Sharecast - "This will be the last day of relative calm in markets, ahead of two days packed with big central bank action," said FX strategist Francesco Pesole at ING Bank.
The UK benchmark index was flat at 7,657 by the midday mark, with US stock futures struggling for direction in pre-market trading on Wall Street.
Policymakers at the Federal Reserve are due to announce their interest-rate decision on Wednesday afternoon in the US. While they are widely expected to keep rates unchanged, given recent data showing a slight cooling of the US economy, markets will be on the lookout for any indication of future monetary policy.
The Bank of England will follow suit on Thursday, and is predicted to hike rates a further 25 basis points to 5.5%, though it remains to be seen whether this will be the peak for rates in the current cycle. Consumer price index data out on Wednesday will be closely watched, and any upside surprise could reignite fears of rates staying higher for longer.
The recent surge in oil prices is a big cause for concern for policymakers, with inflation still trending substantially higher than their targets. Brent crude was up 0.4% at $94.79 a barrel on Tuesday, touching an intraday high of $95.33 as it nears its 52-week high of $99.56, following a near-30% jump over the past three months.
In economic data on Tuesday, the annual rate of Eurozone inflation unexpectedly eased to 5.2% in August, from 5.3% in July. The new reading was revised from an earlier 'flash' estimate of 5.3%.
