Breaking Down the Dollar's Rise

Episode Summary

Executive Summary: The episode explains why the U.S. dollar is surging as the Fed hikes aggressively while other central banks face weaker growth, different inflation dynamics, and policy constraints. Kamakshia Trivedi argues the dollar can rise further, with especially severe pressure on currencies like the pound, yen, and yuan, while selective EM currencies with early, aggressive tightening (e.g., Brazil and Mexico) have held up better.

Main Topics: Drivers of the broad dollar rally (Priority: 5/5): The dollar is strengthening because the U.S. has both resilient growth and high inflation, allowing the Fed to hike faster and more forcefully than peers. Sterling weakness and UK fiscal credibility (Priority: 5/5): The pound sold off sharply after the UK’s unfunded tax plan raised risk premia on gilts, with policymakers effectively showing a preference to support bonds even if it means a weaker currency. Why other central banks are constrained (Priority: 5/5): The ECB, Bank of Japan, and China face their own limits: fragmentation risk in Europe, yield curve control in Japan, and weak growth/easing in China. FX intervention: useful but limited (Priority: 4/5): Central banks can slow the pace of currency depreciation through intervention, but they usually cannot reverse the trend unless underlying policy and macro fundamentals change. Emerging market resilience and vulnerability (Priority: 4/5): Some EM currencies have resisted dollar strength because their central banks hiked early and aggressively, but frontier economies with dollar debt are already facing debt stress. What could end the dollar boom (Priority: 4/5): A peak in U.S. inflation, a slower Fed, and improved growth in China, Europe, and the UK would be needed for the dollar to top out.

Key Arguments: The dollar’s surge is primarily a macro story: U.S. inflation is high, growth is resilient, and the Fed is tightening aggressively in 75 bp increments. In the central scenario, Goldman expects the dollar to appreciate a few more percent in the next few months. In a hawkish scenario where U.S. inflation proves sticky, the broad dollar could rise another 5% to 7%. The pound’s weakness reflects both dollar strength and UK-specific concerns about an unfunded fiscal expansion that raised risk premia on gilts. Policy response matters more than intervention alone: if a central bank keeps rates too low relative to the Fed, its currency will likely keep weakening. FX intervention can slow depreciation but generally cannot change the direction of travel without a shift in fundamentals. The yen remains pressured because the Bank of Japan is holding yields down through yield curve control while U.S. rates rise. China’s yuan is weakening because China is easing policy to support weak growth while the U.S. is tightening. Brazil and Mexico have performed better because they began hiking early and kept pace with or outpaced the Fed. The most acute EM stress is in frontier economies with dollar-denominated debt, limited reserves, and distress/default risk. A coordinated intervention like the Plaza Accord is unlikely because the U.S. has no current incentive to weaken its currency. The dollar likely peaks only when U.S. inflation convincingly cools and growth outside the U.S.—especially in China and Europe—starts to improve.

Data Points: Expected dollar appreciation (central scenario): Another couple of percent - Goldman’s forecast for the broad dollar over the next few months Expected dollar appreciation (hawkish scenario): 5% to 7% - If U.S. inflation stays entrenched and the Fed must keep rates higher for longer Fed hike size: 75 basis points - Described as the Fed’s repeated move in its tightening cycle UK tax plan characterization: Large, unfunded, and untargeted fiscal expansion - Cited as a key reason for pound weakness and higher gilt risk premia Brazil policy rate: Close to 14% - Used to illustrate early and aggressive tightening that helped support the real Mexico policy rate: Close to 10% - Used to show the peso’s relative resilience versus the dollar China policy direction: Easing - Explains why the yuan is under pressure versus the dollar Japan policy direction: Yield curve control / capped yields - Explains yen weakness as U.S.-Japan rate differentials widen Potential timing for China policy shift: Second quarter of 2023 - Goldman economists’ expectation for a move away from zero-COVID policies Europe outlook: Recession in the euro area and the U.K. - Part of the argument for continued dollar support until growth improves abroad

Pivotal Quotes: "Under our central scenario, we think even from current strong levels, the dollar can appreciate further." — Kamakshia Trivedi: Goldman’s baseline forecast for the U.S. dollar "The Fed appears to be unconstrained. They're moving fast. That's supporting the dollar against pretty much most currencies across the world." — Kamakshia Trivedi: Explaining the main macro driver of dollar strength "Interventions can slow the pace of the depreciation of the currencies, but they're not going to change the direction of travel until the underlying fundamental macro and policy drivers change." — Kamakshia Trivedi: On the limits of FX intervention

Implications: Expect continued pressure on currencies where policy lags the Fed and growth is weak. Stronger-dollar effects should help U.S. inflation but worsen trade-offs, debt stress, and capital outflows in vulnerable markets.
