Chart 1: USD-MYR's weekly chart as at Oct 24, 2017 (Source: Investing.com)
The stability in the USD-MYR exchange rate belied the strengthening of MYR. The stability of USD-MYR is due to a rebound in the US Dollar Index. That index, which is moving within an expanding triangle, has recently tested the lower line and is now recovering. See Chart 2 below.

A better indication of the strengthening of MYR is shown by the potential breakdown of the uptrend of SGD-MYR exchange rate. From the chart below, we can see that SGD-MYR is trading just below the uptrend line at 3.15.

If MYR continues to strengthen against SGD - especially if it goes below the 3.10 level - we may soon see a trend reversal. Weak MYR has been a boon for exporters and a loss for importers. That may soon change.
