Britain, the BoE is also expected to raise rates by an outsized 75 bps on Thursday before slowing back down to hike by 50 bps in December, reported Reuters.

The US dollar index - which measures the greenback against six rivals, including the euro, sterling and yen - sagged 0.48% to 111.02 on Tuesday. That ate away some of the 0.79% gains it made on Monday.

"The feeling is maybe the Fed will tone down the magnitude of hikes, but certainly the message will be the job is not yet done, inflation remains well entrenched," said Rodrigo Catril, a currency strategist at National Australia Bank.

"Our general sense is that the dollar probably has peaked, but that doesn't necessarily mean it's coming down."

Sterling rose 0.55% to $1.1529 as traders awaited the BoE meeting, after dropping more than 1% on Monday. The euro rallied 0.47% to $0.9923.

The dollar index has surged more than 15% this year as the Fed has hiked rates hard, crushing other currencies and heaping pressure on the global economy.

Investors have become highly sensitive to any signs the Fed and other major central banks could alleviate the pain by slowing down rate hikes.

However, markets were reminded that inflation remains stubbornly high in developed economies on Monday when data showed euro zone prices surged by the most on record in the year through October.

The risk-sensitive Australian and New Zealand dollars rose from one-week lows amid a broad lift in market sentiment.
