This section explores how election cycles and political factors influence fiscal and monetary policy, shaping economic outcomes and investor decision-making. We also examine the role of central bank independence, political gridlock, and policy reversals that affect global markets.
So, has it ever crossed your mind that politicians might, well, tweak policy just before an election to make things look rosier? Trust me, you’re not the only one. Many economists have formalized this observation within the concept of political business cycles. In short, during an election year (or any critical transition in leadership), governments sometimes ramp up spending, cut taxes, or push other measures that stimulate the economy—at least in the short run. Meanwhile, monetary authorities might feel overt or subtle pressure to keep interest rates low so that people see a surge in growth, ultimately giving some extra sparkle to the incumbent administration’s popularity.
That said, there is a big risk: what looks like a nice boost during campaign season might come back to bite the economy later. Debt levels can shoot up, inflation might edge higher, and the long-term structural integrity of the economy may suffer. And guess what? That is precisely where the study of political cycles and election effects gets so fascinating—and, of course, relevant to your CFA program.
Below, we explore key theories and practical realities of how political motivations can decisively shape macroeconomic policies, yield curves, currency exchange rates, and investor sentiment. Uncertainty about policy direction—and whether it’s driven by genuine market considerations or short-term political posturing—can introduce serious volatility into financial markets. Let’s dig in.
A political business cycle occurs when those in power manipulate fiscal and/or monetary policy levers to produce favorable short-term economic outcomes that coincide with election timelines. For example, politicians might push for:
All of these can translate to quick votes if timed right, but the catch is that once the election passes, the economy often faces a “hangover.” Debt might be higher, inflation could accelerate, or structural reforms that are badly needed get postponed to avoid hurting election prospects.
You know how you might delay a big project at work—or put it aside—until after the weekend, so you don’t spoil your fun plans? Politicians sometimes do the same. One memorable (though somewhat dramatized) example many textbooks highlight is from the 1970s in various industrial democracies, where expansions in government spending often suspiciously lined up with election timetables. Whether or not it was intentional, many economists saw a pattern. With advanced econometric methods, these phenomena were codified into the notion of the “political business cycle.”
Public choice theory posits that policymakers are not solely altruistic guardians of the public interest. Rather, they are individuals driven by self-interest—just like the rest of us. Lobbyists seek policy favors, bureaucrats might want larger budgets for their departments, and politicians want reelection. This could lead to:
Imagine a scenario where a government invests a hefty sum in a stadium project in a key voter district right before the election. The net economic benefits might be modest or even negative in the long run, but it helps incumbents garner local support. These short-term political moves frequently distort capital allocation, hamper fair competition, and can inflate government debt without delivering meaningful productivity gains.
Conservative or progressive, populist or liberal—each ideology frames a distinct policy agenda. Some parties emphasize cutting taxes and reducing government deficits. Others prioritize welfare programs, healthcare, and social insurance, leading to higher public spending. So, if you see a shift from a conservative to a progressive regime, expect:
Political leanings can also shape the environment for monetary policy. While many modern central banks strive for independence, a populist regime might push for looser monetary policy to spur short-run growth, or a more conservative regime might deem it crucial to contain inflation through tighter controls.
Sometimes governments defer tough reforms—like pension restructuring or subsidy cuts—because they don’t want to upset voters. Picture an administration that knows they need to overhaul the tax code or streamline entitlements but postpones it until after the election, hoping to preserve their popularity in the near term. This procrastination can create cyclical waves of policy uncertainty.
Policy reversals can also happen if the incoming administration takes a radically different view or has different allies in the legislature. From an investor standpoint, such abrupt changes can bring about:
A central bank that operates free from direct political influence can moderate election-driven impulses. The typical design includes:
An independent central bank often resists excessive monetary expansion pre-election, thereby damping the amplitude of political business cycles. Markets typically prize such independence, rewarding economies with lower risk premiums. However, in some countries, central bank autonomy is limited or under constant pressure, making it easier for politicians to press for loose monetary policy that might buoy pre-election growth.
If no single party has a majority, forming a coalition or dealing with an opposing legislature can slow policy approval. Gridlock can be, well, frustrating but also ironically beneficial at times. It may prevent detrimental or extreme policies from quickly materializing, offering a form of checks and balances.
Unfortunately, gridlock can also stall crucial measures—think deficit control, infrastructure spending, or regulation for critical sectors. Prolonged uncertainty can strain investor sentiment, spike borrowing costs if credit rating agencies factor in legislative inertia, and hamper the administration’s ability to respond swiftly to economic shocks.
Investors keep a keen eye on sovereign bond yields heading into election season. If they suspect the government will engage in election-season largesse or adopt populist measures, yields may rise to factor in inflation, default risk, or both.
Uncertain election outcomes can rock the currency markets. If the incumbent’s reelection is uncertain, or if a populist candidate with expansionary (and possibly inflationary) policies is gaining momentum, currency depreciation can ensue beforehand. Conversely, a victory by a market-friendly candidate might lead to currency appreciation.

When markets anticipate an election surprise, forward currency contracts adjust rapidly to reflect the perceived risk of a drastic policy shift. If you want to estimate how an unexpected election result might change currency rates, you can:
A simple formula for forward exchange rates can appear as:
But in reality, you might add risk premium terms to capture the election-induced volatility:
To gauge the immediate cost to government financing if an “election surprise” occurs, you can compare the country’s bond yield to a risk-free benchmark (often US Treasuries). Suppose the spread widens after an unexpected result—this indicates more perceived risk or potential default concerns.
It’s tempting to see elections as purely political events, but for global investors, they often mark periods of sharp policy shifts, volatility in money markets, or sudden changes in interest rates and yields. Understanding political cycles and election effects on policy is crucial for anticipating macroeconomic outcomes and hedging portfolio risk—especially at the CFA Level II exam, where item-set vignettes often blend politics, economics, and market data into a single scenario.
Analyzing how politicians’ self-interest interacts with central bank policy, public finance constraints, and the broader global economy is an essential skill. You may find yourself reading a vignette about “unexpected spending packages” or “surprise election outcomes” and be asked to gauge the impact on sovereign yields or currency forward rates. Be aware of the short-term boosts, the long-term consequences, and the market’s probable reaction.
• When reading the vignette, quickly identify any reference to elections, newly passed spending measures, or external commentaries about the central bank’s alignment with government.
• Recognize that short-term boosts to employment or GDP might not be sustainable. Try to see how this affects indicators like inflation, debt sustainability, or bond market sentiment.
• If central bank independence is highlighted (or threatened), consider how that changes your expectation for monetary policy.
• Evaluate risk premiums in both currency and bond markets when faced with surprising election results or policy reversals.
• Time management: these vignettes can have a lot of contextual “fluff.” Highlight the numbers that matter—e.g., new spending levels, changes to the policy rate, or inflation data—and separate them from background political commentary.
