The U.S. dollar gained slightly against its major rivals on Tuesday, as expectations for stronger economic growth and higher interest rates continued to support the domestic currency.

The dollar has been on a tear in recent weeks, rising more than 5% since Donald Trump’s unexpected U.S. presidential election victory. The rise has taken the U.S. dollar index to its highest level since 2002, a level it continues to trade around.

The greenback’s uptrend appeared intact on Tuesday, although given the size of the recent move, many market participants may be awaiting tangible and detailed economic policies from the Trump administration before pushing the dollar decisively higher.

The final trading week of the year is typically a quiet one for the currency market, with lower liquidity and few expected news events — such as central bank comments — that typically drive market direction.

The U.S. dollar index DXY, +0.04% , which measures the currency against a half-dozen major rivals, rose less than 0.1% to 103.03 on Tuesday. The WSJ Dollar Index BUXX, +0.11% , which measures the dollar against a larger basket of currencies, rose 0.2% to 93.38.

Some market participants are also paying attention to any comments from President-elect Trump on the dollar’s recent ascent because the currency’s strength damages the competitiveness of U.S.-based manufacturers. Any comments from him expressing concerns about the dollar’s rise could trigger a selloff, although that scenario doesn’t appear imminent.
