The Chancellor has ruled out several concessions the US is thought to be looking for as the price of a deal.
These include reductions in food standards rules that limit imports of American agricultural goods and changes to online safety legislation that some US politicians believe limit freedom of speech.
A deal could, however, involve a reduction in tariffs on US cars in exchange for a cut in tariffs on British-made vehicles, with Ms Reeves declining to rule out such a move on Wednesday.
So far, the Chancellor has used her visit to the IMF to champion free trade, telling a panel event on Thursday evening she wanted to see both tariff and non-tariff barriers reduced.
