Scott Bessent may rue the day he became US Treasury secretary ...

Scott Bessent seems overjoyed at his nomination for US Treasury secretary. But he’s perhaps being handed a poisoned chalice. When he leaves office, he may rue the day he became the 79th Treasury secretary as the inconsistencies and ill-conceived thrust of President-elect Donald Trump’s economic policies generate huge fallout, catching up with the US and Bessent’s reputation and tenure.

The Treasury secretary is the administration’s chief economic spokesperson, representing the US globally on economic and financial affairs in fora such as the G7, G20, International Monetary Fund and World Bank. Bessent will play a leading role in selling Trump 2.0 policies to Capitol Hill and internationally.

The problems won’t hit immediately but the challenges over time could become overwhelming.

Fiscal profligacy

Foremost, Bessent will be tied to Trump’s fiscal legacy. US debt is high (100% of gross domestic product) and the fiscal trajectory unsustainable. Deficits are already projected at more than 6% of GDP per annum for the next decade. His first fiscal tasks will involve dealing with the debt ceiling and then extending Trump’s 2017 tax cuts.

The Committee for a Responsible Federal Budget estimates Trump’s fiscal plans, if he gets his way, could add a further $8tn to US debt over the coming decade, roughly 2.5% of GDP annually. That amount of issuance may give markets severe bouts of indigestion, pushing up the term premium and slowing growth. Of course, something may crack – will bond vigilantes savagely impose discipline?

Trump’s team will trumpet old canards – tax cuts will boost growth, largely paying for themselves; they will slash spending. Don’t believe the hogwash. Trump has said he won’t touch entitlements, the heart of mandatory spending and two-thirds of the budget. Discretionary spending is largely defence, and that may have to go up. The interest bill is soaring. Spending cuts mean goring somebody’s ox. Bessent runs the risk of presiding over the height of fiscal profligacy. What would Alexander Hamilton say?

The Fed whisperer

The Treasury secretary typically meets privately and often with the Federal Reserve chair. The media is obsessed with whether Trump can or will fire current Chair Jerome Powell. They miss the boat. Trump’s fiscal plans and tariffs will boost interest rates and inflation, slowing how far Fed rate reductions can go.

The Fed may have to temporarily quell episodic market indigestion, but doing so on a lasting basis would border on succumbing to incipient fiscal dominance. If this scenario unfolds, an independent Fed will push back. Trump may revert to hammering the Fed, pressing it perhaps to pursue some form of quantitative easing or yield curve control, catching Bessent in the crosshairs notwithstanding his wrongheaded call for a shadow Fed chair.

Tariffs and sanctions

The Treasury plays a leading role on financial sanctions. It’s a secondary player on trade policy but a long-time voice for liberal trade.

On financial sanctions, will Trump 2.0 be unilateralist or multilateralist? When a unilateralist Trump pulled out of the Iran Joint Comprehensive Plan of Action, Europe lamely responded by seeking to create a payments system bypassing the dollar – the ill-fated Instrument in Support of Trade Exchanges. The mere act showed deep antipathy. President Joe Biden’s administration, especially in its praiseworthy efforts to block Russian central bank and oligarch assets, acted multilaterally. Greater unilateralism would stir the pot between the Treasury secretary and foreign colleagues.

Trump’s proposed 10% across-the-board and 60% on China tariffs will put US protectionism on steroids. Bessent will have to defend Trump’s trade policies, especially to global financial authorities. That will not make him popular.

The dollar

In recent decades, only the secretary of the Treasury spoke on the dollar and said as little as possible. Regardless of whether Bessent reportedly thinks the dollar should be left to float, cacophonous Trump officials have called for ‘devaluation’. Bessent could end up scrapping with Trump’s trade team.

The dollar is already strong and it’s mainly a ‘Made in USA’ story. Dollar appreciation since Trump’s victory underscores that fiscal expansion and tariffs are more likely to drive the dollar up, not down. The dollar may soon approach its 1985 pre-Plaza Accord real trade-weighted peak, associated with significant protectionist pressure.

Note: The Federal Reserve revised its series in 2018, discontinuing its old series and no longer showing a consolidated series going back to 1973. The chart above stitches together the old and new series.

Administration options for devaluing the dollar are limited. Neither jawboning nor intervention are likely to have lasting impact, and a Mar-a-Lago Accord seems infeasible given that an independent Fed targets inflation, not exchange rates, and a weaker dollar might require fiscal consolidation, not expansion. Tariffs, let alone measures to reduce capital inflow, could curb some US bilateral deficits. But the dollar’s reserve currency and global financing role may be weakened, perhaps raising US financing costs. No respectable Treasury secretary should wish to be associated with talking down the dollar, calling for devaluation or undermining its global role.

China

Everybody in Washington is a China hawk. Trump’s selection of national security officials makes clear that talons will be out. The US and Chinese economies account for more than 40% of global GDP. This systemic relationship will most likely become frostier. The Treasury under Secretary Janet Yellen reestablished discussions with Chinese finance authorities, including in bilateral visits and economic and financial dialogues. Neither side was under any delusion that US-China relations were hunky dory. But at least frankness helped limit misunderstandings. Will the Treasury continue these?

Moreover, US fiscal expansion and tariffs should put downward pressure on the renminbi. China may allow the renminbi to slide in response to tariffs, though with restraint, fearing it could trigger a massive one-way selling wave, as happened in 2015-16. Regardless, renminbi weakness on top of large trade surpluses may prompt the White House to instruct the Treasury to designate China for currency manipulation even if the criteria are not met, as happened in 2019, or rekindle ill-conceived Department of Commerce-mandated currency undervaluation countervailing duties.

It isn’t pretty

Bessent may also need to play a role in scuttling the G20-Organisation for Economic Co-operation and Development international tax deal and helping lead the charge on financial market deregulation. These are only a few areas that will be on the incoming secretary’s plate. The challenges will be heroic, fraught with peril. It’s hard to imagine what success looks like. Bessent may rue the day he became the 79th secretary of the Treasury.
