Trump’s Iran War Could Send Prices Soaring (w/ Kenneth Rogoff) | How to Fix It

The US dollar's role as the global financial lingua franca provides significant economic advantages: cheaper mortgages and car loans for Americans, lower government borrowing costs (about 1% less), and an 'incredible trove of information' from global transactions. This status also grants the US potent economic sanction power. However, this advantage is being taken for granted, and its erosion is a slow burn, not an overnight event, leading to higher interest rates and reduced power.

Rogoff explains that if the dollar's share of global transactions shrinks, interest rates will rise, costing the US money and power. He cites the UK's post-WWII experience as a former dominant currency that struggled for decades after its decline.

The escalating US national debt, combined with political attacks on the Federal Reserve's independence, directly threatens the dollar's global standing. The Fed's commitment to low inflation, replacing the gold standard, is crucial for maintaining international confidence. Both major US political parties are criticized for undermining this independence and for their reluctance to address the debt, leading to unsustainable fiscal paths.

Rogoff states that the dollar likely peaked in 2015 and that Trump's actions (exploding deficits, attacking the Fed) are 'directly out of the anti-prescription playbook.' He notes that both progressives and conservatives challenge central bank independence for different reasons.

The US conflict with Iran is not a localized event but part of a larger geopolitical struggle with unpredictable economic ramifications. While the US is an oil exporter and somewhat insulated, a significant disruption in global oil supply (20% from the region) could double or triple prices, leading to widespread inflation affecting American consumers through higher costs for goods and services.

Rogoff compares the Iran situation to the assassination of Archduke Ferdinand, an event whose full consequences were not immediately apparent. He notes that oil prices have already risen and that while the US is an exporter, higher energy prices impact 'everything' from gas to corn.

China, despite being a rising power, faces significant structural weaknesses that prevent its currency from displacing the dollar. Its economy is hampered by central planning, over-investment in infrastructure and real estate leading to 'decreasing returns,' and a lack of entrepreneurship. Conversely, Russia benefits from the current geopolitical instability, particularly from higher oil prices, which constitute half of its government revenue, and from the US diverting military resources.

Rogoff details China's 'smell of death' in areas with overbuilt infrastructure lacking businesses and ideas. He highlights Russia's benefit from increased oil prices and the US's 'openly saying we'll kind of look the other way' on Russian oil purchases by India and China.

The US is on an unsustainable fiscal trajectory, with deficits projected to reach 6-7% of GDP. Rogoff believes a debt crisis is inevitable within the next four to five years, leading to sharply raised and prolonged inflation, and further undermining the dollar. Political leaders are unwilling to implement necessary but unpopular measures like raising taxes (e.g., a value-added tax) or reforming entitlement programs, because voters are 'spoiled' and resist compromise.

Rogoff states, 'I don't see a way out of this until we have some kind of debt crisis that convinces the voter that something needs to be done.' He suggests a VAT and addressing generational wealth imbalances as potential solutions.
