Officials from Taiwan’s central bank have rejected the implication of currency undervaluation in a chart used by Ben Bernanke. The offending graph – to the right – shows changes in the real effective exchange rate on its vertical (y) axis. Taiwan’s currency weakened by 2.8 per cent in real terms between September 2009 and 2010, according to this Fed chart. Taiwan says it fell by just 0.2 per cent, and argues that REER is not a good measure of undervaluation anyway.
At stake is responsibility for volatile capital flows that add to inflation in emerging markets and threaten to destabilise recovery. Emerging markets point to the Fed’s stimulus programme. But Mr Bernanke argued in his speech that the Fed’s $600bn stimulus programme was good for the world economy, refusing to accept responsibility for the extra inflationary pressure flowing through to emerging markets. In spite of former chair Alan Greenspan’s comments to the contrary, the Fed also continues to deny any attempt deliberately to weaken the dollar.
Indeed, Mr Bernanke accused emerging market economies of spending their reserves to slow the appreciation of their currencies. Hot money, he argued, was flowing into emerging markets regardless of Fed actions, because investors expected currencies they were buying to strengthen further. Since – by this chart – Taiwan’s currency has strengthened the least (indeed, has weakened), the implication is that Taiwan is one of the worst ‘offenders’. Read more
