Federal National Mortgage Association — Fannie Mae (FNMFN)

Fannie Mae is the Federal National Mortgage Association, a government-sponsored enterprise (GSE) that buys mortgages from lenders, packages them into securities, and guarantees the principal and interest payments to investors. It is one of the two largest mortgage-market participants in America, along with its peer Freddie Mac. For decades it was a truly hybrid creature—chartered by Congress but privately held, operating with an implicit government backing that proved all too explicit when the 2008 financial crisis nearly broke the entire mortgage system. Today, despite nominally returning to profitability, Fannie Mae remains in conservatorship, meaning the federal government maintains control of the company and receives its profits.

The Depression and the creation of a national mortgage market (1938–1968)

Fannie Mae was born in 1938, near the end of the Great Depression, as a creature of necessity. Before Fannie Mae, buying a home in America was fundamentally local. A person would save a large down payment—often 30 or 40 percent—then borrow the remainder from a local bank or savings and loan. That bank held the mortgage until it was paid off, sometimes decades later. The system worked reasonably well in normal times but was brittle: local banks could fail, taking mortgages and deposits with them; local credit cycles could tighten, starving the housing market of capital; and the illiquidity of mortgages meant that capital sat tied up in individual loans instead of flowing freely to wherever it was needed most.

When the Depression hit and millions lost their homes to foreclosure, Congress recognized that a national mortgage market—one in which mortgages could be bought and sold like securities—would make the housing market more resilient. Fannie Mae was chartered as a quasi-public corporation to buy mortgages from local lenders, freeing up capital so those lenders could make new loans. The company would hold or sell the mortgages to investors. By converting illiquid local mortgages into tradeable securities, Fannie Mae would create a national market and stabilize housing finance.

For its first several decades, Fannie Mae grew modestly and stayed close to its mandate. It bought mortgages insured by the Federal Housing Administration and Veterans Administration—government-backed loans that were relatively safe. The company issued bonds to raise capital, then used the proceeds to purchase mortgages. The structure created a crucial advantage: because Fannie Mae was chartered by Congress and backed by the government’s credit, investors trusted it. They would buy Fannie Mae bonds and mortgage-backed securities at yields only slightly higher than Treasury bonds, giving Fannie Mae cheap funding relative to purely private lenders.

Expansion and the secondary market (1968–2007)

In 1968, amid the Great Society and the Vietnam War, President Lyndon Johnson spun Fannie Mae off from the federal government and made it a private corporation, while keeping the implicit government guarantee. The motivation was partly political—getting a large liability off the federal balance sheet—but it unleashed Fannie Mae’s growth. As a private company, Fannie Mae could raise capital more easily, pay market salaries, and expand without navigating the federal procurement and governance processes.

Over the following four decades, Fannie Mae and Freddie Mac (chartered in 1970) came to dominate American mortgage finance. By the early 2000s, they purchased or guaranteed roughly half of all mortgages issued. The mortgage-backed securities they issued became the foundation of the mortgage market: banks that originated loans sold them to Fannie Mae, got cash back, and made new loans. Investors bought Fannie Mae securities and received cash flows from the underlying mortgages. The process was efficient and created liquidity—lenders were no longer stuck holding mortgages for decades, and capital flowed readily into housing.

The business model was simple: Fannie Mae earned money primarily on the spread—it bought mortgages at one rate and sold securities at a lower rate, pocketing the difference, while also collecting guarantee fees from investors who wanted Fannie Mae to promise to cover losses if borrowers defaulted. Because the implicit government guarantee was so powerful, Fannie Mae could borrow very cheaply, which made the business profitable. Shareholders benefited from the spread, and the company returned capital in dividends. The government, for its part, had created a national housing market and implicitly promised to bail out Fannie Mae if anything went seriously wrong.

The crisis and conservatorship (2008–present)

In 2007 and 2008, the mortgage market collapsed. The wave of subprime mortgages—loans to borrowers with poor credit or minimal down payments, originated in a frenzy of bad lending—suddenly started defaulting as housing prices fell and adjustable rates spiked. Fannie Mae and Freddie Mac, which had expanded aggressively into these riskier mortgages during the boom, faced mounting losses. By September 2008, both companies were near insolvency.

