Valdoria's Peg: Defend or Devalue?

The peg is under pressure for three reasons. First, inflation is 9% versus 2% in the United States, so Valdoria's real exchange rate is appreciating. Its goods are becoming less competitive, which explains the trade deficit: imports $60bn exceed exports $52bn by $8bn. Second, the central bank is losing reserves at $500m a month, or $6bn a year. With $8bn of reserves, the central bank has about 16 months of defence at the current rate, before considering any acceleration. That is a finite buffer. Third, the interest rate defence is costly: raising the policy rate from 6% to 12% may attract capital inflows, but it raises borrowing costs for domestic firms and households, worsening the credit crunch and likely raising unemployment. The peg could be sustained if the government tightens fiscal policy, slows inflation and improves competitiveness, but there is no evidence of that in the data. The reserve loss and inflation differential point to an overvalued peg. Sustainability therefore depends on how much political pain the government will accept; on current trends, the peg is not sustainable for long.

The Marshall-Lerner condition states that a devaluation improves the current account if the sum of the price elasticities of demand for exports and imports exceeds 1. Valdoria's estimated sum is 1.8 in the first year and 2.7 after two years, so the condition is satisfied in both periods. That suggests devaluation should eventually reduce the trade deficit. The J-curve describes the short-run path: immediately after devaluation, import prices rise in domestic currency and quantities adjust slowly because contracts are fixed, so the trade balance may worsen before improving. Valdoria's first-year elasticity sum of 1.8 is already above 1, but the J-curve can still occur because quantities take time to respond. A devaluation from 2.00 to 2.40 is a 20% depreciation. With pass-through of 0.4, consumer prices could rise by about 8% (0.4 × 20%), which would worsen inflation unless offset by tighter monetary or fiscal policy. The current account should improve after two years if the elasticities are accurate. However, the trade deficit is $8bn, and the improvement depends on exporters expanding capacity and on foreign demand. If Valdoria's exports are primary commodities with low supply elasticity, the improvement may be smaller than predicted.

A defensible recommendation must weigh the costs. Defending the peg with a rate rise to 12% buys time and avoids the immediate inflation shock from devaluation. It also maintains credibility and protects households and firms with dollar debts. But reserves are finite: at $500m a month, $8bn lasts about 16 months, and the credit crunch could cause a deep recession. The 9% inflation rate already erodes competitiveness, so defending may require painful fiscal tightening. Devaluing to 2.40 would improve competitiveness because the Marshall-Lerner condition holds, and the current account should improve after the J-curve. But pass-through of 0.4 implies inflation could rise by around 8 percentage points, taking inflation well into double digits. That is politically dangerous 18 months before an election. A sensible package might be a controlled devaluation combined with tight monetary policy to limit pass-through and fiscal support for low-income households. Alternatively, defend temporarily while negotiating external support and implementing supply-side reforms to raise export capacity. On the data, the peg looks overvalued and reserves are draining, so a managed devaluation is the more sustainable option, provided inflation is addressed. The worst choice is to defend with high rates, lose reserves and still devalue later.
