President Trump needs a stable dollar along with tax cuts to maximize growth

Lawrence Kudlow on

If you look at periods of dollar weakness, especially the 1970s but also the 2000s, a sinking dollar is usually associated with rising inflation, higher interest rates and damage to the economy. In these circumstances, investors at home and abroad lose confidence and take their money elsewhere.

President George W. Bush's pro-growth tax cuts were partly nullified by a sinking dollar. Yet when Presidents John F. Kennedy and Ronald Reagan slashed marginal tax rates, they also favored a sound dollar. (I covered this at length with Brian Domitrovic in our book, "JFK and the Reagan Revolution.") Low taxes and a stable dollar was a winning combination that promoted economic growth without inflation.

There's a lesson to be learned here. But we haven't really seen the Fed reference the dollar for many years. It seems not to be part of its flawed and outdated economic models.

By the way, it's not just the dollar's exchange rate with other currencies; the value of our money should also be judged by forward-looking, inflation-sensitive market indicators, such as commodities, gold and Treasury bond spreads.

Warsh has warned that the central bank should not rely on labor-market indicators to gauge future inflation. He instead advocates a market-based price rule. This is similar to the approach used by Reagan Fed appointees Wayne Angell, Robert Heller, Manley Johnson and, for most of his term, Alan Greenspan.

And Taylor is working on a study that argues for a return to a rules-based international currency system. Several years ago, former Fed Chair Paul Volcker, who used gold and commodities as leading inflation indicators while appointed, argued for a rules-based monetary policy at home and new international currency cooperation abroad.

So if President Trump gets his tax cuts and continues his regulatory rollbacks, the economy will return to its historic norm of 3 to 4 percent growth. And faster real growth will lead to higher real interest rates and a higher real-exchange-rate value for our money.

As business anticipates much-needed tax cuts, the dollar is rising; gold is falling; and growth moves to 3 percent with minimal inflation.

This is a good thing. We're not talking about a skyrocketing currency and interest rates but important adjustments to pro-growth economic policies.

But we won't get there without a stable dollar.

If the White House, the Treasury and the Fed try to intervene for a weaker dollar, they will soon run into trouble. The tax cuts could be neutralized. Long, dormant inflation may reappear. And interest rates will wind up going much higher than otherwise would be the case.

It's a shame no one has directly asked the Fed candidates about the dollar, because more people working successfully for higher wages in a strong-growth economy do not cause inflation, as Fed models unfortunately predict. But a sinking greenback will.