The federal government stepped in and placed both Fannie Mae and Freddie Mac into conservatorship—a regime in which the government (via the Federal Housing Finance Agency) took control of the company to stabilize it and prevent complete failure. Under conservatorship, the government injected tens of billions of dollars of capital into Fannie Mae to cover losses. The company continued to operate and purchase mortgages—indeed, in the aftermath of the crisis, government-backed lending became the main way Americans could get mortgages, because private lending had nearly stopped. Fannie Mae became even more central to the mortgage market.

Over the years, Fannie Mae’s credit quality improved. The mortgages it held and guaranteed began performing better as the housing market recovered. By the mid-2010s, the company was posting profits and returning capital to the Treasury to repay the emergency injection. But it remained in conservatorship. The government, through Congress and the FHFA, maintained operational control and captured all profits.

This created a peculiar situation: common shareholders—anyone holding FNMFN or other Fannie Mae equity—owned a company that was technically solvent and profitable but that was generating no value for them. All profits went to the government. Preferred shareholders faced a similar bind: they received their dividends only if the conservator allowed it, and the government determined whether the company would stay in conservatorship indefinitely or eventually be returned to private hands.

The mortgage guarantee business in conservatorship

Today, Fannie Mae’s role in the mortgage market is essentially structural. The company purchases mortgages that conform to its underwriting standards (conventional mortgages, not subprime, with borrowers meeting minimum credit and income tests). It bundles them and issues mortgage-backed securities, guaranteeing investors that they will receive principal and interest even if borrowers default. In exchange, Fannie Mae collects a guarantee fee—typically a fraction of a percent of the mortgage balance annually.

This is not a particularly profitable business in normal times; the guarantee fee is competitive, and the cost of funding is driven by government-bond yields plus Fannie Mae’s credit spread. The profit comes primarily from the volume: Fannie Mae now effectively guarantees roughly half of all mortgages in America, and the scale of that business generates reasonable profits. But those profits are now captured entirely by the federal government, not by shareholders.

The company’s risk profile remains significant. If housing prices fell sharply, mortgage defaults would spike, and Fannie Mae would face large losses. The government has effectively promised to absorb those losses (through capital injections), but that promise was forged in a crisis and could be tested again. Additionally, the structure of conservatorship—with the government as the beneficiary—creates uncertainty about whether shareholders will ever receive returns. The market’s low prices for Fannie Mae equity reflect that uncertainty.

Policy debates and long-term uncertainty

For more than a decade, there has been debate in Congress and the housing-finance industry about the proper future of Fannie Mae and Freddie Mac. Some proposals would wind down the GSEs and shift mortgage risk entirely to the private market. Others would keep them in place but reform their governance or capital structure. So far, no comprehensive reform has passed, and Fannie Mae remains in conservatorship—neither fully private nor fully public.

For equity holders, this limbo is the central risk. A shareholder holding FNMFN is betting either that Congress will eventually restore Fannie Mae to private status and allow it to pay dividends again, or that the conservator will begin return cash to equity holders while still in conservatorship. There are no guarantees, and political will to move on the question has proven weak.

How a Fannie Mae shareholder would research the company

Anyone holding or considering Fannie Mae equity should monitor the Federal Housing Finance Agency’s filings and congressional testimony. The FHFA oversees the conservatorship and sets policy for Fannie Mae. Additionally, track the company’s 10-K and quarterly earnings, though remember that all profits flow to the Treasury, not to equity holders. Watch for any legislative initiatives related to GSE reform, as changes to Fannie Mae’s charter or status could materially affect shareholders.

The mortgage market’s performance also matters: if housing enters a prolonged decline, Fannie Mae’s losses and capital needs would spike, deepening the government’s financial commitment and making an exit from conservatorship even more distant. Conversely, a strong housing market and stable mortgage performance improve the likelihood that the government might eventually consider returning the company to private ownership.
