The New Taiwan dollar extended its strength in Tuesday morning trading, rising above NT$30.00 again, as investors ignored the central bank's latest measures to limit foreign exchange derivative positions to slow down the pace of appreciation, dealers said. At 11:45 a.m., the Taiwan dollar stood at NT$29.464 against the U.S. dollar, compared with Monday's close of NT$30.425. The central bank announced on Monday that the ceiling on banks' holdings of Taiwan dollar non-deliverable forwards and options would be lowered to 20 percent of their total positions, down from the previous one-third, effective immediately. The central bank said the move was aimed at maintaining trading order in the foreign exchange market and curbing market speculation. Despite the measures, demand for the Taiwan dollar remained strong, in particular from exporters as the year comes to an end. Foreign institutional investors also continued to move funds into the local market, betting the local currency would continue to ride the wave of fund inflows as the United States pumps money into the market to boost its economy. Expectations are high that the central bank will raise its key interest rates in its quarterly policy-making meeting scheduled for Thursday, dealers said, and higher local interest rates would also attract more foreign funds, they believed. Dealers said the central bank was very likely to intervene in the local foreign exchange market again in late trading to push the U.S. dollar back to the NT$30.00 level against the Taiwan dollar, a level the market believes the central bank can tolerate in the short term. Since the end of August, the Taiwan dollar has risen 5.22 percent against the U.S. dollar based on closing prices, but by 8.1 percent if actual rates during trading sessions or available at banks, which are now around NT$29.5 to the greenback, are considered.
