Managed Float
Managed Float (also known as a 'dirty float') is a type of exchange rate regime where a currency's value is primarily determined by supply and demand in the foreign exchange market, but with occasional intervention from a country's central bank. Think of it as a middle ground between a completely hands-off floating exchange rate system and a rigid fixed exchange rate system. In a pure float, the government lets the market chips fall where they may. In a fixed system, the government pegs its currency to another, like the U.S. dollar. A managed float is like a parent letting their child play freely in the park but stepping in if they run too close to the road. The central bank doesn't try to control the exact price every minute, but it will buy or sell its own currency to “manage” its value—to prevent it from getting too strong or too weak too quickly. This intervention aims to stabilize the economy, control inflation, or boost trade, creating a more predictable environment than a pure float.
How Does a Central Bank "Manage" the Float?
A central bank’s main tool is its stockpile of foreign reserves—assets held in other currencies, like U.S. dollars, euros, or yen. By trading these reserves, it can influence its own currency's price on the global stage.
Scenario 1: The Currency is Too Weak
If a country's currency is falling too fast (making imports expensive and fueling inflation), the central bank will intervene to strengthen it. It will sell its foreign reserves (e.g., sell U.S. dollars) and buy its own currency on the open market. This increased demand for its own currency helps push its value back up. It’s like a company conducting a share buyback to support its stock price.
Scenario 2: The Currency is Too Strong
If the currency becomes too strong (making the country's exports expensive and uncompetitive on the world market), the central bank will do the opposite. It will print more of its own money and use it to buy foreign currencies (e.g., U.S. dollars). This floods the market, increasing the supply of its own currency and pushing its value down. This deliberate weakening of a currency is a form of devaluation.
Why Bother with a Dirty Float?
Governments and central banks aren't just meddling for fun. They have specific economic goals in mind:
- Stability is King: Wild currency swings can create chaos for businesses and consumers. A managed float helps smooth out volatility, providing a more stable environment for planning and investment.
- Fighting Inflation: A rapidly weakening currency makes imported goods more expensive, which can lead to runaway inflation. By propping up the currency, a central bank can keep import prices in check.
- Boosting Exports: On the flip side, a country might intentionally weaken its currency to make its goods cheaper for foreign buyers. This can give a powerful boost to export-oriented industries. This is often called a “competitive devaluation” and can sometimes lead to trade wars.
- Preventing Crisis: In times of economic panic, investors might flee a country's currency en masse. A central bank can step in to prevent a complete collapse, buying time to address the underlying economic problems.
The Value Investor's Angle
As a value investor, you're focused on a company's intrinsic worth. But when you invest internationally, you simply cannot ignore the currency game. A managed float adds a layer of complexity and risk that can either supercharge or sabotage your returns.
Understanding the Impact
- Direct Hit on Returns: Imagine you buy shares in a fantastic Japanese company. The company does well, but the Bank of Japan intervenes to weaken the Yen against your home currency (e.g., the Euro or Dollar). When you convert your profits back, they'll be worth less. This is currency risk, and it's amplified by unpredictable government intervention.
- Indirect Effect on Company Fundamentals: Government intervention directly impacts the businesses you own.
- Beneficiaries: A weaker currency, managed by the central bank, is great news for a country's big exporters (think German car manufacturers or Swiss watchmakers if their currencies were managed downwards). Their products become cheaper abroad, boosting sales and profits.
- Victims: Companies that rely heavily on imported raw materials will see their costs rise if the central bank weakens the currency. Similarly, a central bank pushing the currency higher will hurt those same exporters.
What to Watch For
A managed float isn't just a technical detail; it's a reflection of a country's economic policy and health. For a value investor, it's another crucial piece of the puzzle.
- Central Bank Chatter: Pay attention to statements from central bank governors. They often signal their intentions. Are they worried about inflation (hinting they might strengthen the currency) or slow growth (hinting they might weaken it)?
- Foreign Reserve Levels: A country's ability to defend its currency depends on the size of its foreign reserves. If reserves are dwindling, the central bank may not be able to prop up its currency for much longer.
- The Big Picture: Your job is to assess not just the company's economic moat, but also the macroeconomic “weather” created by its government. A great company can still be a risky investment if it's operating in an unstable or unpredictable environment shaped by a “dirty float.”
